| Application description |
The differential pressure measuring transducer Precont DD109B is a universal measuring transducer for small and medium pressures. By fitting it with various pressure sensors, measuring ranges between 2.5 and 100 mbar can be realised. Two connection cables are used for the power supply. The feed current is the measurement signal from 4...20 mA. The operating state is indicated with an LED.
