German WARME MESS sensor, WARME MESS model, WARME MESS price

WARME MESS sensors, also known as torque sensors, torsion sensors, torque meters, are divided into two main categories: dynamic and static. Among them, dynamic torque sensors are also called torque sensors, torque-speed sensors, non-contact torque sensors, rotating torque sensors, etc. 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, electric (pneumatic, hydraulic) torque wrenches. They offer advantages such as high precision, fast frequency response, good reliability, and long service life.

WARME MESS 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 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 at two extremely close time points, it determines the distance the object has moved. Combined with internal algorithms, it outputs 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 terminal blocks, and (5) are mounting screw holes. The (1) LED light emission port directs laser at the target object; after reflection, the signal is received by the (2) camera reception port and sent 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 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 cause excessive vibration, allowing accurate measurement of the rotation angle and speed of the rotating object. 2) Radar speed measurement: Traditional speed measurements mostly focus on rotational and linear motion speeds. However, industrial automation often involves irregular speed measurements, such as athlete speed tracking, vehicle traffic speed monitoring, and golf ball speed measurement. Radar speed sensors can meet these requirements.

WARME MESS Sensor Principle

Transmissive speed sensors consist 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 increases, resulting in no output signal. Thus, based on the number of holes or notches on the disk, the rotational speed of the shaft can be determined. The usual number of disk holes or notches is unclear in the source, so each revolution of the shaft generates 60 pulse signals from the photoelectric converter. If the electronic counter's time base signal is set to 1s, the shaft speed can be read directly. The principle of reflective speed sensors is similar to transmissive ones, converting light changes into electrical signals via a phototube. However, they obtain pulse signals through light reflection, typically by attaching reflective material to the measurement area of the shaft to create a reflective surface. Common reflective materials include specialized speed-measuring reflective tape (adhesive tape), aluminum foil, or even white paint applied to the measurement area. The emitter and reflective surface must be properly aligned, usually maintaining a distance of 5-15M. As the shaft rotates, the photoelectric element receives pulsating light and outputs corresponding electrical signals to the electronic counter, thereby measuring the shaft's rotational speed. Photoelectric speed sensors produce relatively regular waveforms, close to standard square waves, with minimal interference. However, transmissive types may suffer reduced light source lifespan due to vibration, making them unsuitable for high-vibration environments. Reflective types have no mechanical connection with the shaft, offering ease of use.

WARME MESS 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 vehicle speed sensor 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 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 rotates under external drive, it drives the permanent magnet to rotate, causing the magnetic field passing through the Hall element to change periodically, which causes the output voltage of the Hall element to change, forming a stable pulse voltage signal through subsequent circuit processing, serving as the output signal of the vehicle speed sensor. The main electrical technical parameters of Hall-effect speed sensors include: high-level output voltage, low-level output voltage, duty cycle, period, rise time, fall time, number of pulses per period, 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 calculation, 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, and software control is used to calculate 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, having 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 its discovery 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 capable of producing 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 non-electrical quantity measurement and automatic control, computer devices, and modern military technology.
