German BRILEX sensors, BRILEX models, BRILEX prices

BRILEX sensors are measurement feedback devices that operate based on the optical principle of gratings. Grating scales are frequently used in the closed-loop servo systems of CNC machine tools and can be used to detect linear or angular displacement. The measurement output signal is a digital pulse, characterized by a large detection range, high detection accuracy, and fast response speed. For example, in CNC machine tools, they are often used to detect the coordinates of tools and workpieces to observe and track tool path errors, thereby compensating for the motion errors of the tool. Grating scales are divided into transmission gratings and reflection gratings according to different manufacturing methods and optical principles.

BRILEX sensor classification

Load cells are classified into 8 types based on conversion methods, including photoelectric, hydraulic, electromagnetic force, capacitive, magnetic pole variation, vibratory, gyroscope, and resistance strain gauge types, with resistance strain gauge types being the most widely used. 1) Photoelectric type: Includes grating type and code disk type. Grating sensors convert angular displacement into optoelectronic signals using Moiré fringes formed by gratings. There are two gratings: one fixed grating and one moving grating mounted on the dial shaft. The measured object placed on the weighing platform rotates the dial shaft through the force transmission lever system, driving the moving grating to rotate and causing the Moiré fringes to move accordingly. Using a phototube, conversion circuit, and display instrument, the number of moved Moiré fringes can be calculated to measure the angle of grating rotation, thereby determining and reading the mass of the measured object. Code disk sensors: The code disk (symbol plate) is a piece of transparent glass mounted on the dial shaft, featuring black and white codes arranged according to a specific encoding method. When the measured object on the weighing platform causes the dial shaft to rotate via the force transmission lever, the code disk also rotates by a certain angle. A photocell receives the light signal passing through the code disk and converts it into an electrical signal, which is then digitally processed by the circuit, finally displaying a number representing the measured mass on the display. Photoelectric sensors were mainly used in electromechanical combination scales. 2) Hydraulic type: When subjected to the gravity P of the measured object, the pressure of the hydraulic oil increases, with the degree of increase proportional to P. By measuring the increased pressure value, the mass of the measured object can be determined. Hydraulic sensors have a simple and robust structure and a large measurement range, but the accuracy generally does not exceed 1/100. 3) Capacitive type: It operates based on the direct proportional relationship between the oscillation frequency f of the capacitor oscillator circuit and the distance d between the plates. There are two plates, one fixed and the other movable. When the measured object is loaded onto the weighing platform, the leaf spring deflects, changing the distance between the two plates, which in turn changes the oscillation frequency of the circuit. By measuring the change in frequency, the mass of the measured object on the weighing platform can be calculated. Capacitive sensors consume little power, have low cost, and have an accuracy of 1/200 to 1/500.

BRILEX sensor features

Resistors, inductors and capacitors are the three major categories of passive components in electronic technology. A capacitive sensor is a sensor that converts changes in the measured quantity into changes in capacitance; it is essentially a capacitor with variable parameters. Capacitive sensors have the following advantages: high impedance, low power, and requiring only very low input energy. They can achieve large change magnitudes, thereby providing a high signal-to-noise ratio and system stability. Fast dynamic response, with operating frequencies reaching several megahertz; suitable for b contact measurement, and the measured object can be either a conductor or a semiconductor. Simple structure and strong adaptability, allowing operation in harsh environments such as high and low temperatures and strong radiation, with wide application. With the development of electronic technology and computer technology, the disadvantages of capacitive sensors, such as susceptibility to interference and influence from stray capacitance, have been continuously overcome. Furthermore, capacitive grating displacement sensors and integrated capacitive sensors have been developed. Therefore, they are widely used in non-electrical quantity measurement and automatic detection, capable of measuring parameters such as pressure, displacement, rotational speed, acceleration, A degree, thickness, liquid level, humidity, vibration, and component content. Capacitive sensors have promising development prospects.

BRILEX sensor installation precautions

1) Handle load cells with care, especially small-capacity sensors with aluminum alloy elastic bodies. Any impact or drop caused by vibration is likely to cause significant output errors. 2) When designing the loading device and during installation, ensure that the line of action of the loading force coincides with the force axis of the load cell to minimize the effects of inclined and eccentric loads. 3) Regarding level adjustment. If using load cells, the installation plane of the base must be adjusted to horizontal using a spirit level. If multiple sensors are used for simultaneous measurement, their base installation surfaces should be kept as level as possible to ensure that the force borne by each sensor is basically consistent. 4) Determine the rated load of the sensor used based on the load cell capacity selection specified in its instructions. 5) To prevent chemical corrosion, apply Vaseline to the outer surface of the load cell during installation. Avoid use in locations with direct sunlight exposure and drastic environmental temperature changes. 6) Install bypasses made of copper braided wire at both ends of the load cell loading device. 7) Do not extend the cable yourself. If extension is absolutely necessary, solder the joints and apply moisture-proof sealant. 8) It is best to use baffles to cover the sensor around the load cell. This prevents debris from falling into the moving parts of the sensor, which could affect its measurement accuracy. 9) Keep the sensor's cable away from high-power power lines or places with pulse waves. If avoidance is impossible, run the load cell cable separately through an iron pipe and shorten the connection distance as much as possible. 10) Determine the rated load of the sensor used based on the load cell capacity selection specified in its instructions. Although load cells have a certain overload capacity, such situations should be avoided during installation and use. Short-term overloading may sometimes cause permanent damage to the sensor. 11) For high-precision applications, allow the load cell and instrument to warm up for 30 minutes before use.
