The KG-JZ-K5EX explosion-proof speed sensor is an industrial equipment designed specifically for flammable and explosive environments. Its cylindrical design typically balances structural strength and installation convenience. The following are typical technical parameters and key features of this model of sensor:

1、 Basic parameters

1. external structure

• Cylindrical design, with a diameter of approximately 40~60mm and a length of approximately 80~120mm (specific dimensions should refer to the product manual).

• Material: Stainless steel or aluminum alloy shell, surface anti-corrosion treatment (such as sandblasting, anodizing).

• Protection level: IP65~IP67, dustproof and waterproof, suitable for harsh environments.

2. Explosion-proof rating

• Compliant with international standards: Ex d IIC T6 Gb (or Ex ia IIC T4 Ga, depending on the design type).

• Applicable locations: Explosive gas environments such as coal mines, chemicals, petroleum, and natural gas (Zone 1/Zone 2).

2、 Performance parameters

1. measurement range

• Speed: 0.1~10 m/s (customizable higher range).

• Frequency response: 0~1kHz (suitable for low-frequency vibration or rotation speed monitoring).

2. output signal

• Analog quantity: 4~20mA (two-wire system, strong anti-interference ability).

• Digital quantity: RS485/Modbus RTU (supporting multi device networking).

• Pulse output: NPN/PNP type, frequency proportional to speed (e.g. 1kHz corresponds to 10m/s).

3. Accuracy and Resolution

• Linear error: ± 0.5% FS (full scale).

• Resolution: 0.01 m/s (for analog output).

• Repeatability: ± 0.2% FS.

• 
  

3、 Electrical parameters

1. power supply voltage

• DC 24V ± 15% (typical value), supports wide voltage input (such as 12-36V DC).

• Power consumption: ≤ 2W (low-power design, suitable for intrinsic safety circuits).

2. Insulation and voltage resistance

• Insulation resistance: ≥ 100M Ω (tested at 500V DC).

• Voltage resistance strength: 2000V AC/1 minute (without breakdown or flashover).

4、 Environmental adaptability

1. Operating Temperature

• Conventional type: -20 ℃~+60 ℃.

• Wide temperature range: -40 ℃~+85 ℃ (optional).

2. Vibration and Shock

• Vibration resistance: 10g (55~2000Hz, random vibration).

• Impact resistance: 50g (11ms half sine wave).

3. Storage conditions

• Temperature: -40 ℃~+85 ℃.

• Humidity: ≤ 95% RH (no condensation).

• 
  

5、 Installation and Interface

1. Installation method

• Threaded installation: M12~M20 (optional flange or fixture fixation).

• Direction: Axial or radial installation, suitable for different monitoring needs.

2. connection interface

• Cable: Explosion proof flexible tube (standard M20 × 1.5 connector).

• Lead length: 2m (customizable to extend up to 10m).

6、 Certification and Standards

• Explosion proof certification: ATEX, IECEx, CNEx (China Explosion proof Certificate).

• Electromagnetic compatibility (EMC): Complies with the IEC 61000-4 series standards (anti-static, surge, radiation interference).

• Environmental standards: RoHS and REACH compliance.

7、 Application scenarios

• Rotating machinery: speed monitoring of fans, pumps, compressors, and gearboxes.

• Conveyor system: linear speed detection for belt conveyors, elevators, and screw conveyors.

• Safety interlock: linked with PLC/DCS system to achieve overspeed protection or fault warning.

Precautions

1. Avoid strong electromagnetic interference sources (such as frequency converters and welding machines) during installation.

2. Regularly check the coaxiality between the sensor and the object being measured to prevent eccentric wear.

3. Explosion proof sensors are strictly prohibited from being disassembled or repaired in non explosion proof areas.
