West Control Solutions’ latest pressure transmitter are based on either thin-film or micro-electro-mechanical system (MEMS) sensing technologies and are optimized for use in uncompromising industrial environments. Tailored for use in hydraulic systems and heavy machinery, the 3100 Series and 3200 Series provide measurement ranges up to 2,200 bar. They integrate a thermal compensation mechanism, which enhances overall accuracy and means that less accompanying electronics is required for signal conditioning. An extensive array of different electrical and pressure connection options are available, as well as a wide variety of electrical outputs.
Via a MEMS-based sensing arrangement, the 3500 Series components are capable of determining relatively small changes in pressure even at low pressure values, covering a range up to 40 bar with an accuracy of 0.2% full scale with minimal thermal drift. Each unit comprises a micro-machined silicon diaphragm with piezo-resistive elements situated at its edges. The cavity that separates the silicon diaphragm on the MEMS sensor component and the external diaphragm is filled with synthetic oil. Supplied in a small form factor with 316L stainless steel wetted parts, these devices are suited to refrigeration systems, medical instrumentation, heating ventilation air conditioning (HVAC) systems, and gas analysis equipment. They have a responsiveness of 1 ms and draw 4.5 mA of current during operation.
The P30-2 pressure transducers provide measurement ranges starting at -200 to 200 mbar and extend all the way up to -1 to 40 bar. Each device has an AISI 316L stainless steel housing that ensures operational robustness. These transducers can be specified with either a 0 to 10V (3-wire) or a 4 to 20 mA (2-wire) output configuration. They are optimized for installation in hydraulic systems, industrial pumps, compressed air apparatus, filling/weighing machines, level measurement equipment and packaging machines.
The P40-2 pressure transducers also have AISI 316L stainless steel construction and support measurement ranges that go from -125 to 125 mbar up to -1 to 400 bar. These units come with a 4 to 20 mA (2-wire) output signal and an accuracy of 0.3%.
