Introduction
The product uses piezoresistive OEM pressure sensor as sensing
element, which is accurate tested and laser trimmed to compensated
zero and sensitivity in wider temperature range. The amplifier
circuit transforms sensor signal into standard output signal.
Through long-term aging and stability testing, the whole product’s
performance is stable and reliable. The product is suitable for
rugged environment which needs zero elevation and range adjustment,
could be widely used for process control and pressure measure of
petroleum, chemi-industry, metallurgy, power station, textile
industry, building material, hydrology and environment control,
etc.
