PRIORCLAVE sensors, also known as displacement sensors, are a type of sensor used to detect the distance to an object to perform a preset function, and have been widely applied. Main products include mobile phone proximity sensors and long-distance measurement sensors, which are applied in smart belts. Proximity sensors can be divided into optical proximity sensors, infrared proximity sensors, ultrasonic proximity sensors, and others based on their working principles. Most proximity sensors used in mobile phones are infrared proximity sensors, which feature an infrared emitting tube and an infrared receiving tube. When the infrared light emitted by the transmitting tube is received by the receiving tube, it indicates that the distance is close, and the screen needs to be turned off to prevent accidental operation. When the receiving tube does not receive the infrared light emitted by the transmitting tube, it indicates that the distance is far, and there is no need to turn off the screen. The working principles of other types of proximity sensors are similar; they also determine distance by emitting and receiving a certain substance, such as ultrasonic waves or light pulses.

PRIORCLAVE sensor classification

1) Non-contact torque sensors In non-contact torque sensors, the input shaft and output shaft are connected by a torsion bar. The input shaft has splines, and the output shaft has keyways. When the torsion bar twists under the torque from the steering wheel, the relative position between the splines on the input shaft and the keyways on the output shaft changes. The change in relative displacement between the splines and keyways equals the twist amount of the torsion bar, causing a change in magnetic flux density on the splines. This change in magnetic flux density is converted into a voltage signal through a coil. Due to their non-contact operating mode, non-contact torque sensors have long service life, high reliability, are less prone to wear, have smaller delay, and are less affected by shaft deflection and axial offset. They have been widely used in the passenger car sector. Common types of non-contact torque sensors include strain gauge, magneto-electric, fiber optic, and photoelectric sensors. Strain gauge non-contact sensors utilize wireless transmission technology. With advancements in technology and wireless transmission, the conductive slip rings and brush arms used for output signals in contact strain gauge sensors can now be replaced by wireless transmission modules, thereby overcoming wear between slip rings and brush arms and improving measurement accuracy. Magneto-electric torque sensors operate on the principle of magneto-electric conversion, analyzing the phase difference of electromotive force signals from two outputs to measure torque. They are mainly divided into closed magnetic circuit sensors and open magnetic circuit sensors. Fiber optic torque sensors primarily use light reflection and phase difference principles. They read light signals reflected from two corresponding positions on the shaft and calculate the phase difference to determine the torque value. However, fiber optic sensors are susceptible to environmental influences, and installation and debugging are relatively difficult. Photoelectric torque sensors use photoelectric sensing elements as core components. When torque is applied to the drive shaft, the intensity of light emitted by the light source changes accordingly, causing a change in the output current of the photoelectric element. The torque value can be calculated by measuring this change. [3] 2) Strain gauge torque sensors Strain gauge sensors use strain electrical measurement technology for torque measurement. Strain gauges are bonded to the elastic shaft to form a measurement bridge. When the elastic shaft undergoes slight deformation due to torque, the resistance of the bridge changes. This change in resistance is converted into an electrical signal change to achieve torque measurement. The sensor performs the following information conversion: it consists of an elastic shaft, a measurement bridge, an instrumentation amplifier, and an interface circuit. 3) High-performance wireless sensors High-performance wireless torque sensors combine sensors with wireless communication technology to achieve wireless data transmission. The torque electrical signal is amplified and undergoes A/D conversion by a microcontroller-controlled signal processing circuit. An encoder then encodes the collected digital data and transmits it to the transmission module. After the receiving module receives the data, a decoder sends the decoded data to the microcontroller, which displays the obtained torque data value via LED. The sensor data acquisition and transmission circuit consists of the torque sensor, signal processing section, microcontroller, and wireless transmission circuit. The torque sensor transmits the strain electrical signal generated by the resistance strain gauges to the signal processing circuit. The signal processing section extracts and amplifies the analog signal from the sensor and performs analog-to-digital conversion. The microprocessor controls the operation of various components in the system and processes the digital signals. Under the control of the microprocessor, the wireless transmission circuit encodes and processes the collected information data via an encoder and transmits it using the transmission module to achieve wireless transmission. 4) Electronic sensors Electronic torque meters are portable, high-performance shaft power measuring instruments designed for fan and water pump testing and on-site energy efficiency evaluation. Electronic torque meters creatively eliminate the cumbersome, complex, and often difficult installation process of traditional electromechanical torque sensors in many field environments. They enable real-time measurement of fan and water pump motor efficiency, monitor the operational status of fan and water pump motors during use, and provide real-time, authentic, and reliable data for studying the usage status of these motors. This avoids the impact on test results caused by improper installation of electromechanical torque sensors. Electronic torque meters can completely replace the shaft power measurement function of traditional torque sensors and obtain the real-time efficiency of fan and water pump motors, providing a rigorous and scientific evaluation method for energy saving in fan and water pump units.

PRIORCLAVE sensor usage precautions

1) During installation, do not operate while energized. Do not directly strike or collide with the sensor. 2) The fastening bolts of the coupling must be tightened, and a protective cover should be added to the outside of the coupling to avoid personal injury. 3) The signal line output must not be shorted to ground or to the power supply. The output current must not exceed 10mA. The shield layer of the shielded cable must be connected to the common terminal (power ground) of the +15V power supply. 4) In daily metrological verification and calibration work, torque sensors are usually calibrated using torque standard machines. Since torque sensors have high accuracy, typically 1 class and above, another important factor affecting measurement results in actual measurement work, besides the uncertainty of the torque standard machine itself, is the connection quality between the sensor and the torque standard machine. Especially in the calibration of high-precision torque sensors, when not considering the uncertainty of the torque standard machine itself, the quality of the connection will directly affect the accuracy of the measurement results. In existing torque sensor measurement methods, sensors are usually connected in series with the torque standard machine for calibration, so issues regarding the reliability of connection quality inevitably arise during calibration. In the past, to ensure the stability and firmness of the connection installation, rigid connections were typically used. This method brought many inconveniences to inspectors during assembly and disassembly. Additionally, due to the machining precision of parts and the existence of fit clearances, the coaxiality between the measurement shaft systems changed significantly during actual measurement, seriously affecting the accuracy of the measurement results. Although this defect can be reduced by laser alignment devices, due to various influencing factors and differences in manual installation levels, coaxiality remains a major uncertainty factor in the metrology process during actual loading of torque sensors.
