YOKOGAWA K9194XA Temperature Sensor | RTD Pt100, 3-Wire, 1/2" NPT, with Connection Head

YOKOGAWA K9194XA temperature sensor specifications. RTD Pt100 sensor assembly, 3-wire, 1/2" NPT, with aluminum connection head, general industrial use.

Product Overview

The YOKOGAWA K9194XA is a general-purpose resistance temperature detector (RTD) sensor assembly designed for reliable temperature measurement in industrial processes. It consists of a Pt100 sensor element in a 3-wire configuration, housed within a protective thermowell featuring a 1/2" NPT male threaded process connection. The assembly is completed with a standard aluminum connection head, providing a secure and protected termination point for field wiring.

Important Notes

1. The specific insertion length is defined by the model suffix; verify the required length for the application.

2. This is a sensor assembly; a separate temperature transmitter or indicator is required for signal processing and display.

3. The 3-wire configuration helps minimize errors from lead resistance; ensure correct wiring to the transmitter.

4. Verify the pressure-temperature rating of the thermowell for the specific service conditions.

5. Material compatibility (316 SS) with the process fluid should be confirmed.
