Resumen

The Granite™ Temp 120 is a purpose-built thermocouple measurement module. It has 20 thermocouple inputs using universal-alloy miniature thermocouple jacks. The Temp 120 is made to handle extreme temperature environments and rapid thermal gradients applied to the measurement module. It has a dedicated temperature reference for every input terminal and is carefully designed to reduce temperature errors in the presence of external temperature gradients.

Descripción detallada

The inputs of the Temp 120 are a universal copper-copper junction and can accept any standard thermocouple alloy type. The Temp 120 is part of a data-acquisition system that includes a DAQ such as a Granite 6, 9, or 10, or the CR6 or CR1000X Dataloggers. The clock timing synchronization across modules is managed by the DAQ or data logger via the CPI communication port. The time base can be referenced either to GPS or a temperature-compensated real-time clock. Applications requiring hundreds of terminals of thermocouples can be easily assembled as a single data-acquisition system. Measurement modules can be collocated or spread out via a networking cable to be closer to the point of measurement.

  1. How can CANOut be enabled on the Volt 108/116 or Temp 120 modules?

    Only the XD versions (not the SD) support CANOut 2.0b. To enable this function, use our SURVEYOR software. When SURVEYOR recognizes an XD module, a CAN Enable menu appears with a “CAN Enabled” slider switch.

  2. Can the CAN Message ID be selected for the Volt 108/116 or Temp 120 modules?

    Yes, a specific CAN ID can be selected for each module.

  3. Do the Volt 108/116 XD and Temp 120 XD versions support Big Endian or Little Endian byte format?

    The Volt 108/116 XD and Temp 120 XD output CAN2.0b data frames in Big Endian byte format.

  4. Are all measurement types that are available to the Volt 108/116 XD and Temp 120 XD supported in CANOut?

    All outputs except strain gauge calculated microstrain are supported in CANOut:

    • Volt SE/Diff output in mV
    • BridgeFull in mv/V
    • BrHalf3W and BrHalf4W in Rs/Rf
    • Temp 120 output in desired temperature units

    Note: Strain values are in mV/V and either need a data logger or post processing to calculate microstrain.

  5. Are both 11-bit and 29-bit CAN message identifiers supported for the Volt 108/116 and Temp 120 modules?

    Yes, both 11-bit and the 29-bit (extended) message identifiers are supported.
