1,  Unipolar Hall effect switch  (digital output) The unipolar Hall effect switch has a magnetic working threshold (Bop). If the Hall element is subjected to a magnetic flux density greater than the operating threshold, the output transistor will turn on; when the flux density falls below the operating threshold (Brp), the transistor turns off. The lag (Bhys) is the difference between the two thresholds (Bop-Brp). Even if there is external mechanical vibration and electrical noise, this built-in hysteresis page enables the net switch of output. The single-pole Hall effect digital output can be adapted to a variety of logic systems. These devices are ideal for use with simple magnetic bars or magnetic poles. Unipolar Hall switch it is the positive and negative will specify a magnetic pole will have a role in the application, should pay attention to the specific application of the magnetic pole of the installation, anti-will result in unipolar non-sensor output. 2, Bipolar Hall ef

What is a flow rate sensor? A flow meter is an instrument used to measure linear, nonlinear, mass or volumetricflow rate of a liquid or a gas. What is a Flow Meter and how does it work? Overview of Flow Measurement. Flowmeters are devices that measure the amount of liquid, gas or vapor that passes through them. Volumetric flowmeters directly measure the volume of fluid (Q) passing through the flowmeter. The only flowmetertechnology that measures volume directly is the positive displacement flowmeter. What is the use of flow meter? A flow meter is a device used to measure the flow rate or quantity of a gas or liquid moving through a pipe. Flow measurement applications are very diverse and each situation has its own constraints and engineering requirements. Recommended product:  Flow-sensor

What is the use of proximity switch? A proximity switch is a device which causes a switching action without physical contact. SCHMERSAL proximity switches respond to targets that come within the active range of their generated sensing fields. Recommended product A: How do proximity switches work? A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximitysensor's target. Different proximity sensor targets demand different sensors. Recommended product B: What is the meaning of proximity sensor in mobile phones? mobile phones use IR-based proximity sensors to detect the presence of a human ear. This sensing is done for two purposes: Reduce display power consumption by turning off the LCD backlight and to disable the touch screen to avoid inadvertent touches by the cheek.

First, to understand what a gaussmeter is, we need to know what gauss rating means. Gauss is the unit that measures magnetic field B, or magnetic flux density. It was named for the German mathematician and physicist that built the early instrument to measure magnetic fields, Carl Friedrich Gauss. His version was essentially a bar magnet suspended by some string. Gaussmeters today are a little more sophisticated. Magnets are generally given a Gauss rating and can give some clue as to the pulling power. However, it is important to remember that Gauss rating on its own does not fully indicate the strength of a magnet. Although a magnet may have a high Gauss rating, or magnetic flux it may not be as strong as another magnet with a low rating for one particular reason, size. In other words, the actual size of high powered magnets and magnetic flux matter when it comes to magnet strength. If you do want to figure out the gauss rating of a particular magnet. Supplies: Magnets and

Wiegand sensors  are used as a pulse generator in multiple applications. The sensor needs no external power source and has no moving parts. Instead, it exploits the properties of a small diameter wire invented by John Wiegand. When a magnetic field changes the magnetic state of the Wiegand wire within the sensor, a substantial output pulse is produced which can be used as a power source in an energy self-sufficient revolution counter. Wiegand sensor products from POSITAL reflect the knowledge from a full decade of experience using Wiegand-effect base revolution counters. The high performace sensors are assembled using SMD mounting technology and can be used for revolution counters in absolute rotary encoders as well as in other applications, e.g. gas or water meters. Advantages No external power required – No batteries Longer lifespan Operates in harsh environments Non contact measurement – No mechanical wear

A  Hall effect sensor  is a transducer that varies its output voltage in response to a magnetic field. Hall effect sensors are used for proximity switching, positioning, speed detection, and current sensing applications. Application:Position sensing, Direct current (DC) transformers, Automotive fuel level indicator,Keyboard switch. Advantages A Hall effect sensor may operate as an electronic switch. · Such a switch costs less than a mechanical switch and is much more reliable. · It can be operated up to 100 kHz. · It does not suffer from contact bounce because a solid state switch with hysteresis is used rather than a mechanical contact. · It will not be affected by environmental contaminants since the sensor is in a sealed package. In the case of linear sensor (for the magnetic field strength measurements), a Hall effect sensor: · can measure a wide range of magnetic fields · is available that can measure either North or South pole magnetic fields · can be
