Series QND

Car,Building Purpose Pressure Transducer

QND sensing element has excellent temperature properties by adopting a self temperature compensation foil strain gauge.The size is small and price is low for vehicles and heavy machinery use.In addition, a diaphragm and a pressure port are welded together for the prevention of leakage.It is also durable to an instant over pressure and builds an inner amplifier to interface with various kinds of controllers.
