The smoke-proof stairwell, the escape corridor, and the front room that is used for firefighting are the life passages that are used for evacuation, and the corridors that are used by firefighters to fight the fire. When there is a fire in a building, these life passages are also the corridors that are used to fight the fire. As a result, a higher pressure is preferable because a positive pressure air supply pressure sensor pressurized air supply system with a low residual pressure is not conducive to smoke prevention from the perspective of fire and smoke exhaust. However, because the evacuation door is intended to open in the direction of the evacuation route, the direction of the pressurized air supply of the pressure sensor is exactly the opposite of that of the evacuation equipment. This is because the evacuation door is designed to open in the direction of the evacuation route.

If the pressure is too high, there will be a significant pressure difference between the two sides of the evacuation door that separates the fire stairwell from the fire antechamber and also separates the fire antechamber from the aisle. Because of this, the door won't be able to open in the normal manner, which will have repercussions not only for the operation of the firefighters but also for the evacuation of personnel. save. Before moving forward with anything else, it is necessary to develop a plan for the pressure sensor pressurized air supply that is based on the principles governing safe evacuation.

For the vast majority of the time, the fire-fighting ventilation system takes its pressure readings from a pressure sensor designed specifically for use in firefighting. The pressure sensor directly converts the pressure into directly measurable electricity, amplifies the sensor signal through a signal conditioning circuit, and then collects and processes the data through a high-speed microprocessor (MCU), and outputs And the control signal, and drives the rear circuit to control the electric switch according to the set upper and lower limit pressure values, open or close the bypass valve, and finally realize pressure control. In other words, the pressure sensor does all of this by itself. In other words, the pressure sensor is able to directly convert the pressure into an amount of electricity that is directly measurable.

The micro-fire pressure sensor is most frequently utilized in the following applications: front room elevator front room pressure sensor; stairwell differential pressure pressure sensor; elevator front room air outlet pressure sensor; building positive pressure air supply pressure sensor; positive pressure air supply system pressure sensor; office building and Shopping malls and high-rise buildings; control the pressure sensor of the roof fan; measure and control the positio measure and control the position of the coriolis mass flowmeter micro-fire pressure sensor in the building's air supply system; positive pressure air supply system pressure sensorIt is of the utmost importance that pressure relief be carried out so that, in the event of a fire, the personnel responsible for the evacuation of the building will have no trouble opening the fire door, and at the same time, smoke will not be able to enter the front room or the fire escape corridor stairwell. Both of these outcomes are contingent on pressure relief being carried out.

The performance of the fire pressure sensor is dependable, and it radar type level transmitter has a long life in service thanks to its durable construction. The vast majority of the time, it is utilized in the process of measuring minute pressure differences or the pressure of dry air. It is utilized in a wide variety of wind pressure pipelines as well as natural gas pipelines for the purpose of differential pressure measurement or pressure detection.

The defining characteristics and distinct competitive advantages of ceramic capacitive pressure sensors

The defining characteristics and distinct competitive advantages of ceramic capacitive pressure sensors.

Ceramic is a material that is well-known for its high level of elasticity, resistance to corrosion and wear, resistance to shock and vibration, and a variety of other resistant qualities. Because of the thermal stability properties of ceramics and the thick film resistance of the material, the material's usable temperature range can go as high as 135 degrees Celsius. It can also work at temperatures as low as -40 degrees Celsius. In addition to this, it has a very high precision, as well as a very high stability of measurement. The level of electrical insulation is greater than 2 kilovolts, the output signal strength is high, and the service life is substantial. Additionally, the output signal strength is high.

Ceramic capacitive pressure sensor technology makes use of a structure that is composed of a ceramic base that is fixed in place and a ceramic diaphragm that can move. By utilizing glass paste, the movable diaphragm is given a waterproof seal while also being secured to the base. When making a variable capacitor, the electrode pattern has to be printed on the interior surface that is located between the two halves of the capacitor. In response to changes in the medium pressure that is exerted on the diaphragm, there is a corresponding shift in the capacitance that exists between the two components. After going through the process of being converted and conditioned, the signal is then sent out to be used in other ways after it has been through the processing of the conditioning chip. Ceramic capacitive pressure sensors are a technology that has many advantages, such as a low initial investment, a broad measurement range, favorable temperature characteristics, consistency, and long-term stability. These are just some of the benefits.

Controlling industrial processes and the production of automobiles are two of the most common applications for it found all over the world. The core body of the ceramic capacitive pressure sensor, which is a sealed gauge pressure structure, consists of a ceramic base, a deformable diaphragm, and a hollow sealed cavity. The diaphragm can be deformed in either direction. This structure is made up of three different components: a ceramic base, a deformable diaphragm, and a hollow cavity that has been sealed off. Diaphragm, when the pressure of the core body changes, the deformable membrane bends after bearing the pressure, which results in a change in the spacing between the substrates, which causes a change in the capacitance between the plates, and the capacitance change is converted into a standard output through the conditioning chip (such as 0–5V voltage output, 4–20mA current output, I2C, SPI digital output, etc. ). When the pressure of the core body changes, the diBecause of this, the diaphragm is able to make precise measurements.

Ceramic capacitive pressure sensors have a wide range of applications, including the detection of pressure in water, gas, and liquid media, and they are able to perfectly accommodate the effects of water hammer. Ceramic capacitor flat film structures' inherent ability to avoid clogging makes them ideally suited for use in pressure cookers designed for variable pressure applications. Ceramic capacitive pressure sensors offer a number of additional benefits, including resistance to corrosion and impact, the absence of hysteresis, and strong compatibility with various media. Ceramic capacitors have a wide range of applications across a number of different industries, including but not limited to those that mass flow meter price deal with process control, environmental control, hydraulic and pneumatic equipment, servo valves and transmissions, chemicals and the chemical industry, and medical instruments. Ceramic capacitors are also used extensively in a number of different products.
