Dust detector without display

1、 Product Overview

GLT-F seriesDust detector without displayMeasure the electrostatic induction of dust particles passing through a fixed probe. Dust particles and probes induce static charges, which are amplified by the probe and transmitted to the monitoring and control system. The size of static charge is proportional to the flow rate of dust particles. The high-tech electronic circuit of this system converts this part of the charge into a control signal output, activates the dust over limit emission alarm, and is used to continuously record the total amount or concentration of dust particles.

The GLT-F series devices provide the current world's AC coupling technology. This is a modern, precise and stable monitoring technology, particularly suitable for continuous emission recording and data accumulation. The working principle of this monitoring system is to use the charge induction generated by the flow of dust particles around the probe to confirm the online emission amount (mg/sec) or emission concentration (mg/m3) of dust particles. Under relatively stable combustion conditions (i.e. at the same emission point, there is no significant change in flow rate, temperature, pressure, humidity, and particulate properties of smoke particles, with a variation of less than ± 90%), this system can also be used for online monitoring of emission concentration (unit=mg/M3) after direct calibration.

2、 Scope of use

GLT-F seriesDust detector without displayWidely used in various industrial applications, including steelmaking, power generation, petroleum, chemical, pharmaceutical, building materials processing, coal mining and mining, cement manufacturing and packaging industries. Typical applications include detecting damaged filter bags in bag filters, recovering powdered materials, monitoring the total amount of product transportation, or monitoring the concentration of smoke and dust emissions from boilers of various sizes and fuels.

3、 Product Features

1. Adopting advanced practical technology - improved AC coupling technology, it has high sensitivity and good linearity for dust detection. Dust contamination of the probe does not affect the measurement sensitivity and is maintenance free and cleaning free.

2. Standard two-wire 4-20mA current output (other output methods can be customized), strong anti-interference ability, easy long-distance signal transmission, no special requirements for signal transmission wires, linear relationship between output current and dust concentration, convenient for subsequent PLC data processing.

3. The integrated transmitter output 4-20mA current in the junction box is electrically isolated from the dust sensing probe to achieve safe signal transmission.

4. 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.

5. The main body of the sensor is designed with airtight connectors to prevent the leakage of the measured gas and the outward impact and extrusion of the measuring electrode due to pressure, ensuring the safety of the transmitter and personnel.
