PDM220 Compact Differential Pressure Sensor

Description

The EFE PDM220 compact differential pressure sensor provides an accurate pressure measurement of gas and liquids in ranges from 250mbar up to 600bar. Standard unamplified and amplified analogue outputs are available : mV/V, 0.5-4.5Vdc, 0-5Vdc and 2-wire 4 to 20mA current loop. They are suitable for uni or bi-directional measurement. Their construction being all stainless steel, they are compatible with most media, including corrosive fluids used in automotive and aerospace industries.

The EFE Engineering Department is responsible for designing all our sensors, from sensing elements to state of the art PCBs. To meet the customer’s high requirements, EFE decided very early on to develop its propriety sensing technology for pressure transducers. This technology, thin film, is manufactured mainly using a physical vapour deposit, and more precisely sputtering process on a metal diaphragm (stainless steel, titanium, inconel, hastelloy, etc.). This film is used by EFE is the only technology which does not require any intermediary between the sensing element and the fluid to be measured as with an oil separator for silicon based sensors or O-rings for ceramic technology.
