This manual introduces the working principle, technical parameters, function parameters, use instructions, installation instructions of WIDEPLUS series pressure transmitters, and provides detailed zero and range adjustment instructions
The WIDEPLUS‑3000 is an intelligent pressure transmitter that converts pressure on a ceramic diaphragm into a standardized 4‑20 mA current signal. It incorporates a micro‑processor, linearization, temperature compensation and HART digital communication for remote configuration and diagnostics.
The manual provides detailed working principles, technical specifications, installation guidelines, explosion‑proof requirements, calibration procedures and software tools for device configuration. Safety precautions for hazardous areas and handling instructions are also included. This manual is written in Chinese.
| Measurement range | up to 60 MPa (relative pressure) |
|---|---|
| Output signal | 4‑20 mA current loop with optional HART digital overlay |
| Supply voltage | 24 VDC |
| Operating temperature (electronics) | -40 °C to +85 °C |
| Accuracy (temperature effect) | ±0.15 % FS per 10 K |
| Communication protocol | HART |
Press the “Zero” and “Range” buttons together for at least a few seconds to activate adjustment mode, then apply a known pressure and press the “Zero” button to set zero, followed by the “Range” button to set span. Power‑cycle the device to verify the new settings.
The transmitter uses the HART protocol for digital communication, superimposing a low‑level FSK signal on the 4‑20 mA loop.
It provides a two‑wire 4‑20 mA current loop, with an optional HART digital signal overlay for remote configuration and diagnostics.
The electronic circuitry operates from –40 °C up to +85 °C.
