Body Temperature Monitoring System
Our MetaMeter
telemetry-based body
temperature measurement systems are designed
with Sable Systems' famous attention to accuracy
and high resolution. Consider this graph,
created with the aid of Hershey, our in-house
rodent-American telemetry tester:
You will notice a few
things, relative to what you may be used
to with legacy body temperature monitoring
systems. The most important are high resolution,
and excellent data integrity. You might
be wondering what secrets the fine structure of
this graph might contain, now that you can see
body temperature fluctuations so clearly.
Our customers have been
asking us to make accurate, high resolution body temperature monitoring
systems for many years. For a variety of reasons
we didn't want to enter the field. Finally, we
relented.
Here are the features of our new MetaMeter
system:
Use your legacy telemeters with our intelligent,
networking bases that store calibration data
Resolution: 0.01 °C, accuracy: 0.1 °C, range as
calibrated, up to 0 - 50 °C
Bases display actual telemeter temperature to
0.01 °C via LED display every 2 seconds
Only one master station
is required for up to 250 bases
Each base can also
measure activity and ambient temperature plus 2
counters & 2 analog inputs
Network and power
connection are made via simple daisy-chained
telephone quad cable
Interference-proof, fully
digital interconnections (length up to 1 km!)
Zero programming
interface with graphic data analysis & text
export
Scientists who have
required body temperature monitoring over a wide
range of temperatures, such as those encountered
in hibernation or torpor studies, have long been
frustrated by the fact that existing
manufacturers of telemetry systems have not (in
their opinion) been particularly sensitive to their concerns. For example, expensively
re-calibrated telemeters are tested at just two
frequencies, and a linear line drawn between
them - even though the relationship between
telemeter temperature and output frequency is
anything but linear!
We have researched this
problem, and for users of wide-range systems, we
have developed proprietary non-linear
mathematical functions that allow extremely
accurate calibrations to be made. Here is an
actual example of raw frequency-temperature
data, and you can judge by yourself how adequate
a two-point linear calibration between, say, 15
and 40 °C would be. Especially at intermediate
temperatures.
This calibration curve,
incidentally, was generated by one of our
MetaMeter prototypes in conjunction with the
built-in ramping and stepping functions of our new
PeltPlate
intelligent heat/chill plate. We can
supply a complete non-linear telemeter
calibration system on request. We can also
supply base units that are stand-alone, for
integration of telemetered body temperature into
other experimental setups without the
requirement for tedious importation,
after-the-fact synchronization, and de-glitching.
We are willing to
customize our systems for customers with unusual
requirements. We believe you won't find a
more flexible supplier of telemetry-based body
temperature monitors, nor one as convinced of
the importance of uncompromising accuracy and
high resolution. We know and respect the
requirements and motivations of research
scientists. We're not imitators. We're
innovators.
The MetaMeter is now in
production. We have already delivered complete
systems,
and we invite you to contact us with any questions you may have
about the MetaMeter system or any of our other
products .
Imitators please note: The
MetaMeter is protected by a pending patent.
Sable Systems is a company founded by scientists for scientists.
We are certain that you will enjoy doing business with us.
