Yokogawa EJA110A Differential Pressure Transmitter
Original New Yokogawa Eja110A Differential Pressure Transmitter
Product Description
YOKOGAWA Differential Pressure Transmitter EJA110A
The high performance differential pressure transmitter model EJA110A can be used to measure liquid, gas, or steam flow as well as liquid level, density and pressure. It outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure.
Model EJA110A also features remote setup and monitoring through communications with the BRAIN™terminal and CENTUM CS™ or µXL™ or HART® 275 hos

The EJA-A series is Yokogawa's most successful pressure transmitter line. First released in 1991, it continues to offer high performance and high reliability for any application. With an installed base of over 4-1/2 million EJA-A transmitters worldwide, it has a proven track record that makes it a true industry workhorse.
The EJA110A is the Traditional-mount Differential Pressure Transmitters in the series.
Applications
Flow Measurement: It can be used to measure the flow rate of liquids, gases, and steam. By measuring the differential pressure across a flow - measuring element such as an orifice plate or venturi tube, the flow rate can be calculated. It is widely used in industries such as oil & gas, power, and specialty & fine chemical.
Liquid Level Measurement: The EJA110A is suitable for measuring the liquid level in tanks. By measuring the differential pressure between the top and bottom of the tank, the liquid level can be determined, which is applicable in chemical, water & wastewater treatment industries.
Density Measurement: It can also be used to measure the density of liquids. The differential pressure measured is related to the density of the liquid, which is useful in some chemical and industrial processes where density monitoring is crucial.
