DB43‑DB481 High Temperature Humidity Meter – Setting & Energy Saving System

Application cases

Where is the hidden “electricity cost killer” for textile mill owners? The heat setting machine is always at the top of the list. Operating at 180℃–220℃ for fabric drying and setting, it consumes nearly 30% of the plant’s total energy. Worse still, high‑temperature exhaust carries oil mist, fiber dust, and corrosive gases. Conventional humidity meters often break down: probes coated by oil, sensors corroded by acid, sampling ports blocked by dust. Frequent shutdowns for cleaning and maintenance become routine.

Now, the DB481 Anti‑Pollution High Temperature Humidity Meter is engineered for these harsh conditions! Equipped with double dust filtration, 316L stainless steel probe, and IP65 protection, it operates reliably in exhaust ducts up to 250℃ (customizable to 400℃).

With ±2% F.S. accuracy and T90 < 20s fast response, it stabilizes humidity measurement and improves waste heat recovery efficiency by up to 15%. Paired with the DB43 controller, it supports automatic purge cleaning to cut maintenance frequency by half. It also features auto/manual calibration, data logging, historical curve viewing, limit alarm output, 4.3-inch touch screen, RS485 Modbus, and 4–20mA for full system integration.

This heavy‑duty “workhorse in harsh exhaust” turns energy waste into cost savings. Lower power bills, less downtime, higher productivity — the DB43‑DB481 is your ideal solution for textile setting energy efficiency and reliable process monitoring.
