EJA110E outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure. Its accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via BRAIN or HART communications.
Yokogawa EJA110E-JMB4G-U12EB/KF22/D1 Differential Pressure Transmitter
EJA110E features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure.All EJA-E series models in their standard configuration, with the exception of the Fieldbus, PROFIBUS and Low Power types, are certified as complying with SIL 2 for safety requirement.
Upper Range Value and Lower Range Value of the static pressure can be set in the range between 0 and Maximum Working Pressure(MWP). The upper range value must be greater than the lower range value. Minimum setting span is 0.5 MPa(73 psi). Measuring either the pressure of high pressure side or low pressure side is user-selectable.
Absolute Pressure 1 MPa or higher: ±0.5% of span
Less than 1 MPa: ±0.5%×(1 MPa/span) of span

MODEL AND SUFFIX CODES
The “►” marks indicate the most typical selection for each specification.
*1: HART 5 or HART 7 is selectable. Specify upon ordering.
*2: Users must consider the characteristics of selected wetted parts material and the influence of process fluids. The use of inappropriate materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage to plant facilities. It is also possible that the diaphragm itself can be damaged and that material from the broken diaphragm and the fill fluid can contaminate the user’s process fluids. Be very careful with highly corrosive process fluids such as hydrochloric acid, sulfuric acid, hydrogen sulfide, sodium hypochlorite, and high-temperature steam (150°C [302°F] or above).
*3: Only applicable for Wetted parts material code S.
*4: Not applicable for measurement span code F.
*5: Not applicable for electrical connection code 0, 5, 7, 9 and A. Content rate of copper in the material is 0.03% or less and content rate of iron is 0.15% or less.
*6: Not applicable for electrical connection code 0, 5, 7 and 9.
*7: Material of a blind plug is aluminum alloy or 304 SST.
*8: Not applicable for output signal code G.
*9: Not applicable for output signal code F
