Explosion proof air pressure difference a burglar alarm Device, when we hear the name, we will think what kind of machine it is. The so-called differential pressure alarm is a common type of wind pressure sensor in industry, which is widely used. It can be said that it will save a lot of time and energy in industry. Especially dust remover Spraying equipment 、 air conditioner Filter, boiler furnace negative pressure and positive pressure air supply system. Next century Xinggangong will take you to know about the differential pressure alarm.
This equipment consists of two parts:
1) Digital display
2) Air pressure differential sensor
The explosion-proof air pressure differential alarm device adopts the air pressure measurement core imported from the United States, with double row 4-digit digital display, which displays the measured differential pressure value and the control output differential pressure value respectively (user can set freely); belt Power Supply instructions lamp (Power switch button), with audible and visual alarm.
Easy to use. It is suitable for measuring the pressure or differential pressure of various dry and non corrosive gases with high measurement accuracy. After accurate temperature compensation, amplification and external processing, it is converted into 4-20mA standard signal, which is very simple to interface with industrial computer or distribution system. There are M4 screw mounting holes on both sides of the body, and there are threads on the air nozzle. Users can choose screws or M10 * 1.5 nuts for fixation. The default pressure interface is φ 8 pagoda nozzle, where the long nozzle is the high pressure interface and the short nozzle is the low pressure interface. (φ 6 pagoda nozzle or quick connector can also be selected)
In particular, the display function is added to realize the synchronous display of on-site display and upper machine position, which is convenient for on-site personnel to watch and debug. Advanced circuit linearity and temperature compensation technology; Make the transmitter perform better. Compact and solid structure; Small size and light weight; Simple installation; Easy to use. It is suitable for measuring the pressure or differential pressure of various dry and non corrosive gases with high measurement accuracy. After accurate temperature compensation, amplification, conversion into 4-20mA standard signal, interface with industrial computer or distributed system, widely used in the measurement of air duct pressure or flow in petroleum, chemical, metallurgy, power plants, to achieve the control of automatic measurement in production process.
