The temperature sensors are designed to meet the requirements of EN 60079- 15:2006 standard. They operate on the base of defi ned relationship between change of sensing element resistance and change of temperature. They are not able to form sparkles, electric arcs or high surface temperatures. The sensors that are identified on the type label by II 3G Ex nA II ty code can be utilised in explosion endangered rooms, device group II, zone 2. The operating temperature range for using them in zone 2 is identified by the lead-in cable type. These limits must not be exceeded even for a short time - see Y in the specifications. According to the design of the sensors there are the following variants:
Serie TG8 - the sensing element is located in the stainless steel tube with diameter 5,7 mm as a standard, the length of the case can be selected in the range 40 to 500 mm optionally. The stainless steel thermowell JTG8 can be delivered as an accessory.
Serie TR 011 - the sensing element is located in the stainless steel case, the part of which is the screwing enabling the direct assembly in tubing etc. Diameter of the case and the type of thread is taken up by customer, the length of the case can be selected in the range 40 to 500 mm optionally.
The sensors meet the IP67 ingress protection requirements according to en 60 529 standard. The sensors are designed to be operated in chemically non-aggressive environment. They can be used only for fix installations of group II and user must provide fixed clamping of the cable in the distance max. 100 to 300 mm from the sensor case according to par. A.2.3.2 EN 60079-0 ed.2.
Used sensing elements: Ni 1000/5000, Ni 1000/6180, Ni 891, Pt 100/3850, Pt 500/3850, Pt 1000/3850, thermistor NTC 20kΩ.
