DUSTGUARD PARTICULATE MONITOR PM-250
Process Trend Monitor and Multi-Purpose Dust Alarm with display A real time continuous indicative dust monitor with logging & alarm capability. Low cost solution to monitoring requirements.
- Quick & easy single point installation with no moving parts.
- Low capital & maintenance costs.
- High Sensitivity.
- Can be calibrated to show emission levels in mg / m3.
- Adjustable range from 1-1,000 mg/m3.
- Minimum detection limit less than 1 mg/m3.
The Stack Guard series operate on the principle of Tribo – Electric charge transfer. The electrical charge carried by dust particles is captured by a highly sensitive Tribo – Electric probe, amplified and then transmitted to the control unit. As the current generated by the charge is proportional to the concentration of particles present, an indicative signal of dust presence results.
Stack Guard is most suitable for use in Low Humidity gas streams with reasonably constant flows. The Control unit is mains powered, & incorporates alphanumeric display with Adjustable alarm levels.
1. Dust levels at which the red LED light, alarm is triggered
2. The emissions level at which the audible and visual alarm is triggered
