How Important is Your Temperature & Humidity Data?
As important as your critical product and processes.
Veriteq's fail-safe and easy-to-install data loggers for temperature
monitoring and humidity monitoring and validation never lose data and never let
you down. Why? Because each data logger is powered by a 10-year battery
and has on-board memory that records independantly of your network or power.
In Life Science facilities, Metrology/Calibration labs and Electronics
manufacturing environments, temperature and humidity data loggers are often used for monitoring and alarming to safeguard products
and processes. Additionally, reliable documentation is required for quality reviews and audits, as well as meeting
regulatory and accreditation requirements.
Although most buildings are equipped with centralized systems for
heating and air conditioning, most of these systems can't fulfill
accurate, industry-specific monitoring, recording, and reporting requirements.
Depending on the needs of the facility, the choices typically then
come down to one or more of three basic methods: Manual "pen
and paper" systems, Chart Recorders, or a secondary centralized
hard-wired system.
Each of these methods offers various advantages and disadvantages
particular to each industry. Consequently, facility managers often
have to make difficult compromises to get the temperature monitoring
system that fits both their needs and their budget.
However, systems that are based on a network or mechanical devices
like chart recorders come with the inherent risks of lost and inaccurate
data. Veriteq's monitoring system combines all the advantages of other
methods with none of the downsides.
Traditional Monitoring & Recording V. Networked Data Loggers
Manual Data Collection: More common than you'd think
Surprisingly, manual humidity / temperature monitoring and data collection
methods are still in wide use today. Such methods typically involve
one or more operators recording initialed readings on a regular basis
from a fixed read-out device (such as a digital thermometer or hygrometer).
These readings are usually entered on a prominently displayed chart
next to the area of interest, such as a refrigerator, freezer, or
chamber.
Recording temperature and humidity readings in this manner has some
obvious advantages: there is minimal equipment to purchase, there
is next to nothing to maintain.
However, manual systems can be very expensive to operate and are
often unreliable. Most problematic however, is the time lost to manually
gathering temperature and RH data.
One hospital estimated labor costs
of 3,000 hours per year of valuable nursing time was taken up performing
routine checks on monitored environments. The same hospital frequently
had to deal with missing data that impacted their need to meet regulatory
requirments. Critical products were at risk by this unreliable, error
prone system of monitoring temperature and humidity.
In this instance, the risk to product increased during off-hours,
when limited resources resulted in missed temperature checks. In such
cases, problems can undetected for days, resulting in serious damage.
For the above reasons, many Life Science facility managers can easily
justify the costs of a move from manual methods to an automated system.
Chart Recorders: Old technology at New Market prices
Chart recorders are one of the most popular ways to automatically
collect and locally display data. They record and display operating
data on paper charts which are then changed regularly and archived,
usually on a weekly basis.
Chart recorders are relatively easy to deploy, power wiring is
usually all that's required, and they have often been included
as a built-in feature of various equipment. Although expensive,
chart recorders are relatively simple to operate and provide local
display of real-time and short-term historical data.
But for all their advantages, chart recorders are still dependent
on manual processes to function properly. Charts and pens must
be changed regularly or else valuable information is lost. Being
mechanical devices, they cannot provide the kind of measurement
accuracy that critical monitored environments require. Chart recorders
are prone to periodic mechanical failures and require frequent
re-calibration.
In addition, in today's increasingly "connected" world,
chart recorders are now recognized as isolated devices that cannot
be monitored, alarmed, or otherwise accessed remotely. This serves
to make data retrieval, required when the auditors arrive, a time-consuming
and tedious process.
Centralized Monitoring Systems:
Cheaper, Better & Nework Ready
Centralized monitoring (CM) systems consist of a network of remote
sensors that are literally wired back to distributed or centralized
input panels. Not to be confused with Building Automation Systems,
a CM system is an auxiliary system tailored to the specific monitoring
and reporting requirements of a particular industry.
CM systems offer many advantages including remote temperature
monitoring, alarming, and reporting. By avoiding the need for
manual data collection and chart replacement, such systems are
a significant time-saving alternative to chart recorders and manual
methods.
The main drawback to CM systems is that they are costly, prone
to system-wide failures, and are limited in their ability to display
localized information. A typical CM system requires expensive
data acquisition equipment as well as a proprietary hard-wired
network. Installation and wiring costs can often be prohibitive,
particularly in older buildings. The large capital expense of
such systems can also lead to a protracted budget approval process.
Centralized systems are also prone to global failures that can
result in missed records and unreliable reporting. For example,
system viruses, computer crashes, network failures, power outages,
or operator errors can interrupt the data collection process throughout
the whole system.
An often overlooked issue with CM systems is their inability
to display data on a localized basis, a key requirement in many
industries. Instead, data can only be viewed or retrieved at a
central location.
A Fail-safe Solution: viewLinc + Networked Data Loggers
viewLinc is Veriteq's networked data logging (Net/DL) system. The
viewLinc software connects to Veriteq data loggers that record autonomously
and can be connected to an existing computer network for display and
alarm.
Each data logger is a completely independent data collection device
with integrated temperature or temperature and humidity sensors, memory,
clock, and 10-year battery. The loggers interface to an existing network
either through a computer on the network or through a device server.

Networked data logging systems like Veriteq's differ from conventional centralized monitoring systems
in that they employ a highly distributed architecture. While each
module is independent and capable of collecting data on its own -
without reliance on a network or power connection - it's data is also
highly accessible - on a historical and real-time basis - to permit
central monitoring and alarming. This architecture makes data logger based monitoring systems
exceptionally easy to install, scalable, accessible, reliable, and
cost-effective. The following summary discusses these points further:
Networked, Battery Powered Data Loggers: Easy, Scalable, Smart
A key advantage of Veriteq's viewLinc system is how easily, quickly,
and inexpensively the data loggers can be deployed and later expanded
as required by the needs of your monitored environment. Users can start small
and grow a system gradually, avoiding the delay of approving large
capital expenditures. And with Veriteq's OPC
servers, our data loggers can even connect to other Windows-based
monitoring systems.
Veriteq's data logger based system is easily scalable according to user requirements, from
a single data logger and workstation location to a system of an unlimited
number of data loggers and multiple monitoring stations. In addition,
Net/DL systems are flexible: modules can be easily relocated without
difficulty, allowing measurements to be taken precisely at the area
of interest, rather than on a distant lab wall.
Centralized vs. Distributed Monitoring & Alarming
Centralized monitoring saves operational costs and guarantees better
system operation, as monitoring can be more easily carried out by
a smaller number of dedicated personnel. Net/DL systems have the same
advantages as hard-wired centralized monitoring systems: remote monitoring,
alarm notification, automatic data collection and archiving.
However, because our system uses your existing LAN, information can
be easily disseminated at each workstation rather than only at a central
location. In addition, viewLinc can be easily interfaced with the
network's e-mail system to deliver alarm messages and status information
remotely.
Redundant Data Storage: Never lose data again
Each Veriteq data logger records redundantly, collecting and storing
data in the on-board memory. This is crucial in applications where
missing data can have expensive consequences. With viewLinc, not only
is data collected locally and independently within each data logger,
the data is regularly backed up across the network to one or more
remote locations. Even if your whole network is down or if there is
a power outage, you'll never lose data.
Efficient Data Retrieval:On-demand Reporting
With the viewLinc Net/DL system you can set up automatic regular
downloads of data logger information to one or more central locations.
This data then is safely archived and accessible and can be used to
create detailed reports on demand.
Cost-Effectiveness: Scale the system to match your needs
Throughout the system, user-friendliness, reliability, scalability,
and network accessibility are the key factors that reduce the running
costs and give a higher return of investment for Net/DL systems. In
addition, most users also have discovered that Net/DL systems are
very affordable, since companies already have many components of the
system in place (such as a Local Area Network and existing PC's).
The No-compromise Data Logging Solution
When it comes to deciding on the monitoring and data collection needs
of your facility, choosing an appropriate type of monitoring system
involves a number of factors and compromises. Such compromises include
initial cost, operating costs, implementation schedule, and functionality.
However, with the improvement of networking technologies, many of these compromises
need never be made. viewLinc effectively leverages your existing network to provide flexibility, fast installation, suberb
accuracy and total reliability.
