Function
The pressures act on two pressure chambers separated by an elastic diaphragm. Different pressures in the chambers cause an axial deflection of the diaphragm against a pressure spring which is proportional to the pressure. This is transmitted to the movement via a rod. The differential pressure is directly indicated by a pointer. The diaphragm is held by metallic supports at both sides providing an overpressure safety of up to 25 bar.

Operating temperature range
Medium: Tmax = +60 °C
Ambient: Tmin = -20 °C
Tmax = +60 °C

Temperature performance
Indication error when the temperature of the measuring element deviates from 20 °C: rising temp. approx. ±0.5 %/10 K falling temp. approx.±0.5 %/10 K percentage of full scale value

Protection IP 54 (EN 60529)
