Isolated | Non-isolated

The Richards TS and TSI series transmitters are available for both thermocouples and RTD inputs.

The thermocouple inputs cover all standard calibrations. RTD inputs cover three and four wire, Pt100, alpha 0.00385 (European or DIN Standard) and three and four wire alpha 0.003916 (American Standard) sensors. The output is temperature linearized 4-20 mA VDC. All of our transmitters are 2 wire looped powered. TS and TSI series transmitters can be mounted in the following DIN-B compatible connection Heads:   ASLH, SH, AFTH, WH, CIH, EXSHT, NH, and PPSH.

Part Number Construction:

 √  1) Select the series TS (Non-isolated) or TSI (Isolated).

√  2) Select your thermocouple Type: B, C (AE), E, J, K, N, R, S, T

or select your RTD Type: PTE (European Curve), or PTA (American Curve)

√  3) Select your temperature span.

√  4) Select your degrees Celsius or Fahrenheit.

Example (Thermocouple): TSK500-1000F (Non-Isolated, Type K thermocouple, Span 500-1000°F)

Example (RTD): TSIPTE0-500C (Isolated, Pt100, European Curve, RTD, Span 0-500°C)

  !   Note: When using thermocouples with grounded junctions, be sure to use our TSI series transmitters.
