Head Type Thermocouple Sensor

A. Product Overview

Head Type Thermocouple Sensor is a robust temperature sensing device designed for industrial temperature measurement applications. It consists of a thermocouple element or Pt100 element enclosed inside a metallic probe and protected by a terminal head. The head provides safe cable termination, mechanical protection and easy maintenance during installation.

This sensor is commonly used where stable, accurate and long-term temperature measurement is required. It is suitable for applications such as chemical processing, food and beverage production, HVAC systems, furnaces, boilers, ovens, tanks, pipelines, machinery and process heating equipment.

The sensor can be supplied in different types such as Pt100, J type and K type, with simplex and duplex options. Probe diameter, probe length, sheath material and connection type can be customized as per process requirement.

B. Working Principle

A head type thermocouple sensor works on the thermocouple principle. Two different metal wires are joined together at one end to form a measuring junction. When this junction is exposed to temperature, a small voltage is generated. This voltage changes according to the temperature and is converted into a temperature reading by a temperature indicator, controller, transmitter, PLC or data logger.

In Pt100 versions, the sensor works on the resistance temperature detector principle. The resistance of the Pt100 element changes with temperature. This change in resistance is measured by the instrument and converted into an accurate temperature value.

The protective sheath helps transfer heat from the process medium to the sensing element while protecting it from pressure, corrosion, vibration and mechanical damage. The head provides a secure enclosure for terminal wiring and allows easy connection with field cables.

C. Why It Is Used

Head Type Thermocouple Sensors are used because they provide reliable temperature measurement in demanding industrial environments. The protective head makes wiring simple and safe, while the metallic sheath protects the sensing element from harsh process conditions.

These sensors are preferred because they are easy to install, easy to replace and suitable for a wide temperature range. They can be customized based on temperature range, probe length, probe diameter, sheath material, mounting connection and head type.

They are useful in applications where surface-mounted or open-wire sensors are not suitable. The rigid probe design gives better durability and stable temperature measurement in tanks, pipelines, ovens, furnaces, process vessels and industrial machines.
