According to the characteristics of the gas sensor, the sensors selected on various gas alarms are very particular. Because of the inability to make quantitative measurements, semiconductor sensors are mostly used in home alarms and spot-type alcohol detectors, which is more in line with the fact that such alarms only require qualitative measurements and lower price requirements.
Non-pressurized
Solar Water Heater is a cost-effective system for residential hot water
application. this system is designed according to thermosiphon principle and
operating with proportion difference between cold and hot water. The water
heated by Vacuum Tubes is held in the stainless steel storage tank where the
insulation preserves the heat.
The
thermosiphon solar water heater uses the sun to heat the working fluid (mostly
water) in the vacuum tubes. The Solar Collector absorbs solar radiation, and
converts the sunlight to heat and transfer it to the water. The heated water
naturally rises through the solar collector into the water tank where the
cooler water at the bottom of the tank is forced out and descends to the bottom
of the collector (thermosiphon circulation). The circulation will be
interrupted when there is no solar radiation.

Industrial alarms use catalytic combustion sensors and electrochemical sensors because they require quantitative measurements. However, semiconductor sensors were used in the early days, but nowadays, because of the high requirements, almost no manufacturers have used semiconductor sensors. Industrial gas alarms can be classified into point gas detectors and portable gas detectors in terms of usage. Considering the price factor, electrochemical sensors are generally only used in the case of quantitative measurement of toxic gases. For the occasion of the explosion measurement, the catalytic combustion sensor is generally used because of the low requirements.
