Pressure sensors with ceramic measuring cell The devices with a ceramic measuring cell are designed for the highest demands with nominal pressures from -1 to 600 bar by means of an optimized support in the process sensor. These sensors are extremely robust against mechanical influences and operate completely wear and tear and fatigue-free. The resulting long-term stability ensures safe operation and reliable measurement results over 100 million pressure cycles. Pressure sensors with stainless steel measuring cell The devices with strain gauges in thick-film technology on a stainless steel measuring cell are characterized by a very compact and robust design. The seal-free welded stainless steel measuring cell ensures a high degree of safety. The three to thirty-fold burst pressure, depending on the selected measuring range of the device, and the equally high shock and vibration resistance underline the maximum operational reliability of ifm pressure sensors with stainless steel measuring cell. Pressure sensors with silicon measuring cell The devices with piezoresistive silicon measuring cell are in no way inferior to sensors with the ceramic measuring cell used up to now in terms of accuracy. Thanks to their design, they allow differential pressure measurements without a second connected pressure transducer. System solutions In addition to the large product range of pressure sensors ifm also offers special and reliable system solutions. Special devices, based on our proven pressure sensors, offer even greater application and usage possibilities. The PC-based communication and software solutions make the handling of ifm pressure sensors even more convenient. Level sensors In addition to the conventional pressure sensors for hydrostatic level measurement ifm now also offers level sensors for level measurement. This design opens up numerous new areas of application, for example level measurement in wells, flowing waters, boreholes and sewage plants. The high accuracy and long-term stability ensure long-term operation in these applications. All components of the level probe that come into contact with the medium are made of stainless steel (1.4571).

The piezoresistive relative sensor recognizes even smallest pressure changes in the volume flow rate and changes it into electrical signals. Evaluation units like flowscreen can analyse these signals.

he coating of the flow channel – which is out of a perfluorelastomere – guarantees very high chemical resistance. This means, the sensor is suitable for nearly all materials in the fields of medical technology, bio technology or also electronics.

Pressure sensors (also known as pressure cans, pressure load cells or pressure transmitters) differ, apart from the design and the output signal, mainly in the type of reference pressure for pressure measurement: here there are pressure sensors for relative pressure, absolute pressure and differential pressure transducers.
In a pressure sensor for relative pressure, the back of the sensor element is exposed to the air pressure surrounding us. In a typical setup, a small tube leads from the back of the sensor to the plug or through the connection cable. These pressure sensors have the advantage that fluctuations in air pressure are not reflected in a fluctuation of the output signal.
The pressure sensor for absolute pressure has a small chamber on the back of the sensor membrane which is completely evacuated, i.e. the chamber is 0 bar absolute. These pressure sensors show the current air pressure, which is typically between 950 and 1050 mbar, as long as no measuring pressure is present. Changes in air pressure (e.g. due to a rising high or low) therefore lead to a change in the measuring signal without changing the actual pressure value. A special type of absolute pressure sensors are barometers, which measure the ambient air pressure very precisely. A special form of the pressure sensor is the so called sealed gauge version. Here, the reference chamber is sealed tightly at approx. 1000 mbar. These pressure sensors are mainly used for measuring ranges >10 bar. Closing the reference chamber prevents, for example, aggressive gases from entering the reference chamber and causing corrosion.
Another special form of pressure sensors are so-called differential pressure sensors or pressure transducers. Here the back of the sensor membrane is mechanically constructed in such a way that it can be used as an independent pressure connection for pressure measurement. A pressure sensor (pressure cell or pressure load cell) in this version therefore indicates zero at the same pressure on the input and reference sides. Differential pressure sensors differ substantially in their mechanical construction. Here there are simple designs which, for example, only allow dry gases for the reference side or also high-quality pressure transmitters which allow an overload (even on one side) of more than 200 bar at a small nominal measuring range of 35 mbar.
Pressure transmitters often have a very robust mechanical design and have a 4...20 mA output signal which is common in process measurement technology.

TURCK pressure sensors detect relative or absolute pressures in liquids and gases. The PS series offers pressure sensors with display and different output variants (switching and analog output) and communication via IO-Link. The PT series includes pressure sensors without display with analog output for media temperatures down to -125 °C. The PC series offers communication via IO-Link. The PK series sensors are pressure sensors with display especially for pneumatic and vacuum applications.

The PS300 sensors are available in the connection variants G1/4", 1/4" NPT and R1/4" with switching contacts and analog outputs for current or voltage. Metal-supported sealing rings ensure a reliable process connection. In addition to the new IO-Link communication standard, the sensor series also supports the VDMA menu structure on request.

The high-precision silicon resonant pressure sensor innovatively adopts a dual-resonator, monolithic beam-membrane integrated design. When pressure acts on the pressure sensitive membrane, it causes deformation in the two "H" type resonators fixed at both ends of the membrane. This deformation leads to a change in the resonators' natural frequencies.
Controlled by a signal conditioning circuit, a stable closed-loop self-excited system is formed, resulting in stable dual-frequency signal outputs. By substituting these frequencies into a formula for calculation, the measured pressure can be obtained.
