Yokogawa EJA530E Pressure Transmitter Inquiry Item

Details

This Yokogawa EJA530E is a direct-mounted gauge pressure transmitter of EJA-E series, adopting Yokogawa patented single crystal silicon resonant DPharp sensing technology. It measures gauge pressure of liquid, gas and steam, and converts pressure signal into standard 4~20mA with HART digital signal. It supports local parameter adjustment and remote configuration via HART/BRAIN protocol, built-in comprehensive self-diagnosis function. It features excellent long-term stability, 10-year stability up to ±0.1% URL, fast 90ms response time. Optional wetted parts material such as 316L, Hastelloy, Monel, suitable for various corrosive working conditions. Standard SIL2 safety certification and multiple explosion-proof certificates. Widely used in petrochemical, power, metallurgy and water treatment process pressure monitoring loops.
