ELHART TRE.C02 series temperature sensors are resistance temperature detectors (RTDs) designed to measure the temperature of solid, liquid, and gaseous media that are non-aggressive to the protective sheath materials and sensor cable. They are used in automatic control systems for various technological processes with secondary devices (measuring instruments, controllers, input/output modules, etc.).
TRE.C02 RTDs are manufactured with platinum sensing elements Pt100 or Pt1000 and have nominal static characteristics according to GOST 6651. Upon request, the sensors can be manufactured with a cable length of 2.5, 4, 6, 10, or 16 meters.
The protective sheath of the TRE.C02 series sensor is made of AISI 304 stainless steel. The cable has a silicone jacket and an extra wire to ground the shield.
