Product overview
3.1
Product description
This device is designed for continuous measuring of total suspended particles (TSP) in ambient air. It is
an ideal solution for industrial applications where a disruption in normal operations can result in an
increase in dust particle concentration in ambient air, which can cause further equipment malfunction or
even pose a risk to worker health.
The operating principle is based on inductive electrification technology, where particles interacting with
an isolated probe induce a signal that is transmitted to the monitoring system. The normal dust level is
determined during commissioning, and the signal generated by the sensor is then scaled in proportion to
this baseline level when the dust level fluctuates.
The device is intended for use in non-condensing environments. The sensor does not
distinguish liquid droplets from dust particles. If the measured airflow contains liquid
droplets, the measurement results are inaccurate.
The device has a local user interface with six keys and a 7-segment display with four digits for indicating
measurement results and device status.

3.1.2
Commissioning
Commissioning is easy with Auto Setup feature, which determines the baseline dust level and sets up
two alarm thresholds that are proportional to the baseline. An alarm is triggered when the dust
concentration exceeds a configured threshold.

Installation
The device is installed by simply securing it to the installation location with four screws through the
built-in mounting feet. Mounting feet are suitable for standard wall, ceiling and tabletop installations.
