German Actionair sensors, Actionair models, Actionair prices

Actionair sensors, also known as torque sensors, torsion sensors, torque sensors, and torque meters, are divided into two main categories: dynamic and static. Among these, dynamic torque sensors are also referred to as torque sensors, torque-speed sensors, non-contact torque sensors, and rotary torque sensors. Torque sensors detect the twisting moment on various rotating or non-rotating mechanical components. They convert the physical changes in torque 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, good reliability, and long service life.

Actionair sensor classification

1) Laser speed measurement: With the rise of modern precision manufacturing and the need for cost savings, non-contact speed sensors are gradually replacing contact speed sensors. Currently, the most common and high-precision non-contact laser speed sensor on the market is the ZLS-Px aberration speed sensor. The aberration speed sensor has two ports: one emission port that emits a LED light source, and one high-speed imaging port that achieves CCD area high-speed imaging comparison. By comparing images taken at two instants within an extremely short time, the distance moved by the measured object is determined, and the sensor's internal algorithms output the object's speed in real time. As shown in the figure, (1) is the LED light emission port, (2) is the camera reception port, (3) and (4) are the terminal blocks, and (5) are the mounting screw holes. The (1) LED light emission port directs laser light at the measured object; after reflection, it reaches the (2) camera reception port. Upon receiving the signal, it is transmitted to the signal processor, which calculates the speed using algorithms. The ZLS-Px aberration speed sensor can simultaneously measure speed and length in two directions. It not only detects whether the measured object has stopped but also identifies its direction of motion. Mount the sensor on a stable bracket to ensure that the rotation of the object does not generate excessive vibration, thereby allowing accurate measurement of the rotational angle and speed of the rotating object. 2) Radar speed measurement: Traditional speed measurement mostly involves rotary motion speed measurement and linear motion speed measurement. However, there are many irregular speed measurement scenarios in industrial automation, such as athlete speed measurement, traffic vehicle speed measurement, and golf ball speed measurement. Radar speed sensors can meet these requirements.

Actionair sensor principle

A transmissive speed sensor consists of a slotted or notched disk, a light source, and a phototube. When the disk rotates with the measured shaft, light can only reach the phototube through the holes or notches. When the phototube is illuminated, its reverse resistance is very low, resulting in the output of an electrical pulse signal. When the light source is blocked by the disk, the phototube's reverse resistance is very high, and no signal is output. Thus, based on the number of holes or notches on the disk, the rotational speed of the measured shaft can be determined. The usual number of disk holes or notches is unclear in the source, so when the measured shaft completes one revolution, the photoelectric converter outputs 60 pulse signals. If the time base signal of the electronic counter is set to 1s, the rotational speed of the measured shaft can be read directly. The principle of a reflective speed sensor is similar to that of the transmissive type; it converts changes in received light into electrical signal changes via a phototube, but it obtains pulse signals through light reflection. Typically, reflective material is adhered to the measurement area of the measured shaft to form a reflective surface. Commonly used reflective materials include special speed-measuring reflective paper tape (adhesive tape), or aluminum foil and other reflective materials may be used as substitutes. Sometimes, white paint can be applied to the measured area to serve as a reflective surface. The projector and the reflective surface must be properly configured, typically with a distance of 5-15M between them. When the measured shaft rotates, the photoelectric element receives pulsed illumination and outputs corresponding electrical signals to the electronic counter, thereby measuring the rotational speed of the shaft. The waveform of the output signal from photoelectric speed sensors is relatively regular, close to a standard square wave, with almost no interference signals generated. However, since vibration can reduce the lifespan of the light source in transmissive types, they are not suitable for conditions with strong vibrations. Reflective types have no mechanical connection with the measured shaft and are convenient to use.

Actionair sensor industry applications

1) Modern vehicles are generally equipped with engine control, autonomous driving, ABS, TRC, automatic door locking, active suspension, guidance systems, electronic instruments, and other devices, all of which require vehicle speed signals. Therefore, the accuracy and stability of the output signals from speed sensors will greatly impact these control units. Automotive speed sensors often adopt a Hall-effect structure. A Hall speed sensor is a magnetoelectric sensor based on the Hall effect, featuring high sensitivity to magnetic fields, stable output signals, high frequency response, strong anti-electromagnetic interference capability, simple structure, and ease of use. It mainly consists of permanent magnets with a specific number of pole pairs (generally 4 or 8 pairs), Hall elements, a rotating mechanism, and input/output connectors. Its working principle is that when the sensor's rotating mechanism is driven externally, it rotates the permanent magnet, causing periodic changes in the magnetic field passing through the Hall element. This induces changes in the output voltage of the Hall element, which are processed by subsequent circuits to form stable pulse voltage signals as the output of the speed sensor. Key electrical technical parameters for Hall-structure speed sensors include high and low output signal voltages, duty cycle, period, rise time, fall time, and pulses per period. To ensure product performance and reliability, these parameters must be quantitatively tested before factory release. Test systems featuring integration and intelligence, efficient automatic measurement, software calculation, and graphical or tabular display of results are increasingly favored by automotive speed sensor manufacturers. A comprehensive testing device has been developed for performance measurement of commonly used Hall-effect vehicle speed sensors. Considering costs, the high-speed counter port of a microprocessor is used for data acquisition from the vehicle speed sensor, and software control is employed to calculate and graphically display the collected data. The completed testing device offers advantages such as high testing precision, reliable data communication, a user-friendly graphical interface, strong anti-interference capability, a simple and intuitive testing process, and low system development costs. It has good market promotion potential, indicating significant application prospects for speed sensors in vehicle speed detection. 2) Speed sensors for belt conveyors use Hall sensors, which are sensors that utilize the Hall effect to achieve magnetoelectric conversion. The Hall effect was discovered in 1879 and has a development history of over 100 years. However, its application gained attention and widespread adoption in the 50s of this century due to the rapid development of microelectronics, leading to the continuous development of various Hall elements. China began increasing research on Hall elements in the 20s of the 70 century. After nearly several decades of research and development, it is now possible to produce Hall elements with various performances, such as standard type, high-sensitivity type, low-temperature-coefficient type, temperature/magnetic-field measuring type, and switch-type Hall elements. Due to the characteristics of Hall sensors—high sensitivity, good linearity, high stability, small size, and high-temperature resistance—they are widely used in various industrial fields, including non-electrical quantity measurement and automatic control, computer devices, and modern military technology.
