The electronic differential pressure transmitter,
also called DP sensor ,
is one of the most widely used instruments in industrial production.
There are also many physical parameters measured by it,
such as pressure, liquid level, and flow rate,
which can be obtained by it,
which is of great significance for industrial production.
As the detection and transformation part of the process control system,
the differential pressure transmitter converts the process parameters such as differential pressure (pressure),
flow rate and liquid level of liquid, gas or steam into a unified standard signal
(such as DC 4mA ~ 20mA current).

These signals are used as input signals for display instruments, operators,
and regulators to enable continuous detection and automatic control of the production process.

12.The pressure sensor directly senses the measured liquid level pressure, and it is not affected by the foaming and deposition of the medium
13.Easy to install, debug and use
1. Electronic differential pressure transmitters eliminate the problems，
that arise in traditional differential pressure measurements and have higher process suitability and reliability.
2. Based on HART communication, it measures the differential pressure, top pressure and sensor temperature of the same system, thus providing multivariable level measurement.
3. It also provides uninterrupted identification of the health of the entire system through HART diagnostics.
