YOKOGAWA K9802MA Temperature Sensor | RTD Pt100, 2-Wire, 1/2" NPT, with Head, General Purpose

YOKOGAWA K9802MA temperature sensor specifications. RTD Pt100 sensor assembly, 2-wire, 1/2" NPT, with aluminum connection head, economical.

Product Overview

The YOKOGAWA K9802MA is an economical resistance temperature detector (RTD) sensor assembly designed for general-purpose temperature measurement. It features a Pt100 sensor in a simple 2-wire configuration, housed in a protective thermowell with a 1/2" NPT male threaded process connection. The assembly is completed with a standard aluminum connection head, providing a basic, cost-effective solution for non-critical temperature monitoring.

Technical Specifications

Key Features

• Pt100, 2-Wire:​ Simple and economical configuration

• Complete Assembly:​ Ready for installation with sensor, thermowell, and head

• 1/2" NPT Connection:​ Standard industrial fitting

• Removable Sensor:​ Allows for field replacement

• Durable Thermowell:​ Protects the sensor element

• Basic Connection Head:​ Provides terminal connection and environmental protection

• Cost-Effective:​ Ideal for applications where highest accuracy is not critical

• Wide Temperature Range:​ Suitable for many industrial processes

Applications

• General temperature monitoring in tanks and pipelines

• HVAC and building automation systems

• Non-critical process measurement

• Water treatment and heating systems

• Equipment temperature sensing where lead resistance error is acceptable

Important Notes

1. The 2-wire configuration is susceptible to errors from lead wire resistance; accuracy is lower than 3 or 4-wire RTDs. Best for short cable runs or non-critical applications.

2. A separate temperature transmitter or indicator is required.

3. Verify insertion length, thermowell rating, and material compatibility for the specific application.

4. This is an economical solution; for higher accuracy, consider a 3-wire or 4-wire RTD assembly.

5. Ensure the connected transmitter is configured for a 2-wire RTD input.
