Overview

This high-precision humidity transmitter, the DABECO DB43, is designed specifically for harsh industrial environments. It boasts exceptional high-temperature tolerance, robust dust and corrosion protection, and a wealth of intelligent features. It is suitable for precise measurement and automated control of humidity in processes such as drying rooms, setting machines, and steamers, across a variety of industrial sectors including wood, new energy, papermaking, chemicals, rubber, fiber, tobacco, and ceramics processing. The DB43 provides reliable measurement support and professional solutions for extreme operating conditions such as low temperature, high humidity, and high dust levels.

Working Principle

A limiting-current-method sensing element mounted via direct insertion into the duct measures gas humidity (as %VOL or g/kg) and, alongside it, oxygen content, at flue gas temperatures up to 400°C. Readings and configuration are managed through a built-in 4.3-inch touch screen, with results transmitted via 4-20mA analog and RS485 Modbus RTU digital outputs.

Applications

Benefits

400°C rating and anti-pollution protection suit the harshest high-temperature, high-dust industrial drying processes
Combined humidity + O2 measurement supports advanced combustion/process efficiency control
Touchscreen interface simplifies on-site configuration and monitoring versus button-only displays
Dual output (4-20mA + Modbus RTU) integrates with both analog loops and digital automation systems
