Description

Wide range of applications

The pressure transmitter model GPE81 has been designed for all fields of industrial pressure measurement.

Typical applications are in mechanical engineering, plant construction and automation industry as well as in the refrigeration and air conditioning industry.

Reliable measurement technology

Pressure ranges from 0 ... 1 bar up to 0 ... 1000 bar cover the measuring ranges of the most applications. The sensors with high accuracy, long-term stability and repeatability, have been well established in industrial pressure measurement for decades. Depending on the pressure range, the suitable sensor, either piezoresistive or metallic thin film, will be utilized.

Reliable signal acquisition

With various standard output signals like 4 ... 20 mA (2wire), or 0 ... 10 V, 1 ... 5 V and 1 ... 6 V (3-wire), the transmitter can be easily integrated into different systems.

RFI/EMI-characteristics according to EN 61 326 guarantee signal integrity even under difficult environmental conditions.

Interesting price/performance ratio

The excellent performance characteristics and the good price/performance ratio of the make it the perfect choice for applications with medium and large volumes.
