- The DustAlarm Broken Bag Detector provides reliable and economical detection of leaks and filter failures in many powder and bulk solids industries. The DustAlarm is successfully utilized in a wide variety of applications where detection of dust levels is critical either to safety, maintenance, equipment operation, plant efficiency and/or the environment. The DustAlarm measures the triboelectric effect to determine when particle emissions exceed acceptable levels.
The DustAlarm Broken Bag Detector incorporates visual indications and a relay output to maximize its user-friendliness and automation capabilities. A reference point is set by the sensitivity control adjustment, aided by the tri-color LED. The alarm point is set by an alarm level control adjustment. The relay output can be used to activate an alarm device or can be integrated into a control system to enhance the overall operation of the dust collector.
Triboelectric measurement, which has been used for broken bag detection for many years. Also known as particle impingement or frictional electrification, the triboelectric effect pertains to the resulting charge transfer when one material rubs or impacts another.The result of dust particle collision with a stainless steel probe is the generation of electrical signals, which are continuously monitored and analyzed by the electronics. When the signal exceeds a preset level, a time delay is initiated. If the signal remains above the preset level for the duration of the delay, alarm relay outputs are energized.
- Features:
- Adjustable Sensitivity, Alarm Level and Time Delay for Operation with a Wide Variety of Powders and Bulk Solids
- Integral Assembly of Sensor and Electronics in Rugged NEMA 4 Housing
- Remote Electronics/Probe Option Available
- 316 Stainless Steel Probe with Specially Designed Insulator
- Multi-Colored LED Indicator Makes Setup Quick and Easy
- Quick-Disconnect Mounting Provides for Ease of Installation and Maintenance

I took a gamble on this sweater, amazon clothing seems to sometimes be way different quality than what’s pictured but I was very happy when I received this sweater!

his sweater is a bulky, fairly heavy winter sweater that will be awesome for the office or casual wear. The fabric is very silky soft. It’s nice and snuggly! I can’t wait for it to get cool enough to wear it!
