As is well known, the main channel for humans to obtain external information is through sensory organs, among which the eyes, ears, nose, mouth, and limbs play a front-end role. However, with the development of technology and advances in science, in the new state of production and life, human senses are no longer able to meet their needs. In this situation, the birth and application of sensors present enormous value. People view sensors as an extension of human facial features, known as a bridge connecting the physical world and the digital world. In fact, the basic function of sensors is to make objects "come to life". In the context of rapid evolution of automation and informatization, in order to effectively acquire and utilize information and achieve the goal of automation, it is necessary to collect various types of information in the production and life fields through sensors. Whether in the production process or in product application, sensors can effectively "sense" relevant data parameters, thereby controlling the normal and efficient operation of equipment, or providing reference for management, maintenance personnel, and users' operations and decisions. Therefore, in modern industrial and social conditions, the importance of sensors is self-evident. Without sensors, automation…

Oil pressure sensors are widely used in industrial machinery. Today, we will talk about the components of oil pressure sensors. Firstly, the oil pressure sensor mainly consists of three parts: a pressure sensor, a transmission circuit, and an electrical output interface. The basic structure of a voltage sensor is to sense pressure changes through a strip resistor, and at the same time, amplify the resistance changes into a pressure difference through a Wheatstone bridge structure, which is then transmitted to the transmission circuit for filtering, amplification, and other processing. In the process of oil pressure detection, temperature changes are inevitable. Usually, a temperature sensitive resistor is made separately from the four resistance bars of the Wheatstone bridge to synchronously detect the temperature changes in the area where the sensitive resistor is located, providing temperature values for subsequent temperature drift correction. At the same time, in order to prevent the impact of excessive oil pressure, some products have a funnel-shaped inlet at the front end of the pressure tap, which can significantly avoid and reduce the impact of excessive oil pressure [gallery size="full" ids="153,154,155"]

The diffusion silicon pressure transmitter is made by encapsulating isolated silicon piezoresistive pressure sensitive elements in a stainless steel shell.

RPT8100 heavy-duty pressure sensor is a type of sensor, but we rarely hear of this type of pressure sensor. It is commonly used in transportation applications to maintain the performance of heavy-duty equipment by monitoring the pressure, fluid, flow, and liquid level of key systems such as pneumatic, light-duty hydraulic, brake pressure, oil pressure, transmission, and truck/trailer air brakes. A heavy-duty pressure sensor is a pressure measurement device that has a housing, a metal pressure interface, and a high-level signal output. Many sensors are equipped with circular metal or plastic housings, with a cylindrical appearance, one end being a pressure interface and the other end being a cable or connector. This type of heavy-duty pressure sensor is commonly used in extreme temperature and electromagnetic interference environments. Customers in the industrial and transportation fields use pressure sensors in their control systems to measure and monitor the pressure of fluids such as coolant or lubricating oil. At the same time, it can also detect pressure spike feedback in a timely manner, detect system blockages and other issues, and find solutions in real time. Heavy duty pressure sensors have been constantly developing. In order to be used in more complex control systems, design…

2The wiring of sensors has always been one of the most frequently consulted questions during the customer procurement process. Many customers do not know how to wire sensors. In fact, the wiring methods of various sensors are basically the same. Pressure sensors generally have two-wire, three wire, four wire systems, and some even have five wire systems. The two-wire system for pressure sensors is relatively simple, and most customers know how to wire it. One wire is connected to the positive pole of the power supply, and the other wire, which is the signal wire, is connected to the negative pole of the power supply through the instrument. This is the simplest. The three wire system for pressure sensors adds a wire on top of the two-wire system, which is directly connected to the negative pole of the power supply, which is a bit more complicated than the two-wire system. The four wire pressure sensor definitely has two power input terminals, and the other two are signal output terminals. Four wire systems are mostly voltage outputs rather than 4-20mA outputs. 4-20mA transmitters are called pressure transmitters, and most are made into two-wire systems. The signal output of some pressure sensors…

2There are many types of threads for pressure sensors, commonly including NPT PT、G、M， They are all pipe threads. NPT stands for National (American) Pipe Thread, a 60 degree taper pipe thread that is a standard for pressure sensors in the United States and is used in North America National standards can be found in GB/T12716-1991 PT stands for Pipe Thread, which is a 55 degree sealed conical pipe thread belonging to the Wyeth pressure sensor thread family and commonly used in Europe and Commonwealth countries Commonly used in the water and gas pipe industry, the taper is specified as 1:16. National standards can be found in GB/T7306-2000 G is a 55 degree non threaded sealed pipe thread, belonging to the Wyeth pressure sensor thread family The symbol G represents cylindrical thread. National standards can be found in GB/T7307-2001 M is a metric ordinary thread, such as M20 * 1.5, which means a diameter of 20mm and a pitch of 1.5. If the customer has no special requirements, the pressure sensor is generally M20 * 1.5 thread. In addition, the 1/4, 1/2, and 1/8 markings in the thread refer to the diameter of the thread size, measured in inches. Insiders usually…

In many cases, heavy-duty pressure sensors can play their unique role, whether it is providing feedback for the pump pressure of HVAC systems through hydraulic measurement control circuits or measuring the pressure of coolant flow, heavy-duty pressure sensors can output high-level signals. Currently, design engineers are facing the enormous challenge of designing more complex control systems. These systems rely on providing more feedback signals than previous systems. Therefore, design engineers must consider components that meet the requirements of high precision, lower overall cost, and ease of implementation for applications. Currently, control systems mostly use pressure switches for control. This switch opens and closes around a set point, and its output is usually reviewed at the end of the day. This type of system is mainly used for monitoring. Compared with the above control system, the system using pressure sensors can timely and accurately measure pressure spikes, thereby issuing warnings before danger occurs or the control system fails. Sensors connected to computers can measure actual pressure, allowing users to accurately monitor and control the system. Pressure data is generally used to dynamically measure system performance, monitor usage status, and ensure system energy efficiency. A system using sensors can provide more and…

1、Piezoresistive pressure sensor RPT8100 resistance strain gauge is one of the main components of piezoresistive strain sensors. The working principle of metal resistance strain gauges is the phenomenon where the strain resistance changes with mechanical deformation due to adsorption on the substrate material, commonly known as the resistance strain effect.   2、Ceramic pressure sensor Ceramic pressure sensors are based on the piezoresistive effect, where pressure directly acts on the front surface of the ceramic diaphragm, causing slight deformation of the diaphragm. Thick film resistors are printed on the back of the ceramic diaphragm and connected to form a Wheatstone bridge. Due to the piezoresistive effect of the varistor, the bridge generates a highly linear voltage signal that is proportional to the pressure and also proportional to the excitation voltage. The standard signal is calibrated to 2.0/3.0/3.3 mV/V depending on the pressure range, and can be compatible with strain sensors.   3、Diffuse silicon pressure sensor: The working principle of RPT8100, RPT8200, ZY6000, ZY8000 series diffusion silicon pressure sensors is also based on the piezoresistive effect. Using the principle of piezoresistive effect, the pressure of the measured medium directly acts on the diaphragm of the sensor (stainless steel or ceramic), causing the…

We all know that in normal spatial dimensions, there are three dimensions: length, width, and height. However, a tilt angle sensor can measure the tilt angle of these three dimensions. A single axis tilt angle sensor can only measure the angle in a certain direction. The tilt sensor we often refer to generally refers to a single axis tilt sensor, and the theoretical basis of a single axis tilt sensor is Newton's second law. According to basic physical principles, velocity cannot be measured within a system, but its acceleration can be measured. If the initial velocity is known, the linear velocity can be calculated by integration, and then the linear displacement can be calculated. So it is actually an accelerometer that uses the principle of inertia.
