Product Description

Yokogawa EJA220A Transmitter for Level Measurement

Yokogawa EJA Series transmitter firstly released in 1991, more than 4.5 million sets working worldwide. its DPharp digital sensor uses two single crystal silicon resonators vibrating at their natural frequencies. When pressure is applied, one of the resonators goes into tension, while the other goes into compression mode. It also has the unique ability to simultaneously measure static pressure and differential pressure.Additionally capsule and housing temperatures are also measured.

Two silicon sensor, one goes tension, the other goes compression

Yokogawa EJA220A Transmitter is flange mounted differential pressure transmitter used to measure liquid level, density and pressure, mainly use of measure level of tanks. There are three different type of flanges optional with size from 2" to 4"; outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure.

Important Note: CE/ATEX approval cancelled and C-tick replaced by RCM from Feb of 2016 due to not able to meet New NLF and electrical standard, EJA-A need to be replaced by EJX or EJA-E for Europe, Australia and New Zealand projects.
