It is designed for differential measurements where high static pressure is present on both sides. The measuring cell is a monolithic piece of 17-4 PH stainless steel, fully laser-welded and resin-potted. The sensitivity can be adjusted by ±75%, allowing one sensor to cover multiple ranges. The price depends on the measuring range and sensitivity.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNominal pressure selectable:\u003c\/b\u003e Differential pressure 0.5, 1, 2.5, 5, 10 and 20 bar (zero point at atmospheric pressure).
