Eja130a Pressure Transmitter
DESCRIPTION:
1.EJA130Abe used to measure liquid, gas, or steam flow as well as liquid level, density and pressure
2.unmatched long-term stability.
3.The EJA Series is available with BRAIN, HART, FOUNDATION™ fieldbus or PROFIBUS PA communication protocols.
4.The high performance differential pressure transmitter model EJA130A can be used to measure liquid, gas, or steam flow as well as liquid level, density and pressure.
It outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure.
FEATURES:
Excellent performance and stability
The EJA series uses a silicon resonant sensor formed from monocrystal silicon, a perfect material which has no hysteresis in pressure or temperature changes.
The sensor minimizes overpressure, temperature change, and static pressure effects, and thus offers unmatched long-term stability.
Compact and light-weight design
Half the weight of conventional models thanks to miniaturization of the casing with the amplifier ASIC, pressure cell structure, and flange. The ASIC uses the minimum
number of parts and improves the reliability of the amplifier.
Fieldbus communication capability
Fieldbus is a digital two-way communication system. It is a revolutionary technology for configuring instrumentation control systems and a promising successor to the standard 4 to 20 mA analog communication used in most field instruments today.
