Endevco has announced the 8511A series, a range of piezoresistive gauge pressure transducers designed for maximum reliability in extreme measurement environments.

Available in ranges of 5,000, 10,000 and 20,000psig, with a 3/8in mounting thread, Endevco 8511A series pressure sensors feature a four-arm piezoresistive strain-gauge bridge, diffused into a sculpted silicon diaphragm, for maximum sensitivity and wideband frequency response.

The transducers also feature self-contained full hybrid temperature compensation, providing stable performance over a wide temperature range of 0F to +200F (-18C to +93C).

In addition, these transducers are designed to survive 20,000g shock and minimum 2X burst pressure.

Endevco said that its 8511A series also offers excellent linearity, high shock resistance and high stability during thermal transients, making them suitable for use in studies of structural loading by shock waves resulting from explosive blasts; hydraulic or combustion system pulsation measurements; and automotive airbag testing.

For harsh environments where particle impingement is a concern, an optional protective screen and black silicone grease coating is available.

This further reduces photoflash sensitivity and provides an effective thermal barrier for short duration high temperature service.

Recommended accessories for use with the Endevco 8511A series include model 136 three-channel system, model 4430A signal conditioner, or model 4990A (Oasis), as signal conditioner and power supply.
