Detailed Product Description
Fixed Gas Detector Description
GTQ-BS03 fixed gas detector is designed for industrial and commercial use. By adopting high-performance gas sensor and MCU technology, combined with sophisticated SMT manufacturing process, this detector has good repeatability, high accuracy and long lifespan.This detector is widely used in gas detection in petroleum and petrochemical industries, refineries, chemical plants, metallurgical industries, power industries, and other places that may produce harmful gases to the human body.
Fixed Gas Detector Key features
- High measurement accuracy, stable performance and long service life
- 4-20mA analog output or FBUS digital output
- 3 relay outputs (2 free contact, 1 active relay)
- High-performance LCD screen display
- Non-contact operation by infrared remote control
- Smart sensor module, free of calibration, easy to maintain
Electrochemical
Sensor Principle 1. Principle: Using the active
chemical properties of the gas to be measured, it has reducing or oxidizing
properties. In the process of participating in the chemical reaction, electrons
are released or absorbed. A large number of electrons form a current. The
current size is proportional to the gas concentration. The concentration of the
gas to be measured can be measured by measuring the current size. 2. Advantages: The performance is
relatively stable. Most toxic and harmful gases can be measured by
electrochemical sensors, and the measurement linearity is very good. 3. Disadvantages: Electrochemical
sensors are consumables with a relatively short service life. The service life
is 1-2 years in general environment, and needs to be replaced every 3-6 months
in harsh environment. The maintenance cost is relatively high. 4. Use: It is mainly used
for the detection of toxic and harmful gases.
