T-Daq Miniature Thermocouple Scanner
• Acquires K and E type thermocouples
• Accurate to +/- 0.5 DegC
• Compatible with any intelligent pressure scanner acquisition system.*
• On board EPROM contains calibration coefficients.
• Can be in-field reconfigured for different thermocouple types.
• Up to 1250Hz per channel acquisition speed.
• Can be used with other Chell products as part of a miniature acquisition system.
The Chell T-Daq is an intelligent, compact and high accuracy temperature scanner that multiplexes 8 thermocouple inputs into a single output. The electrical interface is exactly the same as the Pressure Systems (TE) DTC pressure scanners. The I-Daq can therefore be substituted for a pressure scanner in an existing DTC system to provide additional temperature measurements.
The T-Daq features an internal EEPROM that contains the configuration of the T-Daq and its calibration coefficients. When connected to the acquisition system, the T-Daq’s coefficients will be uploaded so that an engineering unit temperature output can be generated. Re-calibration is a simple matter of reprogramming the EPROM and can be done off-line. The T-Daq can be calibrated for a number of different thermocouple types. The type used can then be selected with links in the mating Omega connector.
