Yokogawa EJA118E/Z Diaphragm Sealed Differential Pressure Transmitter (Inner Diaphragm type)
Yokogawa EJA118E/Z -DM Diaphragm Sealed Differential Pressure Transmitter (Inner Diaphragm type)
The EJA118E/Z Diaphragm Sealed Differential Pressure
Transmitters (Inner Diaphragm type) 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, 350 Ω) - 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.
