EJA130A high static pressure differential pressure transmitter is used to measure the liquid level, density and pressure of liquid, gas or steam, and then convert it into a 4~20mADC current signal output.
This manual describes the EJA130A high static pressure transmitter, its measurement principles and output options. It includes performance data, accuracy, pressure range, and environmental limits, as well as the supported communication protocols such as BRAIN, HART, FF fieldbus and PROFIBUS.
Installation guidance covers mounting orientations, wiring diagrams, power supply requirements, and safety certifications. The document also lists optional configurations, certification codes for explosion‑proof and intrinsically safe versions, and ordering information. This manual is written in Chinese.
