Digital remote sensor for measuring liquid levels
Yokogawa's EJXC40A digital remote sensor is a differential pressure transmitter that is equipped with two pressure sensors and is designed for process manufacturing applications such as oil and gas, petrochemical, and power generation.
Yokogawa's EJXC40A digital remote sensor is a differential pressure transmitter that is equipped with two pressure sensors that are connected with an electric cable and is designed to measure liquid levels in large tanks and large differential pressure with high-pressure fluids. It is designed for process manufacturing applications such as oil and gas, petrochemical, and power generation. The EJXC40A consists of two separate pressure sensors that are connected to each other by an electric cable. Based on the difference in pressures measured by each sensor, the EJXC40A determines the liquid level, flow rate, and pressure of liquids, gases, and steam.
The electric cable connecting the two pressure sensors can be up to 45 m in length, enabling the measurement of liquid levels with very large tanks and tall distillation columns. Since the two pressure sensors are connected only by an electric cable, their measurements are not influenced by changes in the ambient temperature. There is no need to correct for changes in temperature when performing fine differential pressure measurements with gas tanks and other applications. This ensures stable measurements. As the two pressure sensors can be set to measure different pressure ranges, the EJXC40A digital remote sensor can measure high differential pressures of up to 70 MPa, something that is difficult to do with a single sensor unit.
