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.

Product programe

PRESSURE TRANSMITTERS

At the very heart of Trafag pressure transmitters are pressure sensors based on either thin-film-on-steel or thick-film-on-ceramic technology derived from own in-house development and production. This ensures that the pressure sensors and associated electronics are perfectly attuned to one another, a feature subsequently successfully confirmed through reliable function and long serviceable life.

Trafag is a technology pioneer in the miniaturization of rugged pressure transmitters.

Product programme

The following information provides an initial programme overview. The individual product features are not freely combinable with one another. Further information can be obtained by consulting Trafag`s product catalogs and data sheets.

Sensor technologies

Thin-film-on-steel technology:

Measurement is effected according to the strain gauge principle. Through the force effect of the sample medium, the strain gauge bridge is deformed, changing its electrical characteristics.

Features:

• Very good long-term stability
• Ability to endure elevated medium temperatures
• Completely weld-sealed sensor system made of stainless steel without O-rings
• Very high resistance to overpressure; ideal for rated values up to 2000 bar

Further information
» Technologies/Pressure Transmitter/Thin-film-on-steel

Thick-film-on-ceramic technology:

Measurement is effected according to the strain gauge principle. Through the force effect of the sample medium, the strain gauge bridge is deformed, changing its electrical characteristics.

Features:

• Resistant to aggressive media
• Ideal for low-pressure ranges
• Sealed with an O-ring

Further information
» Technologies/Pressure Transmitter/Thick-film-on-ceramic

Piezo-resistive systems:

If a force is applied to a silicone crystal, this will change its specific electrical resistivity. In the piezo-resistive process, pressure is indirectly transferred to the silicone crystal via a diaphragm backfilled with silicone oil.

Features:

• Ideal for very low pressure ranges
• Large degree of freedom in arrangement of pressure connections (e.g. front-flush diaphragms)
