YOKOGAWA K9142TH Temperature Sensor | Thermowell Assembly, High Temperature, 1/2" NPT, RTD

YOKOGAWA K9142TH temperature sensor specifications. High-temperature RTD sensor assembly with thermowell, 1/2" NPT thread, up to 600°C.

Product Overview

The YOKOGAWA K9142TH is a high-temperature temperature sensor assembly from the K Series. It consists of an RTD (Pt100) sensor element housed within a heavy-duty threaded thermowell, specifically designed for elevated temperature industrial processes. The assembly enables accurate and reliable temperature measurement in demanding thermal environments while allowing sensor removal without process shutdown.

Important Notes

1. The exact insertion length, thermowell material, and connection type are defined by the full model suffix.

2. For service above 400°C, specialized thermowell materials (e.g., Inconel) and sensor construction are required.

3. The assembly includes the thermowell and Pt100 sensing element as an integrated unit.

4. A separate temperature transmitter or controller is required for signal conversion to standard outputs (e.g., 4-20mA).

5. Ensure thermowell material compatibility with process fluid composition and maximum operating temperature/pressure.
