Dust Sensor Controller – Sentinel 1
eSentry 4 Controller & Process Interface
The Atlas dust sensor has two (2) dust channels, instanteous and 2 rolling average channels. The sensor handles all of the rolling average calculations as well as all alarming functions for all dust channels, including alarm delays. Each rolling average periods and alarm setting for each channel is independently configurable. All you have to do is read the data registers.
Team the Atlas with one of our interface controllers and you have one of the most powerful compliance and diagnbostic tools on the market. The Interface Controller can store and back-up data to a UCB drive so you can easily grab the history to help identify process changes or use the data to EPA MACT reporting.
