The here presented pressure transducers measure differences in pressure between the two connections of the measuring element. Pressure differences can be measured with respect to a reference pressure, such as atmospheric, or to the command variable of a regulation system. Equally, however, it is possible to measure pressure differences within systems that have a high static pressure. One practical example of this would be measuring a flow rate by measuring the pressure drop occurring across a metering diaphragm. The differential pressure transducers react in both directions – as are found, for instance, on double-acting hydraulic cylinders in material testing machines – and can handle liquid or gaseous media on both ports. Specific characteristics: – Available for line pressures up to 345 bar – Output available as ± 5 V or 4 … 20 mA – Suitable for liquid or gaseous media – Made of stainless steel, reliable, robust
