Products

We are specialists in position sensing, in other words feed back signal from a linear or rotary sensor. With our experience we will guide you to the best solution, no matter if you need some standard components from our stock or larger quantities of a customized sensor.

Process sensor / Pressure sensors / Pressure transmitters

Pressure transmitters

Trafag transmitters are used for the sensing of pressure and the transmission of pressure proportional electrical signals.

Options

Various process and electrical connections

Absolute/relative pressure measurement

Analogue/digital outputs

With/without bus interface

CE, EX or Marine Approvals

Trafag sensors are the basis of precise Pressure Transmitters.

Method of measuring

Thin film strain gauge. The force of the measured media deforms the thin film strain gauges thereby producing an electrical signal.

Steel sensors
Technology: Thin film on steel
Advantages:

Very good long-term stability

Resistant to high medium temperatures

All wetted parts are stainless steel (without additional material)

Very good overpressure resistance, ideal for nominal pressures up to 2000 bar

Ceramic Sensors
Technology: Thick film on ceramic
Advantages:

Resistant to aggressive media

Ideal for low pressure ranges

No filling with liquids behind the membrane

Excellent cost-performance ratio
