Yokogawa EJA118E Diaphragm Sealed Differential Pressure Transmitter
Yokogawa EJA118E -JH Diaphragm Sealed Differential Pressure Transmitter
The EJA118E Diaphragm Sealed Differential Pressure
Transmitters can be used to measure liquid, gas,
or steam flow, as well as liquid level, density, and
pressure.
- Power Supply Effects(Output signal code D and J)
±0.005 % per Volt (from 21.6 to 32 V DC, 350Ω) - Update Period “◊”
Differential pressure: 45 ms
Static pressure: 360 ms - Accuracy
Absolute Pressure
1 MPa or higher: ±0.5% of span
Less than 1 MPa: ±0.5%×(1 MPa/span) of span
Gauge Pressure Reference
Gauge pressure reference is 1013 hPa (1 atm)
Note: Gauge pressure variable is based on the above
fixed reference and thus subject to be affected by
the change of atomospheric pressure.
