YOKOGAWA K9804JA Temperature Sensor | RTD Pt100, 3-Wire, 1/2" NPT, with Connection Head

YOKOGAWA K9804JA temperature sensor specifications. RTD Pt100 sensor assembly, 3-wire, 1/2" NPT, with aluminum connection head, general purpose.

Product Overview

The YOKOGAWA K9804JA is a general-purpose resistance temperature detector (RTD) sensor assembly designed for temperature measurement in industrial applications. It consists of a Pt100 sensor element housed in a protective thermowell with a 1/2" NPT threaded process connection. The assembly is terminated in a standard aluminum connection head, providing a protected junction for wiring to a temperature transmitter or indicator.

Key Features

  • Pt100, 3-Wire:​ Provides good accuracy with lead resistance compensation

  • Complete Ready-to-Install Assembly:​ Includes sensor, thermowell, and connection head

  • 1/2" NPT Process Connection:​ Standard industrial fitting for easy installation

  • Removable Sensor Insert:​ Allows for field replacement or calibration without process shutdown

  • Robust Thermowell:​ Protects the sensor element from harsh process conditions

  • Weatherproof Connection Head:​ Protects wiring terminals from environmental factors

  • Wide Temperature Range:​ Suitable for diverse industrial applications

  • Direct Compatibility:​ Can be connected to most standard temperature transmitters

Applications

  • Temperature measurement in pipes, tanks, and vessels

  • Process industries: chemical, petrochemical, oil & gas

  • Power generation (water, steam lines)

  • HVAC and refrigeration systems

  • General industrial temperature monitoring

Important Notes

  1. The exact insertion length, accuracy class (A/B), and other options are defined by the full model suffix.

  2. This assembly includes the thermowell; the RTD sensor inside is typically field-replaceable.

  3. A separate temperature transmitter or indicator is required to process the RTD signal into a standard output (4-20mA, etc.).

  4. Ensure the thermowell material (316 SS) is compatible with the process media.

  5. Proper installation torque and sealing are required for the threaded connection to prevent leaks.
