Pressure transmitters - Import export

The pressure transmitter illustrated here measures differences in pressure between the two connections of the measuring element. Pressure differences can be measured with respect to a reference pressure, such as atmosphere, or to the command variable of a regulation system. Equally, however, it is possible to measure pressure differences within systems that have a high static pressure. One practical example of this would be measuring a flow rate by determining the pressure drop occurring across a metering diaphragm. The differential pressure transmitter measures in both directions and can therefore, for instance, be used on double-acting hydraulic cylinders. Its construction permits it to be used with liquid or gaseous media. Venting holes simplify installation. The robust design and the use of stainless steel make it possible to use the pressure transmitter under tough operating conditions.

This transducer can be used anywhere thanks to its small size. Designed to work without a measuring chamber (uses a flush front diaphragm instead), this transducer is ideal for any measurements where the material to be measured may leave problematic residues. The range of suitable applications is even greater thanks to a choice of screw-on or weld-on adapters. Areas of use: Bottling plants, food industry Mixing facilities for the chemicals industry Pharmaceuticals Cosmetics industry Bioengineering These miniature pressure transducers are made entirely of titanium and therefore have outstanding resistance to corrosion. These convert the pressure-induced deflection of the diaphragm into a change in electrical resistance, which can be amplified, measured and processed by external electronic circuitry.

With its rugged housing and a stainless steel sensor element, the transducer is particularly robust and ideally suited to the harshest environments. This also means that the sensor can be installed anywhere with no effect on the measurement signal. The built-in instrumentation amplifier converts the sensor signals into noise-immune voltage signals or current signals that can be transmitted over relatively long distances. For high viscose materials, a front-level membrane M12 x 1 is available, and with this disruptive dead volumes can be expelled. The sensor has a small protected hole on the rear to allow measurement of atmospheric pressure (measurement type relative). For the absolute measurement option, the applied pressure is measured with respect to an enclosed vacuum. As an electrical connection, a DIN 43650A valve connector or an M12 x 1, 4-pin connection is available.

The sensor model 8228 with its measuring accuracy of 0.05% F.S. (for the measuring ranges ≤ 1 bar, the measuring accuracy is 0.1% F.S.) ideally suited as a reference sensor. The compact dimensions, the robust housing and the industrial-grade output signal result in a very wide range of applications. All components in contact with media are made of stainless steel. An integrated measuring amplifier converts the measuring signals directly into interference-free voltage signals or current signals that can be transmitted over long distances. With the „gage“ measurement type, the pressure measurement is carried out against the ambient pressure, the sensor has a bore that is protected against ambient influences to compensate for the ambient pressure. With the „Absolute“ measurement type, the applied pressure is measured against an enclosed vacuum; this measurement type is available from the measuring range 0 ... 250 mbar. The electrical connection is made via an M12 x 1 connector.
