YOKOGAWA EJA 118 differential pressure transmitter
Features:
For EJA 118 differential pressure transmitter is a transmitter with integrated diaphragm seals, for EJA118W is with a pair of flush diaphragm seals, EJA 118N is with a pair of extended flush diaphragm seals and EJA118Y is with one flush diaphragm seal and one extended diaphragm seal; there are two types of flanges dimensions available with 3 inches (80mm) and 2 inches (50mm). Especially with following technical characters:
- Service: flow, differential pressure measurement of liquid, gas and steam and level, density, and pressure of liquid.
- Reference accuracy: 0.2 % of Span.
- Measuring range: there are two types of diaphragms are L, M. H respectively, applied to range from 1 kpa to 2.1bar.

Diaphragm seals are used to prevent process medium form entering directly into the pressure-sensing assembly of the differential pressure transmitter, they are connected to the transmitter using capillaries filled with fill fluid. Model EJA118W, EJA118N and EJA118Y Diaphragm Sealed Differential Pressure Transmitters can be used to measure liquid, gas, or steam flow, as well as liquid level, density, and pressure. They output a 4 to 20 mA DC signal corresponding to the measured differential pressure.
