Application of GLTV7S series capacitive level sensor in UAV level measurement Current Status of Drone Industry With the popularization of drones, civil applications such as engineering detection and agriculture are becoming more and more widely used. Because the fuel is exhausted and it is too late to return, the phenomenon of bombing often occurs. In agricultural application, spraying fertilizer can only judge the level of liquid level by simple calculation of time, which may lead to the phenomenon of missing hitting and cause disputes. Due to the weight problem, the traditional liquid level measuring instrument has always been a troublesome problem in the application of the drone industry.,without the detection instrument, the measurement and warning effect cannot be achieved, but the traditional detection instrument is too heavy, which will cause the reduction of the UAV's endurance range. Therefore, it is urgent to develop a light weight measuring instrument for the application of UAV oil level and liquid level detection. Solution In order to realize the real-time monitoring of UAV oil level, agricultural UAV oil level and liquid level monitoring, our GLTV7S series capacitive oil level sensor can effectively monitor the oil level and liquid level, and the oil level monitoring can provide real-time feedback on the remaining oil volume, so that the pilot can operate at ease.Low fuel level alarm, when the fuel level is lower than the warning value, you can choose to return or hover to prevent the phenomenon of bombing and make the intelligence go further.It can also display real-time liquid level and makes UAV plan a reasonable return point and dressing route, and make an intelligent return. The low liquid level alarm can effectively prevent leakage and make farmers more at ease. Quality assurance, quantity preservation, and dispute prevention allow the pilot to give farmers a satisfactory answer. Product Introduction Measuring Principle:GLTV7S series UAV oil level liquid level monitoring instrument is to use the liquid medium between the positive and negative probes to form a capacitance that changes linearly with the liquid level, and convert the change in capacitance (that is, the change in liquid level) to into a standard electrical signal output. The core component of the product adopts a highly integrated special capacitance measurement chip, which has the advantages of high precision, high stability and continuous measurement after accurate temperature compensation and linear correction. Production process: GLTV7S is using stainless steel finishing process, the weight of 100mm range can be achieved within 100g, which can not only effectively monitor the oil level, but also will not cause a burden on the endurance of the UAV, greatly improving the performance of the UAV.

Air compressors can be used in aerodynamics, gas transportation, gas refrigeration and separation, etc., and are widely used in the automation industry, electronic circuits, water treatment and pharmaceutical industries. They are also used in various factories, road construction, mining and construction industries. The air compressor is the main body of the air source equipment, which converts the mechanical energy of the prime mover into gas pressure energy. It is a device for generating air pressure of compressed air. The safe operation of the air compressor is inseparable from the support of various sensors inside. The pressure sensor is the most important, and it is an indispensable sensor to ensure the normal operation of the air compressor. Taking the screw air compressor as an example, the normal operation of the air compressor is divided into several processes: suction, sealing, transportation, compression, and exhaust. During the transportation process, the oil vapor is compressed and the oil and gas mixed gas with higher pressure is discharged. In the air compressor control system, the pressure sensor installed on the air outlet pipe at the rear end of the air compressor is used to control the pressure of the air compressor. When the air compressor starts running, the pressure value will gradually increase. When the compressed air pressure does not reach the upper pressure limit, the motor keeps running under load. When the pressure reaches the upper limit, the pressure sensor will send an unloading signal, the solenoid valve stops working, and the air intake Turn off, the motor runs at no load, so as to protect the air compressor from normal operation, and avoid damage to the equipment caused by the air compressor operating under load under high pressure. In the air compressor safety management system, the pressure sensor can also help complete the side airbag control. There are two plans for the operation of the airbag on the side of the air compressor: acceleration sensor and pressure sensor. Compared with the acceleration sensor, the pressure sensor is nearly three times faster than the acceleration sensor in detecting the side impact speed, and the probability of misoperation is smaller. Our company has always been committed to the pressure monitoring solution of the air compressor industry. The pressure sensor for air compressors has been at the forefront of the industry after nearly ten years of continuous exploration and research. Our air compressor pressure sensor has the following characteristics: Use dry ceramic core-no risk of oil leakage, no pollution Good economy-competitive prices to meet growing market demand High reliability-can adapt to the harsh working environment of different air compressors Small size-easy to install, convenient for customer integrated maintenance High accuracy-zero point, full range laser calibration can ensure the most stable accuracy output Multi-interface types-to meet customers' different installation needs

At present, there are two main types of pressure sensors in the market, one is the diffusion silicon pressure sensor, and the other is the well-known ceramic pressure sensor. In this issue, we will first to learn the ceramic pressure sensor. Basic characteristics of ceramics Ceramic is a recognized material with high elasticity, corrosion resistance, wear resistance, shock and vibration resistance, and low cost. It is the mainstream development direction of pressure sensor materials. How Ceramic Pressure Sensors Work The ceramic pressure sensor has no liquid transmission. The pressure directly acts on the front surface of the ceramic diaphragm, causing the diaphragm to deform slightly. The back of the ceramic diaphragm is printed with a thick film resistor, which is connected to a Wheatstone bridge. Due to the varistor effect, the bridge is Generates an electrical signal proportional to pressure. According to the core, the ceramic pressure transmitter can be divided into two categories: ceramic piezoresistive and ceramic capacitive. So why do we choose ceramic pressure sensors? Abrasion resistant Ceramics are inherently wear-resistant, and the material is compact, making the ceramic diaphragm 10 times harder than stainless steel. This lightness is advantageous, and it allows the ceramics to withstand harsh environments, including mud, mining and paper production. Corrosion Resistance Two main options are available for measurement applications in highly corrosive processes: special materials, which are often very expensive, or ceramics.Measuring cells made of ceramic resist interaction with the process media very reliably.In contrast to metallic measuring cells, they exhibit significantly increased chemical resistance to many aggressive liquids and gases.So they are therefore compatible with the majority of process media,from salt water to highly acidic liquids. Wide operating temperature range Ceramic high temperature resistance are related with material characteristics , ceramic itself with metal powder and ceramic raw materials sintered materials, sintering temperature is relatively high, so ceramic materials are high temperature resistance. Small size, highly cost-effective The ceramic core is relatively small in structure as a whole, and the pressure sensor designed is also relatively small. Because of its wide application and low cost of mass production, it is liked by customers at home and abroad.

Liquid level sensor is a product to measure liquid level. When you choose a liquid level sensor, you should notice the following things. Know clearly your measured medium Know clearly your application Know clearly your range If you can, know clearly about the parameters of your products.

Positive displacement pump specialist ROBBINS & MYERS has introduced a non-intrusive pressure sensor that protects the pump under dry operating conditions and under high pressure conditions. Designed to fit at the pump outlet, the RM pressure sensor is considered to be the most effective way to prevent the pump from interfering with operation, as opposed to other conventional 'presence / disappearance' detectors, stator temperature probes and other jamming devices. At the same time, positive displacement pumps are considered as one of the most versatile pump designs with the following advantages: They handle abrasive fluids with minimal wear; accurately measure viscous liquids; and deliver extremely sensitive products with major limitations (Just like most pump products) are run dry. However, using RM pressure sensors is one of the most effective ways for users to protect their positive displacement pumps or other processing equipment during dry operating conditions or high / low pressure conditions. The device consists of sensors, pressure switches and control box composed of three basic components. The sensor is mounted between two standard ANSI flanges to allow fluid flow to be unobstructed. Pressure detection throughout the piping system ensures that the enclosure, fixture, or jumper does not affect the pressure reading. A further feature is the presence of a liquid-filled manometer that visualizes the pressure throughout the pump system.
