German MA TER sensor, MA TER model, MA TER price

MA TER 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 sensors, 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, offering advantages such as high precision, fast frequency response, good reliability, and long service life.

MA TER sensor classification

1) Laser speed measurement: With the rise of precision manufacturing and the need for cost savings, non-contact speed sensors are gradually replacing contact-type speed sensors. The most common and high-precision non-contact laser speed sensor currently 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 target 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 and linear motion speed. However, industrial automation often requires irregular speed measurements, such as athlete speed measurement, traffic vehicle speed measurement, and golf ball speed measurement. Radar speed sensors can meet these requirements.

MA TER 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 passes through the holes or notches to illuminate the phototube. When illuminated, the phototube's reverse resistance drops significantly, outputting an electrical pulse signal. When the disk blocks the light source, the phototube's reverse resistance becomes very high, and no signal is output from the terminal. 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 each revolution of the measured shaft results in the photoelectric converter outputting 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, converting changes in sensed 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. Common reflective materials include specialized speed-measurement reflective tape; aluminum foil or other reflective materials can also be used, and sometimes white paint is applied to the measurement area as a reflective surface. The projector and reflective surface must be properly configured, typically with a distance of 5-15M between them. As the measured shaft rotates, the photoelectric element receives pulsating light and outputs corresponding electrical signals to the electronic counter, thereby measuring the shaft's rotational speed. 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, vibration can reduce the lifespan of the light source in transmissive types, making them unsuitable for environments with strong vibrations. Reflective types have no mechanical connection with the measured shaft and are convenient to use.

MA TER 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 these devices require the vehicle speed signal. Therefore, The accuracy and stability of the output signal from the sensor measuring vehicle running speed will have a significant impact on these control units. Automotive speed sensors mostly adopt a Hall-effect structure, A Hall speed sensor is a magnetoelectric sensor based on the Hall effect, Characterized by high sensitivity to magnetic fields, stable output signal, high frequency response, strong resistance to electromagnetic interference, 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 rotates under external drive, It drives the permanent magnets to rotate, The magnetic field passing through the Hall element undergoes periodic changes, Causing changes in the output voltage of the Hall element, Which is processed by subsequent circuits to form a stable pulse voltage signal, Serving as the output signal of the vehicle speed sensor. The main electrical technical parameters of Hall-structure speed sensors include: high-level output voltage, low-level output voltage, duty cycle, period, rise time, fall time, number of pulses per cycle, etc. To ensure product performance reliability, These parameters must be quantitatively tested before leaving the factory. Test systems featuring integration and intelligence, efficient automatic measurement, software computation, and graphical or tabular display of test results are increasingly favored by automotive speed sensor manufacturers. A comprehensive testing device developed for performance measurement of commonly used Hall-effect vehicle speed sensors. Considering cost, The high-speed counter port of a microprocessor is used for data acquisition from the vehicle speed sensor, Software control is utilized to compute the acquired data and process it for graphical display. 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 cost, And has good market potential for widespread adoption, Therefore, speed sensors have significant application prospects in vehicle speed detection. 2) The speed sensor of the belt conveyor adopts a Hall sensor, which is primarily a sensor that utilizes the Hall effect to achieve magneto-electric conversion, The Hall effect has a development history of more than 100 years since it was discovered in 1879, but its application began in the 50s of this century, Due to the rapid development of microelectronics, it has gained attention and widespread adoption, and various types of Hall elements have been continuously developed. China began to increase research on Hall elements in the 70s of the 20th century, After nearly several decades of research and development, it is now possible to produce Hall elements with various performance characteristics, such as: standard type, high sensitivity type, low temperature coefficient type, temperature and magnetic measurement type, and switching type Hall elements. Due to the characteristics of Hall sensors, such as high sensitivity, good linearity, high stability, small size, and high temperature resistance, they have been widely applied in various industrial fields, including automatic control for non-electrical quantity measurement, computer devices, and modern military technology.
