Thread-In RTD Sensor with Cable | Pt100 Temperature Probe

A. Product Overview

The Thread-In RTD Sensor is used for measuring temperature in liquids and gases where a strong and reliable process connection is required. This sensor is suitable for industrial applications where the probe needs to be securely installed into equipment, tanks, pipelines, vessels or machinery.

It is commonly used in air conditioning, refrigeration technology, heater systems, furnace applications, apparatus construction, machinery, plant equipment and industrial process control.

This sensor is available with Pt100 simplex or duplex element, making it suitable for both standard temperature measurement and applications where dual sensing or backup measurement is required.

Key Specifications

B. Working Principle

The Thread-In RTD Sensor works on the resistance temperature detector principle. The Pt100 element inside the probe changes its electrical resistance when temperature changes.

When the probe tip comes in contact with liquid, gas or the process area, the Pt100 element senses the temperature. This resistance signal is then sent through the cable to a temperature controller, indicator, transmitter, PLC or monitoring system. The connected device converts the resistance value into a temperature reading.

The thread connection helps the sensor remain fixed in position and creates a reliable sealing arrangement for vacuum and overpressure applications.

C. Why It Is Used

The Thread-In RTD Sensor is used when accurate temperature measurement, strong mounting and reliable sealing are required. It is preferred in applications where the sensor must be fitted directly into a machine, pipe, vessel, tank or process equipment.

It is especially useful in liquid and gas temperature measurement because the thread connection helps prevent loose fitting and supports stable measurement in industrial conditions.
