Product details about "ATEX smooth tube probe IP67 -40...230°C"

The temperature sensors operate on the principle of defined dependence on the change of sensor property and on the temperature change. They are not capable of generating sparks, arcs or high surface temperatures. The temperature range for use in potentially explosive environments is limited by the insulation of the cable used and specified in the user manual - the specified measuring range must not be exceeded, even for a short period. The power cable can be fitted with an outer insulation made of PVC, silicone or PTFE (teflon) and can be shielded or unshielded. In accordance with standard EN 60 529, the sensors respond to IP 65 for the insulation of PTFE (Teflon) cables and to IP 67 for other power cables.

The temperature sensors are designed to operate in a chemically non-aggressive environment, the use must be chosen according to the temperature and the chemical resistance of the case and the power cable.

  • Probes temperature GTG8ExR Series - In combination with the thermowell or central support JTG8, supplied as accessories, the probes can be used to measure the temperature of gaseous and liquid substances in pipes or air conditioning pipes or separately to measure the temperature of solids.

DECLARATION, CERTIFICATION, CALIBRATION

The manufacturer issues a EU declaration of conformity. The declaration is established on the basis of the following certificates, issued by the Ostrava - Radvanice Institute for Physical and Technical Tests:

  • TG8Ex Appendix N ° 2 to the certificate number FTZÚ 07 ATEX 0142X

Calibration - The final metrological control - comparison with standards or working instruments - is carried out for all products. The continuity of standards and work measurement instruments is ensured within the meaning of article 5 of Law No. 505/1990 on metrology.
