Differential pressure transmitter is widely used in petroleum, chemical, electric power, metallurgy and other industries. The product is mainly used for the measurement of liquid, gas, steam pressure, differential pressure and negative pressure can also measure an opening or a pressure vessel with liquid level throttling device capable of measuring the liquid, gas or steam flow, and the measured parameters are converted into 4 ~ 20mA DC signal output, and passed to the two meter or adjusting unit for detection or control. The differential pressure transmitter is suitable for high temperature viscous medium and easy crystallization medium, containing solid particles or suspended solids precipitation medium, strong corrosive or toxic medium, can eliminate the pipe leakage pollution to the surrounding environment phenomenon; to be isolated by liquid, because the measurement signal is not stable, often need to supplement the tedious work isolation liquid.

Spot check of differential pressure transmitter:

The construction site of the fault, the vast majority of the use and installation methods are due to improper, summed up in several ways.

1 the first element (Kong Ban, remote measurement joints, etc.) plug or install the wrong form, the pressure point is not reasonable.

2 pressure pipe leakage or blockage, there are residual liquid gas pipe or gas filled tube with residual liquid, the transmitter flange in the process of deposition, the formation of a dead zone.

3 transmitter connection is not correct, the power supply voltage is too high or too low, indicating that the meter and the junction of the terminal connection is bad.

4 is not strictly in accordance with the technical requirements of the installation, installation and on-site environment does not meet the technical requirements.
