EJA130A differential pressure transmitter is a high static pressure differential pressure transmitter, which 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. EJA130A can also communicate with BRAIN hand manipulator, YHC4150, CENTUMCS, FieldMate, HART 375, and monitor them through them.
This guide describes the EJA130A high static pressure transmitter, its measurement principles, and key performance specifications such as pressure range, output signal, and power requirements. It also outlines the physical construction, material choices, and environmental limits for reliable operation.
The document includes detailed installation guidance, wiring diagrams, and supported communication protocols (BRAIN, HART, FF fieldbus, PROFIBUS). Certification information for explosion‑proof and intrinsic safety versions, as well as ordering codes and optional accessories, are also provided. This manual is written in Chinese.
| Measurement range | 1~100 kPa (100~10000 mmH2O) |
|---|---|
| Output signal | 4‑20 mA (linear or square‑root) |
| Power supply voltage | 10.5 V DC ~ 32 V DC (intrinsic safety version 10.5 V ~ 30 V DC) |
| Maximum working pressure | 32 MPa (≈ 3200 kgf/cm²) |
| Communication protocols | BRAIN, HART, FF fieldbus, PROFIBUS |
The transmitter outputs a 4‑20 mA current signal, selectable as linear or square‑root.
The device supports BRAIN, HART, FF fieldbus, and PROFIBUS protocols.
The transmitter operates from 10.5 V DC to 32 V DC (intrinsic‑safety version 10.5 V DC to 30 V DC).
The maximum working pressure is 32 MPa (approximately 14500 psi).
