Tanaka - Model DDM-HAL2 -Dust Density Monitor
DDM-HAL2 is a dust monilor designed for stationary sources such as industrial boilers and incinerators, and shipboard boilers to monitor dusi in real time. Air pollution lias increased environmental and public health risks, and the government air pollution control law is gelling tougher. To comply with the law it is important to continuously manage the dust monitoring data along with the isokinetic sampling method Q\S method) which happens every few months. DDM-HAL2 is a dust density monitor designed for small scale incineration facilities and for shipboard boilers.
The advantages of DDM-UAL2 are (he high performance, the low cost, the durability, the easy installation, the easy and low maintenance, and the automatic span calibration — there is no need to remove the dust detector from the installation while calibrating, DDM-HAL2 equips automatic calibration function. It is high sensitive and can measure low to high density dust including PM25 up to 0.03 micro meter dust particles in real time. The dust density data from DDM-HAL2 can be used as an evidence when you need it. Although use of a dust detector is not required by law. The vision of DDM-HAL2 Ls to help the small facilities exhausting flue gas to build environmental sustainable business and to achieve environmental CSR. but also to increase the productivity and decrease the cost of the productivity. Tanaka Electric Lab dust monitor products comply with Japanese Industrial Standard Z8852 (JISZ8852). which is for a method of automatic dust monitoring.
- High sensitive optical sensor: It can measure up to 0.03 micro meter dust particles.
- Accurate and reliable dust detection: Dust concentration in laminar flow in duct and chimney is unevenly distributed in the flue gas. The Tanaka Electric Lab. light scattering method optical sensor can detect dust particles in larger area inside duct and chimney than other dust density monitors.
- No need to stop the plant for maintenance- integrated zero span calibration: Automated span calibration including the optical system is integrated, and you don`t need to stop the plant for maintenance.
- Insensitive to ambient light (sun light illumination light, etc): The optical sensor is designed to have tolerance for ambient light, and the dust detector can be installed in short duct and chimney.
- Easy one-hole installation: It can be Installed in one place on a duct chimney. Unlike optical penetration method, there is no need to make two holes and to adjust the optical axis.
- Long term maintenance free operation: using the long life LED. the integrated calibration function, and patented proven setf clean system for the optical sensor
- Tolerance for vibration: Simple and robust design; it can be used in large vibration places such as shipboard.
