Jaissle Elektronik pressure sensors for liquid level measurement. The static pressure submersible level transmitter (level gauge) is based on the principle that the static pressure of the measured liquid is proportional to its height. It uses advanced foreign isolated diffused silicon sensitive elements or ceramic capacitive pressure sensitive sensors to convert static pressure into electrical signals, which are then converted into standard electrical signals (typically 4 to 20mA/15VDC) after temperature compensation and linear correction.

Jaissle Elektronik 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 accurate and commonly used non-contact laser speed sensors on the market are ZLS-Px aberration speed sensors. The aberration speed sensor has two ports: one emission port that emits a LED light source, and one high-speed photography port that achieves CCD area high-speed imaging comparison. By comparing images at two points in time within an extremely short period, it determines the distance the object has moved and, combined with internal algorithms, 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; upon reflection, the signal is received by the (2) camera reception port and sent to the signal processor, which calculates the speed via algorithm. The ZLS-Px aberration speed sensor can simultaneously measure speed and length in two directions. It not only detects whether the target has stopped but also identifies its direction of motion. Mount the sensor on a stable bracket to ensure that excessive vibration does not occur during the rotation of the object, allowing measurement of the rotational angle and speed of the rotating target. 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, traffic vehicle speed, and golf ball speed. Radar speed sensors can meet these requirements.

Jaissle Elektronik sensor principles

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 becomes very high, resulting in no output signal. Thus, the rotational speed of the measured shaft can be determined based on the number of holes or notches on the disk. The usual number of disk holes or notches is unclear in the source, so the photoelectric converter outputs 60 pulse signals per revolution of the measured shaft. 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 reflective speed sensors is similar to transmissive ones, converting changes in sensed light into electrical signals via a phototube, but they obtain pulse signals through light reflection. Typically, reflective material is applied to the measurement area of the measured shaft to create a reflective surface. Common reflective materials include specialized speed-measuring 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 pulsed light and outputs corresponding electrical signals to the electronic counter, thereby measuring the shaft's rotational speed. The output waveform of photoelectric speed sensors is relatively regular, close to a standard square wave, with almost no interference signals. However, vibration in transmissive types can reduce the lifespan of the light source, making them unsuitable for environments with strong vibrations. Reflective types have no mechanical connection with the measured shaft and are convenient to use.

Jaissle Elektronik 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. Vehicle 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 magnets 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-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 calculation, and graphical or tabular display of test results are increasingly favored by vehicle 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 and graphically display the acquired 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 cost, having good market promotion potential, 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 switch-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 automatic control, computer devices, and modern military technology.
