The current temperature sensor anti-interference

electromagnetic field

closed loop hall effect current temperature sensor, using the original wire of electromagnetic field theory. Thus the following factors directly affect the temperature sensor is affected by external electromagnetic interference.

( 1) Temperature sensor near the external current size and current frequency change;

( 2) Outer conductor and the distance of the temperature sensor, the external shape, location, and the temperature sensor of the wire inside hall of electrode position;

( 3) Installation temperature sensor used by material with and without magnetic;

( 4) Temperature sensor is used by the current block;

in order to minimize the interference of external electromagnetic field, according to the installation guide to install the temperature sensor.

the application of the current temperature sensor

with the continuous development of modern industrial technology, the current widely used in the field of industrial control, industrial control of electric current detection precision and response speed of the demand is higher, at the same time hope completely isolated and tested object implementation, current temperature sensor has solved these problems well. Current temperature sensor for its excellent performance and ingenious structure, has become the field of industrial control current isolation measurement solutions, and is widely used in the drive, and high frequency inverter, motor winding current measurement, etc.

current temperature sensor - — Technology introduction

current temperature sensor using technology is important, because different temperature sensor may have different characteristics in various applications. Most of the temperature sensor can work, because the current-carrying wire creates a magnetic field. When directly measure the current in the circuit, will use the current sense resistor.

induction - Induction temperature sensor using a coil, the current-carrying conductor through the coil. This leads to the power flowing in the coil, is proportional to the current. This is due to the flow of electric current of magnetic fields. Induction temperature sensor is used for alternating current. The temperature sensor has a line around the core and signal conditioner. When the current through the conductor core conductor magnetic field will enlarge it. Due to alternating current constant electric potential from negative to positive, Usually for 50 to 60 Hz) Expand and contract, so will produce magnetic field, so the current is induced in the winding. Voltage and secondary current is converted to be adjusted for the output process. 4 - signal, for example 20 ma or contact closure.

magnetic resistance - Magnetic resistance effect is some material to change its resistance value as a function of the applied in its magnetic field characteristics. If it is not applied to magnetic flux, the current will directly through the plate. If the imposed magnetic flux and magnetic flux density is proportional to the lorentz force will make current path deflection. As the current path deflection, current flows through the plate distance is longer, resulting in increased resistance.
