different types of pressure sensors
Differential Pressure Transmitters for Level, Density of Liquids, Gases, and Steam
And pressure, and then convert it into a 4-20mA DC current signal output. The JT-3051DP can also communicate with each other via the BRAIN Communicator or the CENTUM CS/μXL or HART 275 Communicator, through which settings and monitoring can be performed.

The differential pressure transmitter is used to prevent the medium in the pipeline from directly entering the transmitter, and the pressure-filled membrane and the transmitter are connected by a fluid-filled capillary. It is used to measure the level, flow, and pressure of liquids, gases, or vapors, and then converts it to a 4-20 mA DC signal output. The cover for the domestic brand 3051 differential pressure transmitter.
Differential pressure transmitters are suitable for the following types of monitoring and control situations:
¡ñ viscous medium at high temperature
¡ñ Easy to crystallize media
¡ñ Precipitating medium with solid particles or suspended solids
¡ñstrongly corrosive or highly toxic media
It can eliminate the occurrence of the leakage of the pressure tube leakage surrounding the environment; can avoid the use of spacer liquid, because of the instability of the measurement signal, the need to frequently replenish the cumbersome work of the spacer fluid.
¡ñ Continuously and accurately measure the interface and density
The remote transmission device can avoid cross-mixing of different mediums in time, so that the measurement result truly reflects the actual situation of the process change.
¡ñ Occasionally high hygiene requirements
In the food, beverage, and pharmaceutical industries, it is not only required that the transmitter be in contact with the media in compliance with hygienic standards, but also that it should be easy to flush.
Prevent cross-contamination of different media.
