EJCRLH Remote Seal Differential Pressure transmitter with double flange

EJCRLH Remote Seal Differential Pressure transmitter with double flange is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure. outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure.

Product Description

EJCRLH  Remote Seal Differential Pressure transmitter with double flange  

The remote seal differential pressure transmitter is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure. outputs a 4 to 20 mA DC 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.

Technical Parameter

EJCRLH  Remote Seal Differential Pressure transmitter with double flange   


Input

Measured value: Differential pressure, Level

Measuring range

Lower range value: -100% to +100% of the URL(continuously adjustable)

 

Output

Output signal

Two wire 4 to 20 mA DC output with digital communications, linear or square root programmable. HART FSK protocol are superimposed on the 4 to 20 mA signal. Output range: 3.9 mA to 20.5 mA.

Failure Alarm (the mode can be selected)

Low Mode (min): 3.7 mA, High Mode (max): 21 mA No Mode (hold): Keep the effective value before the fault. Note: The standard setting of failure alarm is High Mode.


Response Time

The amplifier damping constant is 0.1 sec; 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.
