delta V / delta V-P / delta P
Vacuum- / Pressure Switch digital for Gauge Pressure -1...0 / -1...+1 / 0...+10 bar
These electronic vacuum and pressure switches are trendsetting in view of technology and design. The series „delta“ is designed as an electronic switch with state-of-the-art technology and best price-performance ratio for usage in all kind of handling and many other industrial automation systems. The calibrated and temperature compensated sensor generates high-precision signals which are processed by an integrated circuit and transformed to two open collector output signals. Two switchpoints with the corresponding hysteresis and switching logic can be adjusted independent of each other.
The programming with the push buttons can be done with or without present pressure and a menu navigation facilitates this procedure. The sensor can be ordered with G-thread, NPT-thread or flange-adapter.
