TEMPERATURE TRANSMITTER

We want to have a single  temperature sensor with two transmitters or two temperature sensors within same thermowell which can be configured for two transmitters independently... is it possible to have?

  1. if so suggest me the model number and details...

  • Rosemount 0078 dual sensor RTD with a 3144P or 644 transmitter. Both xmtrs can take in 2 independent sensors.

    do both sensors can be configured in 4-wire RTD mode ???

  • In reply to chandu:

    The dual element RTD sensors only have room in the sheath for six wires so it is two 3-wire RTD's.  Both the 644 and 3144 can take both sensors as inputs and provide a single analog output. However the two sensors can also be wired to two independent transmitters if they are being connected to different systems which is quite common.
