Working Principle
1 Differential Pressure Transmitter(DP)
Chart 1 Differential Pressure Transmitter (DP)
Differential pressure transmitter includes two functional units:
※ Main unit
※ Auxiliary unit
Main unit includes sensor and process connection, working principle as followed:
The sensor module uses whole welded technology, in which has a compact overload diaphragm, a differential
pressure sensor and a temperature sensor. The temperature is taken as a reference for temperature compensation.
- 5 -
The positive end of the differential pressure sensor is connected with high pressure chamber of sensor capsule; the
negative end is connected with low pressure chamber of sensor capsule. Through the isolated diaphragm and filling
liquid, the differential pressure is transmitted to silicon die in the inner of differential pressure sensor, which makes the
resistor of sensor die change. So the detection system outputs different voltage. The output voltage is in proportion to
the pressure variation, and then it is transmitted to standard output by adapter and amplifier.
2 Gauge Pressure Transmitter (EJCGP )
Absolute Pressure Transmitter (EJCAP )
Chart 2 Gauge (GP)pressure transmitter/Absolute(AP)pressure transmitter
Pressure transmitter includes two functional units:
※ Main unit
※ Auxiliary unit
Main unit includes sensor and process connection, working principle as followed:
Through corrugated, isolated diaphragm and filling oil, process media is pressurized to diaphragm of pressure
sensor. The other end of pressure sensor diaphragm is connected to the air (for gauge measurement) or vacuum(for
absolute measurement). In such way, it makes the resistor of sensor die change so that the detection system outputs
different voltage. The output voltage is in proportion to the pressure variation, and then it is transmitted to standard
output by adapter and amplifier.

Chart 3 Differential Gauge Pressure Transmitter(DGP)/Differential Absolute Pressure Transmitter(DAP)
Differential pressure transmitter includes two functional units:
※ Main unit
※ Auxiliary unit
Main unit includes sensor and process connection, working principle as followed:
The sensor module uses whole welded technology, in which has a pressure sensor and a temperature sensor.
The pressure sensor is used for gauge or absolute pressure measurement. The temperature is taken as a reference
for temperature compensation. The measured end of pressure sensor is connected to working chamber of sensor
capsule; the negative end is connected to reference chamber of sensor capsule and open to air. In such way, the
pressure difference is transmitted to silicon die of pressure sensor, which makes the resistor of sensor die change. So
the detection system outputs different voltage. The output voltage is in proportion to the pressure variation, and then it
is transmitted to standard output by adapter and amplifier.
-DP Differential Pressure Transmitter
-DP Differential Pressure Transmitter is used for level, density, pressure and
flow measurement of liquid, gas and steam. Then it will outputs 4mA~20mA DC HART signal
and also it could be connected to RST375 hand communicator or RSM100 Modem to do the
specification setting and process control.

Pressure range limit
The pressure is adjustable within the upper and lower limit.
It is recommended to choose the range code with the lowest pressure range proportion to optimize the
performance specification.
- 24 -
Zero setting
The zero and pressure range could be adjust to any value within the measured rang in the table, only the
calibrated range≥Min. Range is valid.
Mounting position effect
The change of mounting position parallel to diaphragm could not influence the zero drift. If the angle between
mounting position and diaphragm is over 90° , the zero drift is <0.4kPa which could be calibrated by zero setting. No
effect on pressure range.
Output
2- wire, 4mA~20mA DC, HART communication protocol, linearity or square root output optional.
Output signal limit: Imin=3.9mA,Imax=20.5mA
Alarm Current
Low alarm mode(min.): 3.7mA
High alarm mode(max.): 21mA
No alarm mode(holding): holding the active current value before failure
Standard alarm current mode: High alarm mode
Response time
The damping constant of amplifier parts is 0.1s, time constant of sensor is 0.1s~1.6s, which is depended on the
pressure range and pressure range proportion. The additional adjustable time constant is 0.1s~60s.
