Fixed dust detector dust sensor
The YF-8801-PM series dust concentration detector measures the electrostatic induction of dust particles passing through a fixed probe. Dust particles
Product details
The YF-8801-PM series dust concentration detector is widely 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.
ØProduct Introduction
The YF-8801-PM series dust concentration detector has four major features:
1. Adopting the most advanced practical technology - patented 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-line system4-20mACurrent output, 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 usePLCData processing.
3. The installation and use are completely consistent with the two-wire pressure transmitter, and on-site engineering and technical personnel can use it correctly without any special training. The installation is convenient and the operation is reliable.
4. The junction box is equipped with an integrated transmitter output4-20mAElectrical isolation is achieved between the current and dust sensing probes to ensure safe signal transmission.
