Nippon E9TRB Triboelectric Probe

The TC sensor detects the passage of particles through the gas, converting this physical phenomenon into an electric signal that is proportional to the level of dust.

Use an internal rotary switch to compare the signal generated by the TC sensor and the pre-set threshold. You can set an alarm at the required value.
If the alarm is caused by a broken filtering element, this can be identified if connected to devices of the ECO series, which are provided with this type of control device.
