Measurement Computing CIO-DAS-TEMP - Manual (Page 8)

Semiconductor temperature sensors may be purchased from some electronics distributors or directly from
Measurement Computing Corp. An AD592 potted into a stainless steel probe may be purchased from
Measurement Computing Corp. or from other vendors of temperature sensors.
The AD592CN has excellent specifications for ambient temperature measurement (see chapter on
specifications).
In addition, because it is a current-output device, the AD592CN is relatively immune to noise pickup and
IR drops in the signal leads w hen used remotely. I t is reasonably rugged and will withstand supply
irregularities and v ariations or rev ersals up to 20V. Since the A D592s are laser- trimmed, they are
interchangeable and have a high initial accuracy that does not degrade over time

(six inch, CN
specifications). T he SNSR-AD592-PRB6CN is
composed of an AD592 connected to two lead
wires, inserted into a stainless steel probe and
potted in place.
The unit is waterproof.
There are two wires protruding from the probe.

4 PROGRAMMING AND APPLICATIONS
Although the CI O-DAS-TEMP is part of the larg er DAS fam ily, there is no correspondence between
registers. S oftware written at the reg ister level for the other D AS's will not w ork with the
CIO-DAS-TEMP.
PROGRAMMING LANGUAGES
The UniversalLibrary program provides complete access to the CIO-DAS-TEMP functions from a range
of programming languages; both DOS and Windows. I f you are planning to write programs, or would
like to run the example programs for V isual Basic or any other language, please refer to the
UniversalLibrary manual.
PACKAGED APPLICATION PROGRAMS
Many packaged application programs now have drivers for the CIO-DAS-TEMP. I f the package you own
does not appear to hav e drivers for the CI O-DAS-TEMP please fax the package name and the rev ision
number from the install disk s. We will research the package for you and advise by return fax how to
obtain CIO-DAS-TEMP drivers.
