Bag leak detector

1、 Product Introduction

BDM series integratedBag leak detectorThere are three types of products: BDM-X integrated dust concentration transmitter, BDM-Z integrated dust concentration transmitter, and BDM-H integrated dust concentration transmitter, which adopt the charge induction measurement principle of * and are developed and produced by our company. The new circuit design, application of new devices, sealing technology for measuring electrodes, high-tech spray insulation, and stable amplification of very weak charge signals ensure continuous online measurement of dust concentration. the productThe product has a high level of technical expertise in the industryObtained certificates of appearance design, utility model, and explosion-proof qualification.

Bag leak detectorWidely used for online measurement of dust concentration in gas-solid two-phase flow in industries such as steel, power generation, petroleum, chemical, cement, mining, etc. Typical applications: Bag dust removal for ironmaking blast furnace gas, TRT power generation, dry, wet, electrostatic dust removal, online continuous monitoring of smoke and dust emission concentration from coal powder boilers, replacing the old method of manual sampling and analysis in the past. It timely detects the concentration of emitted dust, avoids the loss of usable dust, protects production equipment for gas reuse, reduces consumption, and is highly welcomed by users!

2、 Working principle

During the transportation of gas-solid two-phase fluids containing dust particles, the collision and friction between dust particles and dust particles, as well as between dust particles and the inner wall of pipelines, will cause the dust particles to carry charges and form an electrostatic field. When charged dust particles pass through the measuring electrode, positive and negative charges are induced by the measuring electrode, and the charges form a current signal during the transfer motion; The magnitude of this AC signal is directly proportional to the mass content of dust. By further amplifying and processing this electrical signal, the dust concentration (mg/m) can be accurately measured³）.

3、 Product Features

1.Using the principle of charge induction to measure dust concentration, the measurement accuracy is high.

2.Integrated structure, long distance for current signal transmission, strong resistance.

3.The measuring electrode is coated with imported protective material, which improves its ability to withstand high temperatures, corrosion, and adhesion, reduces cleaning and maintenance, and extends its service life. Improved product quality.

4. 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,Guaranteed the transmitterNormal operationandreduceworking personneldanger.

5.haveAutomatic zero adjustment function, convenient for checking zero point.

6.DC24VNon polarized power supply, convenient wiring to avoid wiring errors and damage to the transmitter.

7.BDM-HThe model adopts intelligent circuit design, with three alarm outputs, and the alarm value can be set arbitrarily.
