Differential pressure transmitter YOKOGAWA Electric Corporation has announced the release for sale in Europe of the EJXC40A digital remote sensor, a newly developed DPharp EJX ® series differential pressure transmitter. Equipped with two pressure sensors, connected with an electric cable, the EJXC40A offers performance in the measurement of liquid levels in large tanks and large differential pressure with high-pressure fluids. The new addition to the DPharp EJX series will meet a wide range of customer needs. Differential pressure/pressure trans- mitters are used in the oil, petrochemical and chemical industries in applications such as oil and gas wells. By measuring the difference in pressure at two points in a tank or pipe, the transmitters can calculate the level, flow rate and den- sity of liquids, gases and steam. In ap- plications where a tank liquid or gas or a pipe fluid cannot be introduced into the pressure-receiving unit (diaphragm) of a transmitter, diaphragm-sealed differen- tial pressure transmitters are used. A transmitter of this type is connected to two separate pressure-receiving units by a capillary tube that is filled with silicone oil or some other fluid. Although such transmitters are capable of precisely measuring high-pressure fluids with a high resolution, they are not suitable for use with large tanks because of limitations in the allowable length of the capillary tubes. In addition, they are not ideal for fine differential pressure measurement because the fluids in

the capillary tubes are susceptible to changes in the ambient temperature. The EJXC40A consists of two sepa- rate pressure sensors that are connect- ed 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 45m 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. The two pressure sensors can be set to measure different pressure ranges, allowing the EJXC40A digital remote sensor to measure high differential pressures of up to 70 MPa – something that is difficult to achieve with a single- sensor unit.
