EJXC80A, EJAC80E Differential / Gauge Pressure Diaphragm Seal System

JXC80A, EJAC80E
Diaphragm Seal System consists of gauge pressure or differential pressure transmitter with one or two diaphragm seal. Suitable for various kinds of pressure measurement.

Benefits

* High performance, high accuracy and high reliability.
* High temperature and high vacuum use (0.013 kPa abs~)
* Fast response: 200 ms

Compensating Capillary Design

Compensation capillary type has a compensating capillary to help balance the volume and temperature of the fill fluids between high and low pressure side capillaries. This solution reduces the influence of ambient temperature drift whether it is caused by
swings day-to-night, season-to-season, or shady-to-sunny.

This compensation capillary is attached to the high pressure side of the transmitter and runs along the low-pressure capillary. It is actually bundled to it. This allows the volume of fill fluid to be the same between the two sides of the transmitter and allows
for ambient temperature balance between them.

Ambient Temperature Drift

Ambient temperature is the temperature around the process. If the tank is located outdoors, the transmitter and capillary system could see temperature swings day-to-night, season-to-season, or even shady-to-sunny. This change in temperature affects the fill
fluid just like any liquid. The fluid contracts and expands within the capillary with the change. This can cause inaccuracy in the reading. The reading reflects a change in the fill fluid instead of an actual change in the level.
