Electronic Air Pressure Sensor Features There are mechanical and electrical types on the market for air pressure switches and sensors. Generally, we call the electrical type an air pressure sensor and the mechanical type an air pressure switch. The difference is the trigger mechanism; the magnetic core drives the electrical air pressure sensor, but the mechanical air pressure switch is driven by the mechanical structure ( like the spring, leaf, etc.). So, the working principle decides the different performance for them. The electrical type will have a longer operating life as the failure rate is much lower than the mechanical type. Meanwhile, the air pressure sensor can also detect many air pressure points simultaneously, but the mechanical type can not. However, the mechanical type will have a lower price and can also be used in many kinds of applications if you don’t have a high requirement. Besides, the mechanical type also has not had many technical requirements for the customer when they use the switch in their product. All in all, you can choose the sensor or switch type as you need; if you don’t know how to choose the model, welcome to contact us for more details.

S11 Steam Condensate Separator Features You can see the Steam Condensate Separator in the middle of the pressure switch and hoses, when the tail gas comes out and meet the cold air, the tail gas will become water drop inside the hoses to plug up the tube or even drop out the pressure switch and fan, which will lead to system failure and alarm. With this separator, it can avoid this situation happen. Generally, this can be used in the wall-hanging furnace boiler because the wall-hanging boiler meets this situation often but the water heater is not often. Because the furnace environment will lead to a drop of water, which will come back to the pressure switch or draught fan. So, this situation will cause the malfunction of the furnace. Meanwhile, this steam condensate separator can drain away water automatically so you don’t need to operate it by hand. The inside of the separator has a float ball, when the water is filled with the water, the ball will be raised up, and then the condensate water will be drained. About the connection with the pressure switch. For more parts of the air pressure switch and flow sensor, please click the link to check. Besides, we also provide the air pressure switch, water pressure switch, flow sensor, etc. which is also can be used in the wall-hanging boiler. We can provide the ONE-STOP solution for you.

Coffee machine water pressure switch function The water pressure switch function in a coffee machine is usually used to control the volume of water and the pressure at which it flows, to ensure the quality and taste of the coffee. The water pressure switch works by detecting the flow and pressure of the water in the coffee machine, to regulate the concentration and taste of the coffee. This switch can adjust the flow and pressure of water to adapt to different types of coffee beans and to meet different taste demands, while also ensuring the efficiency and stability of coffee production. Coffee machine water pressure switching principle The principle behind the water pressure switch in a coffee machine is to use water pressure as an indicator of the flow rate and volume of water the machine is producing. It works by using a diaphragm or spring-loaded piston inside the switch that senses the water pressure inside the machine. When the water pressure reaches a certain predetermined level, the switch triggers a signal that turns off or regulates the flow of water to the coffee maker. This helps to prevent overpressure and ensure that the coffee machine is producing consistent and high-quality coffee with the correct water pressure and flow rate.

Negative Air Pressure Sensor C7 negative air pressure sensor can simultaneously measure many water board levels and any position in a specific pressure range. It can contact a digital monitor to show the pressure value, and the signal output is done through the L/C oscillation principle to convert it into a square wave signal. The pressure sensor is the perfect updated vision of the pressure switch, which has a longer service life and more water level detection. So, the negative air pressure sensor will be used for the gas water heater and boiler and the large ventilation heating air control system. Generally, the detect pressure range is from 20 Pa to 80 Pa, which is the low-pressure type but as a pressure sensor company; we accept the OEM service. Welcome to discuss the customized project with us. Meanwhile, whether the pressure sensor or the pressure switch also has a negative and positive type, please send an inquiry to us to know more.

C5 Air Pressure Switch Boiler Sensor Function The gas water heater’s air pressure switch (which is actually the air pressure sensor), usually located in the upper right corner of the water heater, is a disc-shaped object about the size of a teacup lid, connected by three wires, and a hollow plastic tube. The air pressure sensor works roughly like this The water-gas linkage device of the gas water heater is started by the water flow after the hot water bridle is opened. The physical displacement drives the micro switch, opens the solenoid valve to supply gas, and triggers the ignition circuit. At the same time, the micro switch also starts the strong exhaust fan, which starts the forced exhaust system, the strong exhaust fan has a bypass, through a small plastic pipe, to provide air pressure to the wind pressure sensor, the wind pressure sensor built-in film, one side is subject to wind pressure (air pressure), the sensor signal is continuously and stably provided to the ignition control loop, once the sensor signal is interrupted, The machine logic automatically cuts off the ignition circuit and closes the air valve. Eventually, it will cause the water heater to passively stop working. Air Pressure Switch Boiler Sensor 5mA 5VDC (1116) Please the link to learn about other sensor-related products Main parameters of the Air Pressure Switch Boiler (1) Linearity: Air Pressure Switch Boiler refers to the degree to which the actual relation curve between sensor output and input deviates from the fitting line. Defined as the ratio of the maximum deviation between the actual characteristic curve and the fitted line in the full-scale range to the output value of the full scale. (2) Sensitivity: Sensitivity is an important indicator of the static characteristics of the sensor. It is defined as the ratio of an increment in an output quantity to the corresponding increment in an input quantity that causes the increment. The sensitivity is indicated by S. (3) Hysteresis: When the input quantity of the sensor changes from small to large (positive stroke) and the input quantity changes from large to small (reverse stroke), the input-output characteristic curve does not coincide, which becomes hysteresis. For the same size of the input signal, the positive and negative stroke of the sensor output signal size is not equal, this difference is called the hysteresis value. (4) Repeatability: Repeatability refers to the degree of inconsistency of the characteristic curve obtained when the input of the sensor changes continuously in the full range in the same direction. (5) Drift: the drift of the sensor refers to the output of the sensor changes with time when the input is unchanged, and the second phenomenon is called drift. There are two reasons for the drift: one is the structural parameters of the sensor itself; Second, the surrounding environment (such as temperature, humidity, etc.).
