1、 TVOC gas concentration alarm product introduction

The BYG500-TVOC fixed organic volatile gas transmitter continuously detects TVOC gas in the atmosphere online and provides sound and light alarms. It not only controls gas concentration in special occasions, but also has a warning effect on gas leaks in dangerous sites, timely protecting the safety of life and property on various sites. Instruments are widely used in industries such as petroleum, chemical, metallurgy, fire protection, coal mining, electricity, ships, environmental protection, telecommunications, and medical care. The BYG500-TVOC organic volatile gas detector adopts imported electrochemical principle sensors combined with high-speed and high-precision processing circuits, which have the advantages of stable signals, high accuracy, and good repeatability. It also adopts explosion-proof design and is suitable for various hazardous occasions. The instrument outputs various standard signals and is compatible with various alarm systems, PLC, DCS and other control systems.

3、 Technical parameters of TVOC gas concentration alarm

4、 Installation method of TVOC gas concentration alarm

Installation location:

According to the specific gravity and wind direction of the gas, the transmitter should be installed within one meter of the possible gas leakage location, so that the actual response speed of the transmitter is relatively fast. Otherwise, there may be a phenomenon where the TVOC gas or toxic and harmful gas concentration at the transmitter installation location does not exceed the standard, but the local gas at the leakage point has already exceeded the standard, and the transmitter and host cannot alarm.

The installation height of the transmitter above the ground should be greater than 30 centimeters to prevent water splashing in. In general, for detecting harmful gases with a specific gravity lower than that of air, the probe should be installed above the house or equipment; For harmful gases with a specific gravity greater than that of air, the probe should be installed close to the ground.

The installation probe of the transmitter should face downwards. If installed outdoors, a rain shield should be added above the transmitter.

be careful:

1. The detection range of each probe in the open area is 100 square meters, while also considering factors such as gas diffusion, wind direction, temperature, humidity, and area enclosure.

2. During installation, protective measures such as dust, water, and high temperature prevention should also be considered.

5、 Precautions for TVOC gas concentration alarm

1. It is strictly prohibited to perform live lid opening operations on site

2. It is strictly prohibited to replace sensors with electricity

3. Installation, debugging, setup, and other operations must be carried out by professionals

4. The calibration check of the transmitter should be conducted regularly

5. Sensors that have exceeded their expiration date or have malfunctions should be replaced promptly

6. Avoid using gas shock sensors that exceed the measurement range
