Principle of Operation
EJCDP Differential Pressure Transmitter
The differential pressure transmitter includes two
functional units:
—Main unit
—Auxiliary Unit
The main unit includes a sensor and process
connection. The completely welded sensor module is a
twin-chamber system with an integral overload
diaphragm, an absolute pressure sensor, a
temperature sensor and the silicon differential pressure
sensor. The absolute pressure sensor, which is only
exposed to the pressure at the high pressure side, acts
as a reference value to compensate for the static
pressure. The temperature sensor as a temperature
compensated reference value to compensate for the
temperature drift.
RP1002/3 Gauge/Absolute Pressure
Transmitter
The gauge/absolute pressure transmitter includes two

EJCDP-A High Performance Differential
The high performance differential pressure
transmitter EJCDP-A is suitable to measure liquid,
gas, or steam flow as well as liquid level, density and
pressure. EJCDP-A outputs a 4~20 mADC signal
corresponding to the measured differential pressure.
Its highly accurate and stable sensor can also
measure the static pressure which can be shown on
the integral indicator or remotely monitored via
HART communications. Other key features include
quick response, remote set-up using communications,
self-diagnostics and optional status output for
pressure high/low alarm.

EJC Differential Pressure Level Transmitter General Specifications
EJCLT Differential Pressure Level
Transmitter
1 Application
The differential pressure level transmitter EJCLT is
as liquid level, density and pressure. EJCLT outputs
a 4~20mADC signal corresponding to the measured
differential pressure. Its highly accurate and stable
sensor can also measure the static pressure which
can be shown on the integral indicator or remotely
monitored via HART communications. Other key
features include quick response, remote set-up using
communications, self-diagnostics and optional status
output for pressure high/low alarm. The range Limits
is 0—1kPa ～ 2MPa, The flange’s working pressure
are 1.6/4MPa,6.4MPa,10MPa,150psi,300psi or
600psi.
2 Operation Theory and Structure
EJCLT differential pressure level transmitter is
composed of EJCLT series differential pressure
transmitter and the welding installation level flange.
The operation theory is the same as EJCLT series
differential pressure transmitter (consult EJCLT
series differential pressure transmitter general
specifications), Only the high pressure side of
pressure transmission path is different. The pressure
Loaded in the high side, pass from the isolation
diaphragm and silicone oil in the flange to the sensor.

and flange’s damping constant is 0.2~3 sec, it depends
on the range and range compression ratio. Amplifier
damping time constant is adjustable from 0.1 to 60 sec
by software and added to response time.
6 General conditions
6.1 Installation conditions
The transmitter can be directly flanged in any position.
Preferably in such a position that the process flange
axes are vertical. Deviations from this can cause a shift
in the zero, which can be corrected. The electronic
housing can be rotated through 360°and can be fixed
in any position. A stop prevents the housing being
turned too far.

EJCRH/RL Remote seal differential pressure transmitter General Specifications
EJCRH/RL Remote Seal Differential
1 Application
The remote seal differential pressure transmitter
EJCDP is suitable to measure liquid, gas, or steam
flow as well as liquid level, density and pressure.
EJCDP outputs a 4~20mADC signal corresponding to
the measured differential pressure. Its highly
accurate and stable sensor can also measure the
static pressure which can be shown on the integral
pressure high/low alarm. The range Limits is
0—1kPa～2MPa, The flange’s working pressure are
1.6/4MPa,6.4MPa,10MPa,150psi,300psi or 600psi.
EJCDP remote seal differential pressure transmitter
is composed of EJCDP series differential pressure
transmitter and the welding installation remote seal
flange. The operation theory is the same as EJCDP
series differential pressure transmitter (see EJCDP
series differential pressure transmitter general
specifications), Only the pressure transmission path
is different. The pressure loaded in the high or low
side, pass from the isolation diaphragm and silicone
oil in the flange to the sensor.

Note 1: Before flange sealing device selection, the selection of the EJCRN/S gauge/absolute pressure transmitter
should be completed, and selected R option in line 40 of the in EJCRN/S options table；
Note 2: The PTFE membrane(F4 membrane) posted on the diaphragm, it could be applied to the measurement of
negative pressure >50kPa, but it applies only to the flat level flange.

Note 3：Gauge/absolute pressure transmitter options
see the EJCRN/S Series transmitter general
Specifications;
Note 4：The minimum measuring range of the remote
seal gauge/absolute pressure transmitter should be
the larger value of the minimum range of table 1 and
table 2. The adjusted span must not be lower than the
minimum range.
Note 5：When measuring pressure <50kPa (absolute
pressure), it requires special handling during the
manufacturing process to ensure that performance.
