Tube skin thermocouples

Due to its 8mm diameter sheath made from Hastelloy-X, the Fan Tip tube skin thermocouple can be bent and coiled to enable movement in both the horizontal and vertical axes. The 40mm end tip of the thermocouple is designed to be welded to the heater tubes on both sides, reducing the chances of the thermocouple breaking off whilst in service. The design is such that it can be used in all process heater applications. The length of the sheath can be increased by up to 30m and can be bent in a cold state to meet any fixture and exit point on the heater tube. Currently used by BP, Esso, Exxon Mobil and STATOIL, the thermocouple is suited for any process burning or heating applications, including hazardous area oil and gas, chemical and petrochemical installations. It is suitable for gas-fired, light fuel oil and heavy fuel oil heaters. The sheath can be supplied in either 316 stainless steel for gas-fired heaters, Hastelloy-X for light fuel oil, or dual sheath AR-161 version for arduous, heavy fuel oil applications.
