PCE-28.MODBUS

Product catalog summary
Overview: The PCE-28.MODBUS is a smart pressure transmitter designed for industrial applications, featuring digital communication via Modbus RTU protocol. It is certified for intrinsic safety and explosion proof standards (ATEX, IECEx) and offers high accuracy of 0.1%.
Specifications:
  • Accuracy: ±0.1% of calibrated range
  • Long-term stability: Maintains accuracy for 3 years
  • Thermal error: < ±0.08% (FSO) / 10°C
  • Thermal compensation range: -25...80°C
  • Power supply: 4…28 V DC
  • Transmission range: 1200 m
  • Output: MODBUS RTU (optionally 4…20 mA)
  • Transmission speed: Up to 115200 bps
Measuring Ranges: The transmitter supports a wide range of pressure measurements from -100...100 mbar to 0...1000 bar, with specific overpressure limits for each range.
Materials: Wetted parts and diaphragms are made of 316L stainless steel, while the casing is 304 stainless steel (optional 316 stainless steel).
Installation: The transmitter is lightweight and can be installed without additional mounting brackets. For hot media, a siphon or impulse line is recommended. Electrical connections should use twisted cables.
Operating Modes: The device operates in two modes: configuration mode for settings and diagnostics, and Modbus mode for standard operation.
Ordering Information: The document provides detailed ordering codes for different configurations, including electrical connections, process connections, and additional options like marine certification and oxygen service.

Application The transmitters PCE-28.Modbus have two operating modes, configuration mode and Modbus mode. The configuration mode is used for changing settings and detailed diagnostics of the transmitter. In special version 4...20mA - the transmitter operates in a two-wire passive current loop system 4...20mA. The mode is activated after switching from Modbus mode to analog mode of operation It is required to connect the transmitter only with power wires. Digital output wires should be disconnected and protected. Installation The transmitter is not heavy, so it can be installed on the installation...
