Overview

The dust concentration monitor at the inlet of the fan is an integrated structure, and the measuring electrode is made of imported protective materials, which improves the ability to withstand high temperatures, corrosion, and adhesion, reduces cleaning and maintenance, extends the service life, and improves product quality.

Product Details

Fan inlet dust concentration monitorHigh sensitivity and good linearity for dust detection. Dust contamination of the probe does not affect the measurement sensitivity and requires no maintenance or cleaning. Adopting a standard two-wire 4-20mA current output (other output methods can be customized), it has strong anti-interference ability and is easy to transmit signals over long distances. There are no special requirements for signal transmission wires, and the output current is linearly related to dust concentration, making it convenient for subsequent PLC data processing. The integrated transmitter output 4-20mA current in the junction box is electrically isolated from the dust sensing probe to achieve safe signal transmission. The product has an integrated structure, and the measuring electrodes are made of imported protective materials, which improves the ability to withstand high temperatures, corrosion, and adhesion, reduces cleaning and maintenance, extends the service life, and improves product quality.
