German GERT MALIK sensor GERT MALIK model GERT MALIK price

GERT MALIK 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 are widely applied. Main products include mobile phone proximity sensors and long-distance measurement sensors, applied in smart belts. Proximity sensors can be classified into optical proximity sensors, infrared proximity sensors, ultrasonic proximity sensors, etc., based on their working principles. Most proximity sensors used in mobile phones are infrared proximity sensors, which have 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 a short distance, requiring the screen 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 a long distance, and the screen does not need to be turned off. The working principles of other types of proximity sensors are similar, judging distance by the emission and reception of a substance, such as ultrasonic waves or light pulses.

GERT MALIK sensor classification

1) Non-contact torque sensor In a non-contact torque sensor, 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 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 via a coil. Due to the non-contact operating mode, non-contact torque sensors have long service life, high reliability, are less prone to wear, have lower delay, and are less affected by shaft deflection and axial offset, making them widely used in the passenger car sector. Common types of non-contact torque sensors include strain gauge, magnetoelectric, 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 be replaced by wireless transmission modules, overcoming wear between slip rings and brush arms and improving measurement accuracy. Magnetoelectric torque sensors use the principle of magnetoelectric 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 mainly use the principles of light reflection and phase difference. 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 from the 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 sensor 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, measurement bridge, instrumentation amplifier, and interface circuit. 3) High-performance wireless sensor 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 encodes the collected digital quantity and transmits it to the transmission module for sending. After the receiving module receives the data, the 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 part, microcontroller, and wireless transmission circuit. The torque sensor transmits the strain electrical signal generated by the resistance strain gauge to the signal processing circuit. The signal processing part extracts and amplifies the sensor's analog signal 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, achieving wireless transmission. 4) Electronic sensor An electronic torque meter is a portable, high-performance shaft power measuring instrument designed for fan and water pump testing and on-site energy efficiency evaluation. The electronic torque meter creatively eliminates the cumbersome, complex, and often difficult installation process of traditional electromechanical torque sensors in many field environments. It enables real-time measurement of fan and water pump motor efficiency, monitors the operational status of fan and water pump motors during use, and provides real-time, authentic, and reliable data for studying their usage status. It avoids the impact on test results caused by improper installation of electromechanical torque sensors. The electronic torque meter 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.

GERT MALIK sensor usage precautions

1) During installation, do not operate while energized. Do not directly strike or collide with the sensor. 2) Tighten the fastening bolts of the coupling. Add a protective cover to the outside of the coupling to avoid personal injury. 3) The signal line output must not be grounded or short-circuited 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 a torque standard machine. Since torque sensors have high accuracy, typically Class 1 and above, another important factor affecting measurement results in actual 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 directly affects the accuracy of the measurement result. In existing torque sensor measurement methods, the sensor is usually connected in series with the torque standard machine for calibration, so issues regarding the reliability of the connection quality inevitably arise during calibration. In the past, to ensure the stability and firmness of the connection installation, rigid connections were usually used. This method brings many inconveniences to inspectors during loading and unloading. Additionally, due to the machining precision of parts and the existence of fit clearances, the coaxiality between the measuring shaft systems changes significantly during actual measurement, seriously affecting the accuracy of the measurement result. 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 metrological process during actual loading of the torque sensor.
