Pressure Transmitters for Demanding Industrial Applications
Based on either thin-film or micro-electro-mechanical system (MEMS) sensing technologies, these high performance devices have been introduced through our product range. They are optimized for use in demanding industrial environments - with industry leading resilience to shock, vibration and humidity, plus extensive temperature ranges, all being supported. Their elevated reliability characteristics are underlined by the fact that they are supplied with a 3-year warranty.
Benefiting from an innovative MEMS-based sensing arrangement, the members of the 3500 Series deliver a compelling combination of price and performance. They 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 and 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 technologically advanced devices are highly suited to refrigeration systems, medical instrumentation, heating ventilation air conditioning (HVAC) systems and gas analysis equipment. They have ultra-fast responsiveness (1 ms) and draw only 4.5 mA of current during operation (thereby keeping the related power consumption to a minimum).
Likewise the devices comprised within the P40-2 pressure transducer offering also have AISI 316L stainless steel construction and support measurement ranges that go from -125 … 125 mbar all the way up to -1 … 400 bar. These units come with a 4 … 20mA (2-wire) output signal and a high accuracy of 0.3%. Different process connection with an internal diaphragm is available. Alternatively a flush-mount design, which is highly suited to use with viscous and solids-bearing media, can be chosen.
A variety of compact designs and heavy duty housings are offered, thereby allowing these devices to be implemented in even the most space-constrained of application settings. All confirm to IP67 protection from liquid ingress, with the P40-2 being IP68 rated. Furthermore, they exhibit prolonged working lifespans (with above 100M operation cycles being expected).
