HZ-892A-EX Explosion proof Digital Vibration Transmitter

HZ-892A-EX Explosion proof Digital Vibration Transmitter

HZ-892A-EX Explosion proof Digital Vibration TransmitterIt is an integrated device that innovatively integrates high-definition digital display screen, magneto electric vibration sensor, and HART communication module based on classic explosion-proof vibration monitoring technology. By obtaining the national essential safety explosion-proof certification, not only can vibration data be accurately captured in flammable and explosive environments, but also the traditional "blind measurement" limitations can be broken through with real-time visual display, making the vibration status of key equipment such as fans, motors, and pump sets clear at a glance. This provides a dual guarantee of "accurate monitoring+intuitive reading" for equipment management in high-risk industries such as petroleum, chemical, and metallurgy, making it the preferred equipment for predictive maintenance in explosion-proof scenarios.

HZ-892A-EX Explosion proof Digital Display Vibration Transmitter Core Advantages: Digital Display Empowerment, Balancing Safety and Convenience

1. Inherent safety and explosion prevention, building a strong defense line for high-risk scenarios

Explosion proof certification: Explosion proof grade ExiaICT6 Ga (compliant with GB/T 3836.1-2010 and GB/T 3836.4-2010 standards), can be safely applied to Class IIA, IIB, IIC T1-T6 flammable gas environments, fully covering Zone 1 and Zone 2 of danger, and eliminating the risk of monitoring equipment becoming an ignition source.

Durable Protection Design: Equipped with a 304 stainless steel casing and an IP65 protection rating, it effectively resists corrosion from chemical media, accumulation of industrial dust, and invasion of humid water vapor, and is suitable for long-term operation in harsh industrial environments.

2. High definition digital display screen, real-time visualization of vibration data

Intuitive reading experience: Equipped with a 1.5-inch segmented LCD digital display screen, it clearly displays real-time values of vibration acceleration (g), velocity (mm/s), and displacement (μ m), supports automatic unit switching, and can quickly grasp equipment status on site without connecting terminals.

Humanized design: The screen comes with backlight function, which can read clearly in strong or dim environments; Low power display technology that does not affect the overall battery life and explosion-proof performance of the device, suitable for 24-hour continuous monitoring scenarios.

3. Dual mode communication with HART protocol for more efficient intelligent operation and maintenance

Bidirectional data transmission: Based on the 4-20mA standard analog signal, the HART digital protocol (using FSK frequency shift keying technology) is superimposed to ensure stable transmission of vibration data and support remote configuration (such as range setting, parameter calibration) and fault diagnosis, reducing on-site operation frequency.

Strong system compatibility: It can seamlessly integrate with industrial automation systems such as DCS and PLC, and support linkage with HART controllers and intelligent gateways to achieve centralized management and historical trend analysis of vibration data, providing data support for equipment fault warning.

4. Multi parameter precision monitoring, covering all scene requirements

Full dimensional data collection:

Acceleration: 1-5g peak range, accurately capturing the impact vibration of high-speed rotating equipment (such as compressors);

Speed: 0-100mm/s effective value (conventional selection 0-20mm/s), effectively monitoring common faults such as bearing wear and rotor imbalance;

Displacement: peak to peak value of 0-1900 μ m (commonly 0-200 μ m), real-time perception of abnormal radial clearance of the shaft system, to prevent the risk of equipment jamming.

Broadband response capability: The standard frequency response is 10-1000Hz, and it can be extended to 5-1000Hz in special scenarios. Both high and low frequency vibration signals can be accurately captured, adapting to the monitoring needs of different types of industrial equipment.

5. Strong environmental adaptability and stable operation under working conditions

Wide temperature tolerance: The working temperature range is -40 ℃~80 ℃. It can operate stably in cold outdoor environments in the north, high-temperature workshops in the south, chemical reaction vessels, and other temperature scenarios without data drift or shutdown risks.

Anti interference and long-distance transmission: Adopting a two-wire transmission architecture, the output impedance is ≤ 500 Ω, effectively shielding industrial site electromagnetic and radio frequency interference; The signal transmission distance exceeds 1000 meters, meeting the cross regional monitoring needs of large factories.
