8303 DIFFERENTIAL PRESSURE TRANSMITTER

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.

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.

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.
