Differential pressure transmitter is a transmitter that measures the pressure difference between the two ends of the transmitter, and outputs a standard signal (such as 4-20mA, 0-5V). The difference between differential pressure transmitters and general pressure transmitters is that they have two pressure interfaces. Differential pressure transmitters are generally divided into positive pressure end and negative pressure end. Generally, the pressure at the positive pressure end of differential pressure transmitters should be greater than the pressure in the negative pressure section in order to measure.
Differential pressure transmitters are used to measure the liquid level and density of liquids, gases, and vapors
Measure the pressure and convert it into a current signal output of 4-20mA DC. JT-3051DP can also be operated by BRAIN manual operator or CENTUM CS/ μ XL or Hart 275 manual operators communicate with each other for setting and monitoring purposes. Differential pressure transmitter is used to prevent the medium in the pipeline from directly entering the transmitter, and the pressure sensing diaphragm is connected to the transmitter by a capillary filled with fluid. It is used to measure the liquid level, flow rate, and pressure of liquids, gases, or vapors, and then convert them into 4-20mA DC signal output. The cover of the picture shows a domestic brand 3051 differential pressure transmitter.
Differential pressure transmitters are suitable for the following measurement and control situations:
Viscous medium under high temperature
Easy to crystallize medium
Sedimentary media with solid particles or suspended solids
Strongly corrosive or highly toxic media
Can eliminate the occurrence of pressure pipe leakage and pollution to the surrounding environment; It is possible to avoid the tedious work of frequently supplementing isolation fluid due to the unstable measurement signal when using isolation fluid.
Continuous measurement interface and density
The remote transmission device can avoid the mixing of different instantaneous media, so that the measurement results truly reflect the actual situation of process changes.
