Pressure transmitter - 8227

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.

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.

This torque sensor is qualified for static and dynamic measurements on non-rotary applications. Further the measurement of reaction torques on rotating machine parts is possible. Especially the torque sensors with flanges are preferred. They are mounted between motor and stator, e.g. in agitator drives. This enables a maintenancefree torque measurement. For individual measuring tasks the design of our torque sensors can be adapted to the customer’s installation conditions. More application examples: Test structures in the field of precision mechanics Determination of friction torques Acquisition of breakage moments on screw caps The design has been optimized regarding overall length, weight and volume, so that axial forces up to relatively high limit values and bending moments of up to 20 % of the measuring range have only a small effect to the influence of the measuring element.
