SMA25K04DC series differential pressure transmitter
The SM25K04 high-precision differential pressure transmitter uses imported high-precision and high-stability chips in its detection section. It is packaged using a stainless steel or aluminum alloy shell and stress isolation technology. The sensitive chip is bonded from a silicon diaphragm with a diffused silicon resistor bridge and a ceramic substrate with impedance adjustment capabilities. It can be widely used in industrial fields or laboratories for the measurement and control of gas differential pressure and flow.
