Esdun Industrial 
The EJXC40A Digital Remote Sensor (DRS) transmitter connects two pressure sensors, the primary sensor (for high-pressure side) and secondary sensor (for low-pressure side) with DRS dedicated communication cable to measure differential pressure. The DP is transmitted via a 4 to 20 mA analog signal. EJXC40A is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure.
About OpreX
OpreX is the comprehensive brand for Yokogawa’s industrial automation (IA) and control business and stands for excellence in the related technology and solutions. It consists of categories and families under each category. This product belongs to the OpreX Field Instruments family that is aligned under the OpreX Measurement category.
Differential Pressure (DP)
The transmitter outputs differential pressure, using the two transmitters of same model and capsule for primary (high-pressure side) and secondary (low-pressure side) pressure sensors.
