Oleodynamic and Pneumatic

It is an instrument suitable to measure low differential pressure also when there are high static pressures. Rather than exploit the dynamic pressure, as in instruments controlling circulation (fluxmeters), this product uses the difference between two opposed pressures, positive and negative (+ / -) read in two different points of the plant and separated by a membrane. The difference between the two forces determines the resulting displacement which is transferred to the microswitch. At the same time, this instrument is provided with a second relative pressure measurement element, which is enable when the plant pressure decreases below a set level.

These pressure switches are provided with two independents micro switches used to signalise the max or min pressure into equipment.

These pressure switches are provided with a second micro switch with manual restore device.

These pressure switches are provided with only one micro switch with manual restore device.

Protection degree IP54.

These pressure switches can be provided with a rubber cup (EPDM) to reach the protection degree IP45.
