Intrinsically Safe 32 channel Temperature Multiplexer

In refineries, the temperature is one of the highest volume measurements that exists.  Reducing the cost of these measurements, which are often in hazardous areas, is always a top priority.

When you have several temperature points that are located in hazardous areas, look to the TCS Temperature Concentrator System. The TCS consists of one or two TCMs and an HMC. The TCM is a 16 channel universal temperature multiplexer that communicates to the HMC via HART.  The HMC in turn converts the HART temperature data into MODBUS RTU protocol for the DCS to read. The TCM can be installed in Class I Div 1/Zone 0 areas and can multiplex up to 32 channels of temperature per HMC. This drastically reduces the temperature cost per point as opposed to running sensor extension wire all the way back to the DCS or control room.

Key attributes:

  • 32 channels of multiplexed temperature reduces the cost per point
  • PC programmable TCM and HMC with free programming software
  • Worldwide hazardous area approvals
