Pressure Differential Transmitter
Differential pressure transmitters are generally divided into high-pressure ends(H) and low-pressure ends(L). Generally, the pressure at the high-pressure end of a differential pressure transmitter should be greater than the pressure at the low-pressure end before measurement can be made.
Pressure Differential Transmitters are different from ordinary pressure transmitters in that they have two pressure interfaces. Differential pressure transmitters( DPT) are generally divided into high-pressure ends(H) and low-pressure ends(L). Generally, the pressure at the high-pressure end of a differential pressure transmitter should be greater than the pressure at the low-pressure end before measurement can be made.
There are 2 serial core capacitors and an anti-interference circuit board inside the transmitter to prevent pulse interference and surges. Our self-developed differential pressure measuring transmitter updates the electronic components made of monocrystalline silicon and utilizes the piezoresistive effect of monocrystalline silicon, which results in higher range accuracy, stronger stability, and longer usability.
