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 XL™ or HART® 275 host.
Daily maintenance :
careful cleaning;All sensors should be removed before using a wire brush or special compound to clean the extruder barrel.Both types of cleaning may cause damage to the sensor's vibrating membrane.When the barrel was heated, should also won't produce the wear sensor is removed and the use of the soft cloth to wipe the top of the sensor hole also needs a drilling machine with clean and clean up the guide bush.
Excellent performance and stability:
The EJA pressure transmitter series USES monocrystalline silicon resonant sensor technology.Monocrystalline silicon is an ideal material with no lag in pressure or temperature change.The monocrystalline silicon resonant sensor provides unparalleled long-term stability by minimizing the effects of overpressure, temperature change and static pressure.
Basic Information ：
EJA series: monocrystalline silicon sensor is a high quality electronic differential pressure transmitter for measuring liquid, gas or steam flow rate, liquid level, density and pressure.Static pressure can be displayed via an embedded display table or BRAIN protocol or HART communication protocol.It also has the features of quick response, remote setting of communication protocol, self-diagnosis function and optional high/low pressure alarm state output function.FF field general form available.The EJA family standard configuration has TUV certification.Suitable for SIL2 occasions except FF site general line.
