ET 301 – CEMS

The ET 301 is a dust monitor using well proven technology providing accurate and rapid results Being adaptable it can be used on duct sizes from 250mm to 5m making the ET 301 a suitable sensor for a wide range of applications where a dust measurement is required
ET 301 continuous dust monitor uses the well proven sensor technology to directly measure mass particulate concentration by sensing the frictional charge created when particles collide with a conductor

The advanced electronics of the ET 301 detect this signal and present it to the operator via RS485

or 4 20mA directly out from the sensor head The ET 301 also features a built in display for

viewing live sensor data as well as for configuration and calibration

The measurement levels can be corrected to mgm3 via an integrated calibration function

The technique is extremely sensitive capable of detecting dust concentrations of less than 1mgm3 in small ducts

The ET 301 requires no critical alignment and has no optical surfaces to keep clean The sensor is easy to install requiring only a simple probe and is ideal for small duct sizes

Minimal maintenance is required infrequent probe cleaning and low installation costs make this technology extremely attractive for Dust collector monitoring
