Pressure Switch/Transmitter, Temperature Switch/Transmitter
The Trafag product portfolio includes pressure switches, pressure transmitters. Thermostats (switches) and temperature transmitters.
PRESSURE MEASUREMENT EQUIPMENT
Pressure switches
Trafag pressure switches are used when pressure has to be controlled or monitored via an electric on/off switching signal. These switches are available in various designs in respect of indication, switching capacity and approvals (CE, Ex, Shipbuilding, Railways) as well as the sensor system involved. In mechanical pressure switches, a pressure sensor actuates an electric micro switch. In electronic pressure switches, a pressure sensor signal controls relays or transistor outputs.
Pressure transmitters
Trafag pressure transmitters are used for the electronic measurement and evaluation of pressure values. They are available in many different versions with regard to pressure and electrical connections, measurement procedures, electric output signals, and approvals (CE, Ex, Shipbuilding, Railways). Two different sensor technologies are available, namely thin-film-on-steel (weld-sealed design without O-rings) and thick-film-on-ceramic.
TEMPERATURE MEASUREMENT EQUIPMENT
Thermostats
In the thermostat, a liquid enclosed in a sensor expands on exposure to heat and induces a bellows system. This in turn actuates a micro switch via a high-precision mechanism. The switch closes or opens a signal loop. Thermostats do not require any electrical energy supply. Thermostats from Trafag enjoy an outstanding reputation. Being fully maintenance-free, they can be in nonstop use for several decades without any loss of accuracy.
Temperature transmitter
Temperature transmitters are fitted with either Pt100 or Pt1000 sensors. Their change in resistance relative to temperature is transformed into an electric output signal or used to control relay contacts.
