EnergyTech 501

Ambient Dust Monitor

The perfect monitoring device for coal handling, processing and storage applications.

Ambient emission monitoring analyser


The EnergyTech 501 Ambient Dust Monitor, is an essential part of any application where ambient dust is present such as coal handling, processing and storage. By monitoring the ambient visibility of the handling processes the EnergyTech 501 provides an alarm output for use in containment control.

Fully configurable analogue and alarm outputs are exportable to the plant data acquisition system to provide real-time visibility data. This data is also exported via the RS 485 serial port along with the temperature data. This link delivers MODBUS RTU encoded data to a SCADA system located in the plant control centre and/or a local display module. In addition, the IP65 rated enclosure are coated to resist attack from harsh and aggressive atmospheres. In areas where extremely low temperatures may be experienced, optional transmitter and receiver insulation jackets are available to reduce the effect.
