The sensor for detecting the temperature excess of DOTES is designed to control the ambient temperature in the places of installation of the technological equipment of the pumping stations of the main oil and gas pipelines, tank farms, loading racks and the issuance of an alarm signal that the temperature has reached the permissible temperature.

  • Gas pumping stations
  • Under the casings of gas turbines
  • Location of power equipment on ships, submarines, ships and offshore platforms
  • Explosive areas of premises and external installations, underground mine workings, mines and their ground structures, hazardous for mine gas and / or combustible dust

  • High measurement accuracy
  • Automatic reset is provided with a decrease in temperature.
  • The sensors are capable of continuous 24/7 operation
  • Resistance to increased ambient temperature equal to the maximum normal temperature
  • Vibration resistance

The sensors meet the requirements of GOST R 53325-2012. The sensor housing corresponds to GOST 14254 for IP67 group.
