Profile: Revti Electronics Industries is a manufacturer and exporter of thermocouples. We are an ISO 9001 certified company. Our products include thermowells, industrial heaters, heat tracing cables, power cables, LT cables, compensating cables, and PVC cables. We also offer fiber glass cables, silk cables, silicon cables, and ceramic cables. These cables are available in temperature range of -60°C to 1500°C. Thermocouple extension wire is used to extend the signal from a probe to instrumentation such as controllers or recording devices. Often times, multi pair thermocouple extension cables are preferred in these applications. Extension wire is designated by an "X" after the ANSI thermocouple type- i.e. BX, EX, JX,KX, SX, TX.
