Semiconductor NH3 gas sensor Introduction
Semiconductor NH3 gas sensor is a gas sensor with high sensitivity to ammonia gas. The late circuit of ammonia gas sensor is simple and the anti-environment ability is strong. The response time of semiconductor NH3 gas sensor to low concentration ammonia gas is very short. It has the advantages of long life, low cost, high sensitivity, simple driving circuit, fast response and recovery time, etc. Ammonia semiconductor sensor is widely used in refrigerator gas detection, refrigeration warehouse ammonia leakage detection, agriculture and aquaculture risk control.
Semiconductor NH3 gas sensor Features
1, the machine is small in size, light in weight, easy to install, can be mounted in portable, fixed, pipe type and other appearance sensors used.
2, stainless steel protective net, high protection, easy to clean effective protection from particulate matter and impurities, easy to maintain and use.
3, high-performance chip, breakthrough manufacturing process, product performance significantly improved.
4, long service life, low cost, simple driving circuit.
5, high resolution, high sensitivity, fast response speed, strong anti-interference force.
Semiconductor NH3 gas sensor Parameters
Product model: JQ-137
Product type: semiconductor gas sensor
Standard package: Plastic seal
Detection gas: ammonia gas
Detection concentration: 5~500PPM ammonia gas
Loop voltage: ≤24V DC
Load resistance: adjustable
Temperature/humidity: 20°C, 2°C; 55% soil 5%RH
Attention:
1. Avoid exposure to volatile silica vapors.
2, avoid sensor exposure to high concentration of corrosive gas.
3, avoid alkali, alkali metal salt, halogen pollution.
4, avoid the sensor contact with water or immersed in water, easy to cause the sensor sensitivity characteristics decline.
5, avoid applying too high voltage, if the voltage applied to the sensor heating is higher than the specified value, even if the sensor has not received physical damage or damage, it will cause damage to the lead/or heater, and cause the sensor sensitive characteristics to decline.
FAQs：
Where should the nh3 sensor location?
The ammonia sensor should be installed in a place where the gas is easy to leak, and it is determined according to the specific gravity of the detected gas relative to the air.
When the specific gravity of the detected gas is greater than the specific gravity of air, the detector should be installed (30-60) cm away from the ground, with the ammonia alarm position facing downwards.
What are the types of ammonia sensors?
Our company provides three types of NH3 gas sensors according to the different places where customers use them: wall-mounted ammonia sensors, portable ammonia detectors, and fixed ammonia alarms.
