The reliability and safety of a sensor is extremely important, particularly in high-pressure applications such as water-jet cutting equipment and hydraulic circuits. The dynamic loading encountered in these applications requires the use of sensors that are specially adapted for high pressure ranges. It is exactly these tough requirements that are satisfied by the model number 8221 sensor. With dynamic pressures, for example, an unlimited number of measurements can be taken if the pressure lies within the range from 0 ... 70% full scale.
The strong construction allows liquid or gaseous media to be measured in the laboratory, production department or in hydraulic applications.
Range of applications:
The monolithic sensor membrane guarantees a high level of precision, reliability and safety, since the medium does not come into any contact with welded seams. Great emphasis has been placed on safety in the mechanical design. It is fitted with relief holes, which permit the measurement of static and dynamic pressures, even under unfavorable environmental conditions.
In order to facilitate the exchange of the sensors without having to recalibrate the following electronics, the sensitivity of the high-pressure sensor is standardized at 1.0 mV/V. The sensor is fitted with an integrated shunt resistor to enable easy calibration or checking of the subsequent electronics.
In combination with the option of an integrated amplifier (0 ... 10 V, 0 ... 5 V and 4 ... 20 mA) the new, innovative function for digital calibration can be used: All that is necessary is to touch the marked surface of the sensor with the enclosed magnetic pen.
