Add fixed particulate monitoring to a site control system.
The display and alarms show particulate status at the monitoring point.
Specify the 4–20 mA or RS-485 interface needed by the site.
Choose a suitable location and maintenance access for reliable sampling.
Sampling design and PM size channels must be confirmed for the supplied TCB1000 version.
The TCB1000 dust concentration detector converts airborne dust concentration signals into digital signals, employing a three-wire (4~20) mA current signal/RS485 four-wire bus digital signal output method. It features long transmission distance and excellent anti-interference performance.
The TCB1000 dust concentration detector is a particulate matter analyzer manufactured using self-suction sampling technology based on laser scattering principles. It primarily detects suspended particles in the air (PM1.0, PM2.5, PM10) or large particulate dust, coal dust, airborne dust, and cement dust, with data output presented in concentration-weighted mode.
The instrument employs advanced embedded technology, with the central processing unit (CPU) handling data acquisition. It features high processing speed, strong interference resistance, and superior measurement accuracy. This detector utilizes a full Chinese LCD display, high-precision laser dust concentration detection sensor, high-precision data processor, and high-power safety power supply.
This product is suitable for use in Zone 1 or Zone 2 environments containing explosive mixtures with Class II A to II C and temperature groups T1 to T6. A dust-tight enclosure is required for Zones 21 and 22.
