TITAN MACHINERY sensors are devices that convert magnetic signals into electrical signals. By utilizing the transformation relationship between magnetic quantities and other physical quantities, with the magnetic field as a medium, they can also convert signals of other non-electrical physical quantities into electrical signals. There are two driving methods: one is driven by a permanent magnet, and the other is driven by an electromagnetic coil. The former is mostly used for detection; for example, if a moving part is made of a magnet, it will attract and emit a signal once it approaches the magnetic induction sensor. The latter is mostly used for control; if the electromagnetic coil is energized, the contacts will attract. Replacing limit switches that rely on collision contact with magnetic induction sensors can improve system reliability and service life; therefore, they are often used in programmable logic controllers (PLCs) as signaling devices for position arrival.

TITAN MACHINERY sensor classification

Load cells are divided into 8 categories based on conversion methods, including photoelectric, hydraulic, electromagnetic force, capacitive, magnetic pole variation, vibratory, gyroscopic, and resistance strain gauge types, with resistance strain gauge being the most widely used. 1) Photoelectric type: Includes grating and code disk types. Grating sensors use Moiré fringes formed by gratings to convert angular displacement into photoelectric signals. 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, which causes 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 sensor: 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 rotates the dial shaft 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 the digital value 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, and the degree of increase is 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 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.

TITAN MACHINERY 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 only very low input energy is required. A large change range can be obtained, resulting in a high signal-to-noise ratio and system stability. The dynamic response is fast, with operating frequencies reaching several megahertz. They support b-contact measurement, and the measured object can be either a conductor or a semiconductor. The structure is simple and highly adaptable, allowing operation in harsh environments such as high and low temperatures and strong radiation, leading to wide application. With the development of electronic and computer technologies, disadvantages of capacitive sensors, such as susceptibility to interference and the influence of 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, thickness, liquid level, humidity, vibration, and component content. Capacitive sensors have promising development prospects.

TITAN MACHINERY sensor installation precautions

1) Handle load cells with care, especially small-capacity sensors using aluminum alloy as the elastic body. 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 axis of the applied load coincides with the force-bearing axis of the load cell to minimize the effects of inclined and eccentric loads. 3) Regarding leveling. If a single load cell is used, adjust the installation plane of its base with a spirit level until it is horizontal. If multiple sensors are used for simultaneous measurement, their base installation surfaces should be kept as level as possible. The main purpose of this is 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 direct sunlight and environments with drastic 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, avoid such situations during installation and use. Even short-term overloading may 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.
