Different types of pressure transmitters exist: differential pressure transmitter for measuring a pressure difference ΔP but also a relative or absolute pressure transmitter. For more specific applications, it will be necessary to use: a differential pressure transmitter to correct variations of pressure and temperature of a gas two transmitters for the same differential pressure flow element to increase the measuring range For more details on these cases, please see the Frequently Asked Questions tab on this page.

The annular chamber (carrier rings) is proposed for orifice plates, for venturis and for nozzles. It has several advantages: it favors the circulation of the fluid over the complete circumference of the pipework and offers a more stable and precise averaged pressure; in the case of the orifice plate, it also allows to change only the plate in case of maintenance or change of process compared to a monoblock where the complete system must be changed. This type of mounting is particularly recommended for pipe diameters smaller than DN50.

The 3D diaphragm pressure gauge is used to measure the pressure of neutral and aggressive media. The manometer is hermetically separated from the media by a diaphragm made of PTFE-TFM 1700 to protect it against the corrosive affects of the media. The pressure is measured through a buffer fluid that transfers the pressure onto the measuring chamber of the manometer. The large surface of the diaphragm ensures high-precision measurement results.

The F02 has been designed for application in systems which require a pressure transmitter with a Performance Level PL d or a Safety Integrity Level of SIL 2. It has a thin-film measurement cell made from stainless steel which is welded together with the pressure sensor and thus guarantees high media compatibility. It is available within pressures from 10 to 1200 bar. The output signal is made available at two outputs in parallel, whereby the second output represents an inverted signal. Users can select between a ratiometric and an 4-20-mA output in three-wire technology. The permitted media temperature range extends from -40…+125 °C. The total accuracy in the compensated range of 0…+80 °C lies at <= 1 % FS. The possible flexibility during integration into an existing machine is ensured through the provision of a multitude of available pressure connections as well as the small construction. The electrical contact takes place via a 5-pole M12 connector. The F02 also has E1 approval.

The M01 series has been especially designed for applications in adverse ambient conditions in the same way value is placed on high resistance to aggressive media. Furthermore, the modular principle permits many combinations of pressure connection, pressure range, output signal and connector, so that the right sensor can be found for most applications. For pressure ranges from 10 to 2000 bar, which are frequently required for use on mobile machines, welded stainless steel measurement cells are used which are suitable for media temperatures from −40 to +150 °C. Depending on the type of measurement cell and the material coming into contact with the media, the M01 is resistant to aggressive/non-aggressive gases and liquids. On request, versions in 316L design for use in hydrogen pressure measurements are available. In addition to CE and UL certificates, every M01 product with a 1.4542 stainless steel measurement cell possesses an E1 approval verifying its suitability for use in vehicles.

The F01 is also available with one switching and one analog output. The current output is read back by the F01 to ensure the output signal is emitted correctly. To be able to use the F01 in many applications, users can select different pressure connections. The electrical contact takes place via a 5-pole M12 connector. Through the calibration of the transmitter via temperature, a total accuracy of 1 % FS can be achieved within a range of 0...80 °C. The maximum media temperature totals +125 °C. The stainless steel parts coming into contact with media guarantee maximum media compatibility in combination with the welded thin-film measurement cell.

Instantaneous values and saved data can still be read if the battery is flat, because power is supplied by the reader.

Checking is better: with our compact measuring unit, you can detect the wrong brush pressure and correct it immediately. The wrong brush pressure is often the cause of serious problems in motors and generators.

Compact, light, and easy to handle: with our brush-pressure unit, you can measure the carbon-brush pressure precisely and in a matter of seconds. The large display provides an immediate reading from 0.1 to 50 N.

The HPX high-pressure calibrator is a high-precision calibration instrument for pressures between 0 bar and 700 bar.
