Overview
The EJA430E high-performance differential pressure transmitter adopts monocrystalline silicon resonant sensor technology, which is suitable for measuring the flow rate, liquid level, density, and pressure of liquids, gases, or vapors. The EJA110E converts measured differential pressure into a 4-20mADC current signal output, which can measure, display, or remotely monitor static pressure. It has functions such as fast response, remote setting, and self diagnosis.

Damping time constant:
The damping time constant of the amplifier can be adjusted within the range of 0.00~100.00 seconds through software, and the response time increases accordingly.
Refresh time:
Differential pressure: 45ms
Static pressure: 360ms
Zero adjustment:
Within the upper and lower limits of the membrane box range, the zero point can be adjusted arbitrarily.
External zeroing:
It can be continuously zeroed within the range, with a resolution of 0.01%. The range can be adjusted using the range setting switch on the meter head.
