Introduction
The transmitter uses piezoresistive pressure sensor with isolated stainless steel diaphragm as signal sensing element, through automatic testing, laser trimming compensating zero and sensitivity in wider temperature range; the amplifier circuit is in stainless steel housing, transforming sensor signal into standard output signal. Through strict component making, semi-finished product and all-finished product testing and aging, the transmitter is stable and reliable, having excellent flexibility, sensitivity and diversity.
The product is widely used for pressure measure and control of petroleum, chemi-industry, metallurgy, power station and hydrology, etc.
