| 详细介绍： HYDAC压力传感器
Electronic pressure sensors are used for recording pressures in fluid technology systems. Functionality and form of execution are determined by the respective utilisation conditions. In order to fulfil these requirements, HYDAC offers a comprehensive programme from miniature pressure transducers to customer-specific multiple pressure switches.
Electronic pressure transducers record the measured pressure variable and convert it into a proportional output signal.
Electronic pressure switches record the measured pressure variable, process it and output a switching signal in accordance with the presetting.
HYDAC压力传感器
Electronic pressure switches offer a multitude of advantages in comparison with mechanical pressure switches and contact manometers. They convince though greater accuracy, freedom from wear, long-term stability, simpler operation and the high number of switching cycles, among other things.
