RETRACTABLE - SKIN TYPE THERMOCOUPLE Tube Skin Thermocouples provide an efficient means of temperature measurement on the tube surface in Oil & Gas plants as well as Heater Tubes & Boiler tube temperature in Power Plants. Heat shields maybe added which prevent addition of external / ambient temperature on the junction thereby providing a more accurate temperature measurement.Expansion loops or coils are designed to avoid the effect of tube expansion which are subject to thermal growth. Mounting clamps are welded along the pipe for additional support. Tempsens provide custom build tube skin...

THERMOCOUPLE FOR SULPHUR RECOVERY UNIT (SRU) The thermocouple junction is isolated from the corrosive and invasive gases by using a constant air purge system across the junction. AIR purge system is kept at a pressure higher than the internal reactor pressure to avoid the entry of hazardous process gases inside the inner tube as the ceramic tube is the porous one. This is required to avoid the thermocouple oxidation and to get a fair life. Glass Sealing is done below the terminal block / on the inset top to avoid accident during the breakage of ceramic tube, as it acts as a pressure...

FCCU THERMOCOUPLE Fluid catalytic cracking (FCC) is one of the most important conversion processes used in petroleum refineries. It is widely used to convert the high-boiling, high-molecular weight hydro carbon fractions of petroleum crude oils into more valuable gasoline, olefin gases and other products. Cracking of petroleum hydrocarbons was originally done by thermal cracking. The purpose of Shear Valve is to close the valve manually & to cut the thermocouple probe, if the protection tube fails or get punctured inside the process which in turns will avoid any leakages. A boron coating...

COT THERMOWELL Erosive environments such as catalyst regeneration require the use of high hardness materials either via coated surface or solid construction. Stelite commonly used as a high hardness metal alloys for thermowell applications in Naphtha Cracker & FCC Unit. Tempsens can provide such thermowells or other similar thermowells to assure maximum service life and optimum performance.

BASICS OF WIRES & CABLES INSULATION Conductor Conductor Insulation Insulation refers to the layer of plastic, polymer or high temperature compound that is applied directly over the conductor. Tempsens provide variety of insulations along with wide temperature range from -260°C to 1200°C. Insulation Type Temperature range for various insulations are listed below : -73°C -73°C Fiber Glass Armouring Alumina Fibre Ceramic Fibre/Silica Inner Sheath Polyamide -267°C PTFE/PFA -267°C PEEK Outer Sheath SILICON ETFE SCREENING Screening is applied for magnetic and electrical protection. Generally two...

THERMOCOUPLE CABLES INSTRUMENTATION SIGNAL CABLES Thermocouple Cables are used to measure the temperature directly. Extension & Compensating wires are only used to extend a thermocouple signal from a sensor to instrument for readings. Instrumentation Signal Cables minimize noise and signal interference, delivering clean signals in harsh environments and general manufacturing operations. These cables are designed for use in communication and instrumentation.
