The DTS3250 Digital Thermocouple Scanner is ideal for use in
turbine engine, diesel engine, and compressor test cells, as well
as other industrial environments such as boiler and oven
temperature monitoring. The module has a stainless steel enclosure
with a lid for input terminal access. The standard DTS is
insulated, rugged, and splash resistant. The DTS3250's electronics
were specifically designed to endure punishing high EMI noise
environments while still being able to provide accurate engineering
data. This allows the DTS3250 Intelligent Scanner is
typically mounted in close proximity to the test article, thus
minimizing thermocouple wire lengths. Shorter thermocouple wires
not only reduce errors, but also lower costs due to the elimination
of extension cables. Field calibrations can be used to modify
coefficients which can also improve end to end accuracy. The
standard DTS3250 module accepts two wire or three wire shielded
thermocouples.Also included as standard are environmental shock
mounts. The 64 channel DTS3250 modules are optionally available
with a 19 inch rack mount kit.
Model DTS3250, Digital Temperature Scanner, accepts 64
thermocouple inputs. It incorporates RAM, Integral Low Pass
Filters, 22 bit A/D converters and a microprocessor in a rugged
stand alone module. An isothermal block is incorporated for the
Uniform Temperature Reference (UTR) for each 16 channel input. NIST
thermocouple tables for standard thermocouple types are stored in
flash memory. The microprocessor uses these look-up tables to
convert mV inputs to Engineering Units. Temperature data are output
in °C, °F, °R, K, millivolts and counts.
The DTS3250 accuracy for types E, J, K, N, and T is ± .25°C to
±2.0°C depending on the thermocouple type and the useful
temperature range. Multiple standard thermocouple types may
be used with one intelligent thermocouple scanner, model
DTS3250.
