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.
