German AECO sensors, AECO models, AECO prices

AECO sensors, also known as torque sensors, torsion sensors, torque transducers, or torque meters, are divided into two main categories: dynamic and static. Dynamic torque sensors are also referred to as torque transducers, torque-speed sensors, non-contact torque sensors, or rotary torque sensors. Torque sensors detect the twisting moment on various rotating or non-rotating mechanical components. They convert the physical changes in torsional force into precise electrical signals. Torque sensors can be used in the manufacture of viscometers and electric (pneumatic, hydraulic) torque wrenches. They offer advantages such as high precision, fast frequency response, high reliability, and long service life.

AECO sensor industry applications

AECO 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 applied by 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, which alters the magnetic flux density on the splines. This change in magnetic flux density is converted into a voltage signal via coils. Due to their non-contact operating mode, non-contact torque sensors have a long service life, high reliability, resistance to wear, lower latency, and are less affected by shaft deflection and axial offset. They are 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 previously used for output signals in contact strain gauge sensors can now be replaced by wireless transmission modules. This overcomes wear between slip rings and brush arms, improving measurement accuracy. Magneto-electric torque sensors operate on the principle of magneto-electric conversion, analyzing the phase difference between two electromotive force output signals to measure torque. They are mainly categorized 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 source changes accordingly, causing a change in the output current of the photoelectric element. Measuring this change allows calculation of the torque value. [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, thereby achieving 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 sends it to the transmission module. Upon receiving the data, the receiving module's decoder translates the data and sends it 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 uses an encoder to encode and process the collected information data, which is then transmitted by the emission module, achieving wireless transmission. 4) Electronic sensors 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. Innovatively discarding the cumbersome, complex, and often impractical installation process of traditional electromechanical torque sensors, the electronic torque meter enables real-time measurement of fan and water pump motor efficiency. It monitors the operational status of fan and water pump motors at various stages during use, providing real-time, authentic, and reliable data for studying their usage conditions. This avoids the impact of improper installation of electromechanical torque sensors on test results. 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.

AECO sensor usage precautions

1) During installation, do not operate while energized. Do not directly strike or collide with the sensor. 2) Tighten the coupling's fastening bolts securely. Install a protective cover on the outside of the coupling to prevent 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 routine metrological verification and calibration work, torque sensors are typically calibrated using a torque standard machine. Since torque sensors have high accuracy, usually Class 1 or higher, another important factor affecting measurement results, 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, making connection reliability an inevitable issue. Previously, rigid connections were often used to ensure stability and firmness during installation. This method caused many inconveniences for inspectors during assembly and disassembly. Additionally, due to machining precision and fit gaps of components, the coaxiality between measurement shafts varied significantly during actual measurement, seriously affecting the accuracy of results. Although this defect can be reduced using laser alignment devices, factors such as various influences and differences in manual installation skills mean that coaxiality remains a significant source of uncertainty during the actual loading process of torque sensors.
