Yokogawa YOLPGAWA pressure transmitter EJX510B

Yokogawa YOLPGAWA pressure transmitter EJX510B

The sealing diaphragm of the diaphragm sealed remote pressure transmitter is used to prevent the medium in the pipeline from directly entering the pressure sensor component in the differential pressure transmitter. It is connected to the transmitter by a capillary filled with fluid. SC438W and SC438N (similar to EJA438W and EJA438N) diaphragm sealed pressure transmitters are used to measure the flow rate, liquid level, density, and differential pressure of liquids, gases, and vapors, and then output a 4-20mA DC signal corresponding to the measured differential pressure. It can also communicate with the manual operator and perform remote settings and monitoring
