TR 011 serie ATEX
zone II

Description and application

TR 011 serie ATEX
zone II

The temperature sensors serie TR 011 are designed to meet the requirements of EN 60 079-0 and EN 60 079-15 as amended by a valid certificate. They operate on the base of defined relationship between of sensing element resistance and 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.

  • Temperature sensors 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. certificate FTZU 07 ATEX 0143X

The sensors meet the IP 67 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 EN 60 079-0 as amended by a valid certificate.  

DECLARATION, CERTIFICATION, CALIBRATION

  • EU Declaration of Conformity – in accordance with Act 22/1997 Coll. on technical requirements on products as amended.
  • Calibration – The final metrological inspection – comparison with standards or working instruments – is carried out for all the products. Continuity of the standards and working measuring instruments is ensured within the meaning of the Section 5 of Act no.505/1990 on metrology. The manufacturer offers a possibility to supply the sensors calibrated in SENSIT s.r.o.’s laboratory (according to requirements of the EN ISO/IEC 17025 standard) or in an Accredited laboratory.
