Characteristics of 4 groups of instrument cables for the oil and gas industry
Instrumentation cables and compensation cables are used in the oil and gas industry as well as in the chemical, pharmaceutical, and F&B industries.
1. HELUKABEL expands its portfolio in the oil and gas industry
At HELUKABEL, we are expanding into new markets with Instrumentation Cables and Thermocouple Extension Cables for applications in the oil and gas sector as well as the chemical, pharmaceutical, and food industries.
1.1 Instrumentation cables
Instrumentation Cables are used wherever processes need to be controlled and monitored. For example, this type of cable transmits measurement data on temperature, pressure, or flow rate and is used to control valves, temperature controllers, and signal lights. Particularly in onshore plants such as oil refineries or chemical plants, the distance between the control room and the components requiring control signals (such as valves, control lights, or sensors) can be very long. To ensure error-free signal transmission over these long distances, our instrumentation signal cables are an ideal solution for you.
1.2 Thermocouple extension cables
Commonly used in temperature measurement and control systems, especially for connecting to temperature sensors (thermocouples) to transmit temperature measurement signals to controllers or monitoring devices.
