TCS Miniature RTD Transmitter  

   

RTD-TC-Cal Computer Interface Module / RTD-TC, RTD Transmitter Coupling (BACK) / RTD-TC, RTD Transmitter Coupling (FRONT)

Application:

RTD-TC, RTD-Transmitter Connector for direct connection to OEM PRTD probes. The transmitter connector is a stainless steel housed, miniature, isolated, software programmable,  4-20 mA transmitter designed to be coupled to a 100 ohm, 3 wire, 385 single RTD probe fitted with three pin standard connector. Generally used in high accuracy applications. The PRTD assembly can be recalibrated at any time, to check sensor stability and or extend the useful life of the RTD probe.


 Construction:

  • Glass filled thermoplastic connectors.

  • Stainless steel hermetically-sealed transmitter housing.

  • Teflon insulated lead wire.

Termination:

  • Probe termination, is standard three pin plug or jack.

  • Instrument termination is 10 feet of Teflon insulated wire.  

  • Custom probe terminations are available for round military type multi-pin connector or similar water proof connectors. Please consult the factory.

Temperature rating:

  • Transmitter is rated for -80 to 100 oC
