Available in the 1, 2, 5 and15 psig low pressure ranges with a 300mV full-scale output and up to 20X minimum burst pressure (1 and 2 psig versions), these transducers’ output is three times that of any other industry pressure transducer at comparable ranges, claims the manufacturer. The Endevco 8507C features an active four-arm strain gauge bridge, diffused into a sculptured silicon diaphragm, for maximum sensitivity and wideband frequency response. The 2.34mm cylindrical housing of the Endevco 8507C is designed for space constrained installations, or for those which do not require threaded mounting. Its small size even permits flush mounting on curved surfaces.

Self-contained hybrid temperature compensation provides stable performance over an operating temperature range of -18 to +93°C, with excellent thermal transient measurement stability. The transducers also feature linear performance to 3X range and high shock resistance, along with the highest available output for size ratio.

In addition to piezoresistive pressure transducers, Meggitt also offers a full range of Endevco prepolarized condenser measurement microphones, in free-field, pressure, low-cost array and random incidence types, which may be used to meet IEC and ANSI standards. Models may be purchased as stand-alone units or in precalibrated microphone and low-noise preamplifier combinations with iTEDS onboard memory storage (per IEEE 1451.4).
