EMC-hardened RS485 humidity/temperature transmitter for data centers and industrial rooms.

ModelDB5301
SKUDABECO-DB5301
CategoryHumidity & Pressure

Key Features

  • Swiss-imported digital humidity sensing chip
  • Humidity range 0-100% RH; temperature -40 to 120°C (probe dependent)
  • RS485 Modbus RTU, up to 1200 m communication distance
  • EMC protection: surge, EFT burst immunity, electromagnetic isolation
  • Multiple installation types: wall, duct, remote probe, flange, thread, clip, insertion
  • Optional large LCD display
  • Customizable outputs: dew point, absolute humidity, mixing ratio
  • Optional IP67 protection rating

Overview

The DABECO DB5301 is a high-precision temperature and humidity transmitter built for data centers, communication rooms, and industrial environments, using a Swiss-imported digital humidity sensing chip for accurate, stable measurement. Advanced EMC protection — surge immunity, electrical fast transient burst immunity, and electromagnetic isolation — keeps it reliable in electrically noisy environments, with RS485 Modbus RTU communication and wall-mounted, duct-mounted, remote-probe, flange, thread, clip, or insertion installation options.

Working Principle

A digital humidity sensing chip paired with a Pt1000 RTD measures relative humidity and temperature at the sensor head, transmitting readings over RS485 using Modbus RTU. Multiple units can be networked on the same bus (addresses 1-255) for centralized monitoring across a facility, with optional customization to output dew point, absolute humidity, or mixing ratio.

Benefits

  • EMC hardening suited to electrically noisy data-center and industrial environments
  • Multi-point RS485 networking for centralized facility monitoring
  • Multiple mounting formats cover duct, wall, and remote-probe installs from one platform
  • Long-term stability (<1% RH/year, <0.1°C/year) reduces recalibration frequency
