Temperature detectors CTm-12, CTm-32, CTm-13, CTsp

The CTm-12, CTm-32, CTm13 and CTsp detectors are intended to control the temperature of the structure elements of band conveyors, i.e. of:
  • side plates of conveyor (CTm-12, CTm-13),
  • driving drum (CTm-32, CTsp)bearings
The detector CTm13 has a metal housing with two cable inlets, the CTm-12 and VTm-32 detectors have plastic housings, also with two cable inlets, while the CTsp detector is built without a housing - it has a conductor terminal. The above temperature detectors may be installed in rooms of grade "a", "b"and "c" of methane explosion hazard and of class "A" or "B" of coal dust explosion hazard. They are assigned for cooperation with spark-safe circuits.
