GT500A Explosion proof Carbon Monoxide Gas Detector Industrial High Precision CO Concentration Monitor

Description :

  The GT500A carbon monoxide sensor is a gas detection instrument designed specifically for industrial hazardous environments. It is mainly used for real-time monitoring of the concentration of carbon monoxide (CO) in the air to prevent poisoning or explosion accidents caused by gas leaks. This device adopts advanced electrochemical sensing technology, which has high sensitivity and fast response characteristics, and can accurately capture small concentration changes. Suitable for places with carbon monoxide leakage risks such as petrochemicals, coal mines, metallurgical casting, underground pipe galleries, etc., providing reliable data support for safe production and solving the pain points of slow response and large errors of traditional detection equipment.

  The housing of GT500A carbon monoxide sensor is usually made of high-strength aluminum alloy or stainless steel material, with anti-corrosion treatment on the surface, and has a protection level of IP65 or above, suitable for harsh working conditions such as high temperature, high humidity, and large dust. Its core parameters include a measurement range of 0-1000ppm (customizable according to requirements), a resolution of 1ppm, and a basic error of ≤± 3% FS. The equipment complies with the GB3836 series explosion-proof standards and has obtained an explosion-proof certificate to ensure safe operation in flammable and explosive environments. The signal output supports 4-20mA analog, RS485 Modbus digital, and relay switch values, making it easy to connect to PLC, DCS systems, or alarm controllers for remote monitoring and linkage control.

  When selecting the GT500A carbon monoxide sensor, it is necessary to clarify that the gas type on site is only CO, and if there are interfering gases such as hydrogen sulfide, anti-interference or composite detectors should be selected. This model is suitable for fixed installation scenarios, and handheld devices should be selected for portable testing. Compared with ordinary civilian sensors, GT500A has explosion-proof certification and stronger environmental adaptability, and cannot be replaced or used in ordinary areas without explosion-proof treatment. When purchasing, it is necessary to confirm the power supply voltage (usually 24V DC) and transmission distance. For long-distance transmission, it is recommended to use RS485 communication method to reduce signal attenuation and ensure data stability.

  When installing the GT500A carbon monoxide sensor, it should be selected in a location where the gas is easy to accumulate and has good ventilation, with a horizontal distance of 1-2 meters from the release source. The height should be adjusted according to the gas density, and CO density is slightly lighter than air. It is recommended to install it 0.5-1 meter from the ceiling. Routine maintenance requires regular calibration using standard gases, and it is recommended to calibrate every 3-6 months to ensure measurement accuracy. The lifespan of sensor probes is usually 2-3 years. If there is a large reading drift or a longer response time, the probe should be replaced in a timely manner. Avoid exposing the sensor to silicone substances or high concentration solvents to prevent sensor poisoning and failure. Regularly check for loose wiring terminals to ensure reliable circuit connections.
