Introduction:
WH-3051DP series differential pressure transmitter can be used in petrochemical, metallurgy, electric power, food, medicine, paper and textile industry.
It can be used to measure the differential pressure, pressure, liquid level, interface and density of the fluid.
The differential pressure transmitter converts the measured signal into 4-20mA DC, transmitted to display, calculation, regulation or control instruments, can form a variety of automatic control systems.
Applications：
WH-3051DP differential pressure transmitter can be used to measure the pressure, negative pressure and absolute pressure of gas, liquid and steam, and then convert them into 4 ~ 20mA, DC signal output.
Differential pressure transmitter can be used in petrochemical and power plant high-voltage devices.
Because of its high withstand pressure, and can withstand one-way overload pressure without being damaged, it can be reliably used for high-pressure system differential pressure measurement.
The micro -differential pressure transmitter can convert the micro -differential pressure to a 4-20mA. DC signal.
It uses a specially designed amplifier line board and a special temperature compensation process, with stable and reliable performance.
It can be used in the micro -pressure, primary and second air volume and air current loss detection of the furnace combustion chamber.
