How to measure DC current (high-precision current detection sensor) Dc current detection methods are generally divided into direct type and indirect type, direct type is generally through the series resistance to detect voltage method; Indirect measurement is generally achieved by detecting the magnetic field generated by the current. Since the magnetic field is generated around the current, we can indirectly measure the size of the measured current by measuring the size of the magnetic field. Direct measurement mainly refers to the shunt; Indirect measurement mainly includes Hall current sensor and DC current transformer, the following will mainly introduce the principle and application of these DC current detection methods. How to measure DC current shunt The shunt is a direct measurement method based on the principle of voltage at both ends of a resistor. It has the advantages of high precision, simple structure and low cost. However, the shunt has high requirements for measuring resistance and signal amplification circuit, and the problems of temperature drift and loss of large current limit its application. Application scenario: Applicable when the voltage is low and the current is relatively small. CHIPSENSE is a national high-tech enterprise that focuses on the research and development, production, and application of high-end current and voltage sensors, as well as forward research on sensor chips and cutting-edge sensor technologies.

Hall effect switches are available in various types, each designed to suit specific applications and requirements. The common types of Hall effect switches include: 1.Unipolar Hall Effect Switches: - Digital Output: These switches provide a digital output signal, typically switching between a high and low state (on/off) based on the presence or absence of a magnetic field. - Omni-Polar: Omni-polar switches can detect both north and south magnetic poles, making them versatile for various magnetic field detection applications. 2. Bipolar Hall Effect Switches: - These switches can detect both positive and negative magnetic fields, offering more flexibility in applications requiring bidirectional magnetic field sensing. 3.Latch-Type Hall Effect Switches: - Unipolar Latch: Once activated by a magnetic field, these switches maintain their state (either ON or OFF) until the opposite magnetic field is applied to reset them. - Bipolar Latch: Similar to unipolar latch switches but capable of detecting both positive and negative magnetic fields. 4. Linear Hall Effect Switches: - These switches provide a linear output voltage proportional to the strength of the magnetic field, allowing for more precise magnetic field measurement and detection. 5. Analog Hall Effect Switches: - These switches produce an analog output voltage or current proportional to the applied magnetic field, suitable for applications requiring continuous monitoring and measurement of magnetic fields. 6. Hall Effect Gear Tooth Sensors: - Specifically designed for gear tooth sensing applications, these switches detect the presence or absence of ferrous targets, commonly used in automotive and industrial applications for speed and position sensing. 7. Hall Effect Proximity Sensors: - These switches detect the presence of a magnetic field and are commonly used for proximity sensing applications, such as detecting the opening and closing of doors, windows, or lids.

Check out our Highly accurate speed sensor with optional DAKKS calibration (DIN EN ISO/IEC 17025). Rotational-Speed Sensor | vSpeedBox Highly accurate speed sensor with optional DAKKS calibration (DIN EN ISO/IEC 17025). The vSpeedBox allows to measure speed without any tacho inputs and with a normal DC input. Inside the vSpeedBox, the input pulses coming from the LED-Sensor are used to measure the signal period with high accuracy based on 16 MHz time base. The speed values are calculated and converted to an speed-proportional analog DC output voltage, so they can be recorded by any data acquisition system with a DC input. Parallelly the impulse from the LED-Sensor are routed through to the TTL-Output, so data acquisitions having a special tacho input can be used as well. To guarantee a high accuracy, three speed ranges can be selected: Advantages & Innovation High accuracy tachometer with DC output Speed ranges: 400 RPM, 4000 RPM, 40000 RPM High precision analog voltage output (12 bit = 4096 values) TTL output (pulse/rev) DAKKS (ISO 17025) – calibration optional Integration into existing measurement and monitoring systems Optical sensor with M16 thread Simple sensor assembly #maultheet #speedsensor #rotationalspeedsensor #vspeedbox #testbench #eigenfrequency #automatichammer #damping #modal #vibrationmeasurement #impacthammer #laserdopplervibrometer #forcecell #qualitycontrol #endofline #modalhammer #naturalfrequency #resonacefrequency #dampingmeasurement #modaldamping #vibrationteststand learn more: https://lnkd.in/ee8dhrJ7

Inductive proximity sensor Vs Capacitive proximity sensor ★An inductive proximity sensor is a sensing device that detects metal targets using electromagnetic energy and without contact. The sensing range of an inductive proximity sensor changes based on the type of metal being detected. Since non-metallic substances such as dirt and liquid do not interfere with detection, an inductive proximity sensor operates in wet or dirty conditions. ★Capacitive proximity sensors are non-contact devices that can detect the presence or absence of virtually any object regardless of material. They use the electrical property of capacitance and the change of capacitance based on a change in the electrical field around the active face of the sensor. Capacitive sensing technology is often used in various detection tasks:- * Flow * Pressure * Liquid level * Spacing * Thickness * Ice detection * Shaft angle or linear position * Dimmer switches * Key switches * X-y tablet * Accelerometers

#MassFlowControl is essential for processing metals. Controlling the mass flow process means #ControllingTheWidth of the #RollGap so that the material thickness of the final product remains as constant as possible. If the thickness before the roll stand and the velocity before and after the roll stand are known, the roll gap, which determines the thickness of the rolled product, can be adjusted in accordance with the desired conditions.   Optical sensors from Polytec measure length and process speed without contact but with interferometric precision, while avoiding slippage, wear and uncertainty. They offer digital and analogue output signals for the PLC just like any classic encoder and are easy to integrate.   Find out more: https://lnkd.in/euMdS3RK
