SPRING LOADED THERMOCOUPLE CONFIGURATIONS THERMOWELL & REPLACEABLE INSERT II 2G/D Ex e TCRE/WE C20 C21 C26-2 C26-2 1
FEATURES TECHNICAL SPECIFICATION ASSEMBLY The industrial spring loaded configuration guarantees a positive contact between the sensing part of the temperature probe and the bottom of the thermowell, thus reducing the response time. All assemblies offer a variety of protection heads to meet environmental and size requirements of most applications. All assemblies available with single/double and triple hot junction Connection head Aluminium With external earth terminal Ambient temperature range: -40/+100 C IP 6X protection degree (body cover) with oil-proof rubber O-ring, when used with crect cable gland Epoxy finish; colour grey RAL9002 Cover: hinged type screw type with chain with 1 two cable entries Protection tube : stainless steel SS316L 316TI / Hastelloy C22-C276 and many others on request. Standard diameter: 12x1.5 mm Other: examples 10x1.5 / 6x1 n: tube : 3 mm / n: pipe: 5 mm Tolerances :all dimensions +/- 1 mm ATEX : code A G=gas D=Dust IECEx : code I G=gas D=Dust Technical specification sens insert High quality Thermocouple element with MgO mineral insulated metal sheathed cable, providing excellent stability and reproducibility. The unique properties make this basic element ideally suited f a wide range of applications. The Thermocouple is bendable over the total length, except on the tip over +/-10 mm.

F duplex and triplex : all circuits isolated from each other and from the sheath. Common isolated (CI) Multiple hot junctions joined to one hot junction electrically isolated from and shielded by the sheath. Grounded (G) Hot junction welded to the sheath. Note: F thermocouples with diameters less than 3 mm OD, the insulation resistance test at 500 VAC can not be achieved. It will be done at lower voltage, depending on the diameter. F grounded thermocouples this test can not be done. Therefe extra precautions shall be taken as these thermocouples are not free from earth ( not at requested 500VAC), which means suitable barriers have to be used.
