Content introduction
EJA110A transmitter, EJA110A differential pressure transmitter main, density and pressure, and then convert it into 4~20mA DC current signal output.
Product EJA series adopts monocrystalline silicon resonant sensor technology. Monocrystalline silicon has no hysteresis for changes in pressure or temperature and is a very ideal material. Monocrystalline silicon resonant sensors minimize the effects of overpressure, temperature changes and static pressure, providing unmatched long-term stability. - Small design The weight of this model is reduced to half of the original model due to the smaller packaging with the ASIC amplifier design and the miniaturization of the diaphragm construction and flanges. The ASIC design not only reduces the number of parts, but also improves the reliability of the amplifier. The Fieldbus is a two-way digital communication system, an innovative technology for configuring instrument control systems, and a promising replacement for the standard 4 to 20mA analog communication that is now widely used in field instruments.

When measuring liquid level with differential pressure transmitter. If the positive and negative ff chambers of the differential pressure transmitter are at the same level as the pressure taking points of the container. There is no need to migrate. And in practical application. For the installation position of the equipment and easy maintenance and other considerations. The measuring basin instrument may not always be at the same level as the pressure point: such as the measured medium is strongly corrosive or 0. The viscosity of the liquid. The medium cannot be directly introduced into the ff measuring instrument. A spacer tank must be installed. Use the spacer to transmit the pressure signal to prevent corrosion by the AuU instrument. At this time, it is necessary to examine the influence of the liquid column of the medium and the spacer on the reading of the pressure meter.
There are three main ways to install differential pressure transmitters to measure the maximum liquid level. To be able to correctly indicate the height of the liquid level. The differential pressure transmitter has to do some technical processing - namely migration. Migration can be divided into no migration, negative migration and positive migration.
