Fischer pressure transmitter Building technology 16 bar | DS31
Applications
Differential pressure switch for positive / negative gauge pressure or differential pressure of neutral media such as industrial water, water for heating systems, neutral gases and oils. It is suitable for on/off control due to the continuously adjustable switching point between 10% and 100% of the measuring range.
Main Features
• high repeatability of switchingpoints
• long service life
• high overpressure protection
Principles of Operation
These pressure switches are based on a rugged and uncomplicated diaphragm movement. They are suitable for monitoring positive / negative gauge and differential
pressure. The operating principle of the system is identical in all three cases. The monitored pressure or differential pressure creates an unbalanced force on the diaphragm. This force moves the diaphragm system against the force of the range selector springs. A tappet, which is mounted on the diaphragm, actuates the microswitch. The setpoint can be adjusted by a scaled hand-wheel.
