The portable turbidity dust monitor adopts high temperature resistant and corrosion-resistant materials, suitable for harsh industrial environments. Some models have explosion-proof certification, meeting the requirements of flammable and explosive scenarios. Real time monitoring of smoke and dust emissions from coal-fired boilers, cement plants, and waste incineration plants to assist enterprises in meeting emission standards.
Portable turbidity dust monitoring instrumentApplication field
Industrial production safety: Monitor the concentration of combustible dust in coal mines, metal processing, grain storage and other places to prevent explosion accidents.
Environmental supervision: Real time monitoring of smoke and dust emissions from coal-fired boilers, cement plants, and waste incineration plants to assist enterprises in meeting emission standards.
Occupational health management: Monitor inhalable particulate matter in tunnel construction, pharmaceutical workshops, electronic cleanrooms, and other scenarios to protect workers' respiratory health.
Quality control: Control dust concentration in the production of milk powder and starch to ensure product purity; Monitor the dust overflow in the packaging section of the feed factory and optimize the working environment.
Energy efficiency optimization: By monitoring the dust concentration at the mill outlet, adjusting the operating frequency of the bag filter, and reducing power consumption.
Portable turbidity dust monitoring instrumentTechnical Specifications:
1. Output mode: 4-20mA (or RS485 communication, Modbus RTU protocol, switch quantity, etc.),
Advantages of HART Protocol - Export Equipment Customization:
Simultaneously including analog and digital communication, compatible with traditional analog instrument solutions, supporting multivariable field devices, flexible data access through two hosts, de facto open standards, backward compatibilityCan support both analog and digital protocols, unlike other fieldbuses that are essentially digital, point-to-point or multi-point operations, with a response time of approximately 0.5 seconds. The HART protocol is a unique backward compatible communication facility that ensures that existing investments in factory cables and power requirements remain secure in the future. It is a communication facility that supports both analog and digital communication (hybrid) simultaneously. By retaining the traditional 4-20 mA signal, it extends the bidirectional digital communication capability between the system and multivariable intelligent field instruments. Any process application can be serviced and processed by the HART protocol.
2. Wire system: 2-wire system, 4-wire system
3. Display: Yes or No Display
4. Pipeline gas temperature: Conventional 0 ℃~250 ℃, High temperature type 260 ℃~800 ℃ can be customized
5. Is there an alarm: Yes, No
6. Do you need an isolator (function?): Yes (built-in is an advantage, others are external), No need
6. Range: 0-10mg/50mg/100mg/200mg/1000mg/30g/100g/m ³ (special ranges can be customized)
7. Principle: Electrostatic Induction Principle
