The DTS3250 series temperature acquisition system represents the next generation of intelligent thermocouple scanning. Model DTS3250, Digital Temperature Scanner, accepts 16, 32, or 64 pairs of 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 ±0.25°C to ±0.5°C depending on the thermocouple type and the useful temperature range. (Refer to accuracy table.)
Multiple standard thermocouple types may be used with one intelligent thermocouple scanner, Model DTS3250.
Applications
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 locking lid for input terminal access. The standard DTS is insulated, rugged, and splash resistant. Also included as standard are environmental shock mounts.
The 64 channel DTS3250 modules are optionally available with a 19 inch rack mount kit. 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.
