Fischer pressure transmitter Process technology 40 bar | DE58 Digital Differential Pressure Transmitter/ Switch

Display and switching device for measurement of differential pressures with mainly neutral liquid and gaseous media.
Areas of Application:
• Filling level measuring technology for technical gases
Design and Mode of Operation
The device is based on a robust and durable diaphragm measuring unit that is suitable for measuring overpressure, underpressure and differential
pressure. The pressures to be compared have an effect on a spring mounted measuring diaphragm. In case of equal pressure, the measuring dia-
phragm is in its idle state. In case of pressure difference, 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. This movement is transferred via atappet into the core of the inductive displacement
sensor. The linear movement of the core is proportional to the applied differential pressure. The electronics integrated into the device evaluate this
movement and transform it into signals on the display, switch contacts and an optional output signal.

Important features

maintenance-free through wear-free inductive pickup

switchable pressure units

Optional signal out with possibility of characteristic curve spread and reversal with any offset

Characteristic curve implementation via table with max.30 measuring points

Complete adjustment of all parameters and measuring point protocol possible from a PC using optional EU03 PC Adaptor

Typical applications

Filling level monitoring of tank containers for liquefied technical gases(N2,02,Ar and CO2)

Filling level monitoring of mini tank systems
