CANdaq and QUADdaq Acquisition Systems

T-Daq

The Chell T-daq is an intelligent thermocouple temperature scanner capable of acquiring the outputs of K and E type thermocouples. It can be used in place of a PSI pressure scanner or in conjunction with the Chell CANdaq or QUADdaq products to provide a complete data acquisition system.

• 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 DTC pressure scanners. The I-Daq can therefore be purchased with the Chell CANdaq or QUADdaq to provide a complete acquisition system. Alternatively, the I-Daq can be substituted for a pressure scanner in an existing DTC system to provide additional temperature measurements. When used with the QUADdaq, the T-Daq can be used in conjunction with the pressure scanners and the Chell I-Daq to provide a multi-input acquisition system.	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.
