Description
The R-Type PVC/PVC Thermocouple Compensating Cable is designed for economical and dependable transmission of R-Type thermocouple signals between the sensing point and temperature measuring instruments. Since R-Type thermocouples are manufactured using Platinum-13% Rhodium/Platinum (Pt-13Rh/Pt) conductors, genuine extension-grade wiring can be expensive for long cable runs. This compensating cable uses specially selected substitute conductors that closely approximate the thermoelectric characteristics of R-Type thermocouples within a specified ambient temperature range, providing a practical and cost-effective solution for industrial temperature measurement systems.
Manufactured in a 2-core, 24 SWG construction, the cable features PVC insulation with a PVC outer sheath, offering good electrical insulation, flexibility, and mechanical protection for general industrial installations. Designed for ambient temperatures up to 105°C, it is suitable for connecting R-Type thermocouples to temperature controllers, PLCs, DCS systems, indicators, recorders, and industrial automation equipment.

FAQs
1. What is an R-Type PVC/PVC Compensating Cable?
An R-Type PVC/PVC Compensating Cable is designed to transmit the millivolt (mV) signal from an R-Type thermocouple to temperature controllers, PLCs, indicators, recorders, and other measuring instruments using specially selected compensating conductors that closely approximate the thermoelectric characteristics of the thermocouple within a specified ambient temperature range.
2. Why is a Compensating Cable used with R-Type Thermocouples?
R-Type Thermocouples use Platinum-Rhodium conductors, which are comparatively expensive. An R-Type Compensating Cable provides a more economical solution for transmitting thermocouple signals over suitable ambient temperature ranges while maintaining reliable measurement performance.
3. Where are R-Type Thermocouples typically used?
R-Type Thermocouples are widely used in glass manufacturing, ceramic processing, laboratories, heat treatment, furnaces, semiconductor processing, and other high-temperature industrial applications that require excellent measurement accuracy, long-term stability, and oxidation resistance.
