PRESSURE MEASUREMENT EQUIPMENT
The Trafag product portfolio includes pressure switches, sometimes referred to as pressostats, as well as pressure transmitters.

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. Trafag also develops and manufactures products specifically to customer requirements. Please contact us for further details.

Advanced technology and precision manufacture guarantee faultless operation especially in applications where equipment features such as shock-resistance, vibration stability, electromagnetic compatibility, long-term stability or temperature insensibility are essential.

MECHANICAL PRESSURE SWITCHES (PRESSOSTATS)

The mechanical pressure switches from Trafag are outstanding for their compact design and high-precision micro-mechanics specially developed and manufactured by Trafag itself. These switches can be installed in any position and need no electric power, making them particularly versatile in application and fully site-independent.

Piston

For hydraulic applications with frequent switching and abrupt pressure changes.

Metal bellows

For fine control of pressure in liquid, vapor, and gaseous media.

Membrane

For the measurement of liquid, vapor, and gaseous media in applications with high switching frequency, abrupt pressure changes and where a high level of overpressure safety is required.

Housings

Aluminum housings, some epoxy coated, seawater resistant. With or without vision panel for switchpoint indicator.
