Differential pressure transducer for leak test

From differential pressure sensors, which are used in systems for the tightness or leakage examination, one expects the fact that they exhibit on the one hand smallest measuring range and withstands nevertheless high system printings. This demand following SETRA of system revised the receiver series of D239. With measuring range of � 60 Pa they are now appropriate e.g. for system printings up to 17 bar. The differential pressure transducers of the series of D239 offer an excellent linearity of 0,1% with measuring range between � 60 Pa and up to 70 kPa. The internal amplifier with temperature compensation is supplied with DC voltage between 22 � 30 V and supplies alternatively an output signal of 0 � 5 V or 4 � 20 mA. With an accuracy of up to 0,073%, a response time of < 100 ms and their high long-term stability are suitable these transducers for the employment in fastidious measuring and test systems.�
