SICK DHSB-T11 DustHunter T100 Dust Emission and Reception Unit

Product Description

SICK DHSB‑T11 is the transmitter‑receiver unit of DUSTHUNTER T100 series, manufactured by SICK‑Maihak Germany. It is the core optical probe for in‑situ dust concentration measurement inside flue gas ducts, working together with MCU control unit and reflector. Based on light‑transmission extinction principle, it continuously measures particulate / dust concentration for CEMS continuous emission monitoring systems.

Integrated optical transmitting and receiving assemblies with built‑in lens contamination monitoring. Purge‑air port accepts clean compressed air to prevent lens fouling. Fail‑safe shutter closes automatically under loss‑of‑air or power‑failure conditions to protect optical lenses. Designed for high‑temperature flue‑gas environment. Special cable connects to MCU main unit for signal processing, parameter configuration and data output. Corrosion‑resistant robust housing. OEM discontinued. Surplus‑new and tested‑refurbished units serve as critical optical replacement spares for legacy CEMS flue‑gas monitoring systems in power, metallurgy and waste‑to‑energy plantsSICK.
