THERMOCOUPLE EXTENSION / COMPENSATING CABLES

Precision and Reliability in Temperature Measurement: Sundan Thermocouple Cables.

Sundan Technologies offers thermocouple extension and compensating cables used for precise temperature measurement and control in industrial processes. These cables have conductors with similar thermo-electric properties as the thermocouples they connect to, ensuring accurate temperature readings. They meet various international standards like IS:8784, ANSI-MC 96.1, BS, ENI, and DIN.

Introduction

These cables can also be termed as Instrumentation Cables as they are used for process temperature measurement. The construction is similar to paired instrumentation cable but the conductor material is different. Thermocouples are used in processes to sense temperature and is connected to the pyrometers for indication and control.

The thermocouple and pyrometers are electrically conducted by thermocouple extension/compensating cables. The conductors used for these cables are required to have similar thermo-electric (emf) properties as that of the thermocouple used for sensing the temperature. The cables are manufactured as per IS:8784, ANSI-MC 96. 1, B.S., ENI, DIN and customers’ specification.
