DE38_LED Differential Pressure Transmitter

Digital differential pressure transmitter / switch with colour change DE38_LED is a diaphragm measuring device and is suitable for measuring over-pressure, under-pressure and differential pressure in neutral liquid and gaseous media. The switching device is based on a robust and durable diaphragm measuring unit. The pressures to be compared have an effect on a spring mounted measuring diaphragm that is in an idle state when the pressure is equalised. The force acting on the measuring diaphragm causes it to be moved towards the side of the lower pressure until the spring forces compensate this force. The movement of the diaphragm is transferred via a tappet into the core of the inductive displacement sensor. The electronics integrated into the device evaluate this movement and transform it into signals on the display, switch contacts and optionally into an analogue output signal. The can be dampened, spread, inverted and transformed via a table function even if it is non-linear.
