Wiegand Sensor High-Temperature Type Wg414ht

Product Description

Features

1.No need the power supply when it works.

2.Bipolar excitation working mode

The sensor outputs a pair of positive and negative electrical pulse signal when the magnetic field polarity changes for a circle.

3.Non-Contact Electromagnetic Acquisition

No mechanical points or sparks between the magnetic field sensing device and the triggering magnetic field, intrinsically safe device.

4.Constant pulse energy

The value of the pulse energy output from the sensor is independent of the frequency of magnetic field variations and remains constant even at very low magnetic field variations. At higher magnetic field frequencies, higher energy values are generated due to additional inductive effects.

5.Stable working performance

Only when the external magnetic field polarity changes, and magnetic strength reaches the excitationthreshold, the sensor will outputs a pulse signal, so the vibration won't happen. Constant pulse output energy even after millions of transitions. The operation is stable and reliable.

6.LANmanagement

The output signal can be remote transmittedby the signal lines, so it's suitable for LANmanagement.

7.Wide operating temperature range (High temperature is up to 200ºC), strong environmental adaptability.


Principle description
 

Zero power consumption sensoris produced based on Wiegand effect theory, that is, after appropriate treatment of the metallurgical phase of the alloy wire will change, its outer shell coercivity than the inner shell coercivity is much larger, relying on this magnetic difference and a certain amount of applied magnetic field conditions, you can make the inner core of the magnetic field changes in the direction of the outer shell and the direction of this would be the same or the opposite, and with the certain of the external magnetic field can repeat the change of magnetic field, this phenomenon is known as the Wiegand effect. Sensors developed based on this effect are generally known as Wiegand sensors, i.e. zero power magnetic sensors.

Manufactured on the basis of the Wiegand effect, it is capable of actively generating energy, and when in use, without the need for an external power supply, it can generate sharp voltage pulse signals, i.e.,the polarity of the external magnetic field is alternately changed once, and a positive or negative pulse is output to the outside world. The pulses generated can be used not only as a self-powered pulse signal generator, but also to provide energy for ultra-low power devices. This therefore makes zero-power magnetic sensors uniquely suited for low-power and energy-saving applications.

Application

Power-type zeropower consumption magnetic sensoras a passive signal generator can be used for intelligent water meter, flow measurement of heat meter, speed calculation of high -speed tains and electric car, oil level measurement, position detection of tilting rain gauge, etc.
