German CASTELLANI STAMPI sensors, CASTELLANI STAMPI models, CASTELLANI STAMPI prices

CASTELLANI STAMPI pressure sensors for level measurement. Submersible static pressure level transmitters (level gauges) operate on the principle that the static pressure of the measured liquid is proportional to its height. They use advanced imported isolated diffused silicon sensitive elements or ceramic capacitive pressure sensitive sensors to convert static pressure into electrical signals. After temperature compensation and linear correction, these are converted into standard electrical signals (typically 4 to 20mA/15VDC).

CASTELLANI STAMPI 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. The most common and high-precision non-contact laser speed sensors on the market today are ZLS-Px aberration speed sensors. Aberration speed sensors have two ports: one emission port that emits LED light source; and one high-speed imaging port that achieves CCD area high-speed imaging comparison. By comparing images at two points in time within an extremely short period, the distance moved by the measured object is determined. Combined with internal algorithms, the sensor 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. (1) The LED light emission port directs laser at the measured object; upon reflection, it reaches the (2) camera reception port. The received signal is sent to the signal processor, which calculates the speed using algorithms. ZLS-Px aberration speed sensors can simultaneously measure speed and length in two directions. They can detect not only whether the measured object has stopped but also its direction of motion. Mount the sensor on a stable bracket to ensure that the rotating object does not generate excessive vibration during rotation, allowing measurement of the rotation angle and rotational speed of the measured 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.

CASTELLANI STAMPI 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, and no signal is output. 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 signal changes via a phototube. However, they obtain pulse signals through light reflection, typically by attaching reflective material 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. Sometimes, white paint is applied to the measured 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 waveform of the output signal from 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 light source's lifespan, making them unsuitable for environments with strong vibrations. Reflective types have no mechanical connection with the measured shaft and are convenient to use.

CASTELLANI STAMPI 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 magneto-electric sensor based on the Hall effect, It features 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-structure speed sensors include: high-level output voltage, low-level output voltage, duty cycle, period, rise time, fall time, and number of pulses per cycle, 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. It is 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, 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 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 and automatic control, computer devices, and modern military technology.
