A. Product Overview

RTD Simplex 3 Wire Sensor with Plate Mounting Connection is used to measure the temperature of flat surfaces, plates, machinery bodies, heating equipment, and industrial process surfaces. The sensor is designed with a mounting plate that helps fix the RTD probe securely on the required surface.

This type of RTD sensor is useful where direct contact temperature measurement is required. The plate mounting design improves installation stability and ensures proper contact between the sensor and the surface. It is commonly used in industrial temperature monitoring, machine temperature checking, surface heating applications, and process equipment monitoring.

The sensor is available with a Pt100 simplex or duplex element, temperature range from -70 to 500°C, probe diameter of 5 mm or 6 mm, probe length from 25 mm to 200 mm, plate size of 50 mm by 20 mm, wire length from 0.5 meter to 10 meter, and 2 wire, 3 wire, or 4 wire configuration as per application requirement.

B. Working Principle

An RTD sensor works on the resistance temperature principle. The Pt100 element inside the sensor changes its electrical resistance according to temperature.

At 0°C, a Pt100 RTD element has a resistance of 100 ohms. When the surface temperature increases, the resistance of the Pt100 element also increases in a predictable manner. This resistance change is measured by a temperature indicator, controller, transmitter, PLC, or monitoring system and converted into a temperature reading.

In this plate mounting design, the RTD probe is placed in contact with the surface through the mounting arrangement. The plate helps hold the sensor firmly in position, allowing the sensing element to detect the surface temperature accurately. This makes it suitable for applications where surface temperature needs to be continuously monitored.

C. Why It Is Used

RTD Simplex 3 Wire Sensor with Plate Mounting Connection is used because many industrial applications require accurate surface temperature measurement without inserting the sensor into the process.

It is used for:

• Surface temperature measurement of flat and plate-like surfaces.
• Temperature monitoring of machinery and industrial equipment.
• Heating plate and hot surface temperature measurement.
• Process equipment temperature monitoring.
• Electrical and mechanical equipment temperature checking.
• Temperature feedback for controllers and indicators.
• Continuous temperature monitoring in industrial systems.

The 3 wire RTD configuration helps reduce lead wire resistance error and provides better accuracy compared to a basic 2 wire connection. The Pt100 element gives stable and repeatable temperature readings, making it suitable for industrial temperature measurement applications.
