Sensor Standard

OMEGA’s PX4600 Series consists of accurate, highly reliable pressure transducers suitable for printed circuit board mounting. The small size and light weight of the PX4600 tranducers make them ideal for tough vibration and shock environments. The sensor is a small silicon chip with 4 diffused silicon strain gages. Laser-trimmed resistors provide excellent temperature compensation from

-54 to 121ºC (-65 to 250°F), and users can adjust zero balance

and span to tight tolerances. The unusually high performance of this transducer comes from a 4-activearm bridge sensor using a micromachined diffused silicon diaphragm and proprietary thin-film media and dielectric isolation barriers. See next page for specifications.
