Data Sheet Series 8201 Version H - 1

High Precision Pressure Transducer Series 8201 Version H Application 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 ■ Measuring ranges from 0 ... 30 bar to 0 ... 500 bar ■ Accuracy < 0.1 % ■ Output 0 ... 5 V, 0 ... 20 mA or 4 ... 20 mA available ■ Suitable for liquid and gaseous media ■ Can be used for dynamic and static measurements ■ Made of stainless steel, reliable and sturdy ■ Standardized sensitivity to 1.0 mV/V Description The medium reaches the interior of the measuring chamber through the pressure port. This is closed by a membrane which is welded on, and which represents the sensor element itself. The bending of this membrane increases in proportion to the applied pressure. Four strain gauges, interconnected as a Wheatstone bridge, are attached at the rear. The physical magnitude of pressure is converted by the wire strain gauges into a change in electrical resistance. The resulting output signal is standardized to 1.0 mV/V. The pressure is measured relative to the surrounding air pressure, and the space behind the membrane is therefore connected to the atmosphere through a small, protected opening in the housing. All the sensors can be supplied with an integrated amplifier having a voltage or current output. The input to the integrated amplifier is protected against reverse polarity connection, and the output is protected against overvoltage. Technical changes reserved.
