Overview

The turbidity dust monitor can be customized with improved AC coupling technology, which 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. The main body of the sensor is designed with airtight connectors to prevent the leakage of the measured gas and the outward impact of the measuring electrode due to pressure, ensuring the safety of the transmitter and personnel.

Product Details

Turbidity dust monitoring instrument can be customizedTechnical 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 compatibility Can 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

Turbidity dust monitoring instrument can be customizedPrecautions for use

Installation location: Priority should be given to vertical pipelines or areas with stable airflow, avoiding turbulent areas such as valves and elbows; When installing horizontal pipelines, it is necessary to avoid sedimentation at the bottom.

Environmental interference: Keep away from high humidity, strong vibration, or corrosive gas environments, and install protective covers or explosion-proof enclosures if necessary.

Regular calibration: Calibrate the equipment according to the manufacturer's recommended cycle, use standard reference materials to verify accuracy, and ensure that the isolator functions properly.

Cleaning and maintenance: Although it has self-cleaning function, it is still necessary to regularly inspect the sensor surface to prevent stubborn dust accumulation from affecting sensitivity.

Compliance: Ensure that the equipment complies with local environmental regulations and occupational health standards, and that installation and operation procedures comply with safety regulations.

Data utilization: Combining historical trends with real-time data, optimize production processes and emergency plans to avoid misjudgment of single data.
