pressure sensor
Pressure-sensor: build and function
Pressure sensors measure the pressure within a pipeline system. The pressure is then depicted optical or on a digital display, or transmitted by electronic signal to a Direct Digital Control (DDC). The DDC then processes the signal and depicts it graphically. There are two ways of measuring pressure: Typical gauge pressure measurement and absolute pressure measurement. Typical gauge pressure measurement measures pressure with regard to the ambient pressure. Absolute pressure measurement happens in a vacuum.
In order to measure the pressure, a strain gauge is mounted to a ceramic membrane, which measures the deflection, thereby determining changes in pressure. Ceramic membranes can withstand high pressures, are resistant to pressure surges, vacuum-tight, resistant to chemicals, corrosion and abrasion and insensitive to temperature surges. Also, they are very accurate and prove a high long-term stability and low temperature effect.
Pressure sensors play a crucial role in almost all pipeline systems, since these systems require constant monitoring and service. A pressure sensor is thus a very useful tool to monitor pressure within the system. Please find our wide selection of pressure sensors below.

A wide range of pressure sensors
Pressure sensors from NieRuf come with an external thread with ¼“ or ½“ connection. Depending on the model, they can withstand a pressure from 0 to 600 bar. The seal material is either FPM or EPDM. Stainless steel pressure sensors can be used with liquid or gaseous media. All pressure sensors from NieRuf have an accuracy deviation of less than 0,5%. The temperature range of all our pressure sensors can be found in the data sheets available for download on our website. To install a pressure sensor, the external thread of the sensor can be screwed onto a container or a pipeline system.
A ceramic membrane within the sensor measures the pressure and dispenses the pressure in milliampere through the electronic PNP output. You can also choose a pressure sensor with a digital display. Pressure sensors from NieRuf are high quality valves that can be used even in rough conditions. Neither shock- or vibration load, nor aggressive media or low temperatures harm our pressure sensors.
