8221 - HIGH PRESSURE TRANSDUCER

High-precision pressure sensors from the 8201 series provide exact measurements while exhibiting very little sensitivity to mechanical stresses. Their application therefore goes well beyond research and development laboratories. They are also outstandingly suited to industrial use in quality assurance or for measurement and control tasks in production. Their robust mechanical and electrical construction guarantees good long-term stability and high reliability, while being resistant to aggressive media – which can be measured in liquid or gaseous states. The structure of the sensors includes no mechanical moving parts, which is why they show so little sensitivity to impact and vibration. The pressure sensors can be configured with options to suit the user. Standard types are available ex-stock, and customized customer versions can also be provided. Aeras of application are: —Research and developmemt —Test rigs —Mechanical engineering —Plant control and monitoring

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.

Model number 8201 precision pressure sensors are robust, economical, and are available in standard measuring ranges. Their good technical specification and high reliability make them optimum for measuring pressure in all fields of machine construction, process technology, as well as in measurement and control technology. The pressure transducers are easy to handle and immune to shock loads and vibrations as they are designed without moving parts. All pressure transducers without an internal amplifier have a standardized output signal of 1.0 mV/V. This enables the user to change a transducer in a measuring chain as liked without following readjustment of the electronic. Customized designs are available on request. Aeras of application are: —Hydraulic or pneumatic machines —Mechanical engineering —Plant control and monitoring The measuring element of the precision pressure transducer consists of a diaphragm.

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.
