Dc current recommended temperature sensor manufacturers

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 in the application of motor

temperature sensors and motors, drives, controller a motion control system or drive system. Current temperature sensor is commonly used in motor drive and control of the temperature sensor, platinum spark plugs, the output signal is used as a function of protection, feedback, no temperature sensor in the motor control, the current temperature sensor is the indispensable element, the current signal is used to calculate the magnetic field physical quantities such as position and flux linkage and torque. In different kinds of motors even the same type but different in the number of motor drive, the location and type of temperature sensor are also different voltage temperature sensor, temperature sensor, the hall current ( voltage sensor) 。

current temperature sensor in the control and protection of the door into the system, the application of

the door into the system must provide security and protection for the users. Imagine a garage door locked people or cars in consequence. Current measurements can provide this kind of protection function.

electronic systems control garage doors, shutter and awning is gradually into People's Daily lives, and the protection performance is the most important function of must be taken into account when designing these systems. Current measurements can provide this kind of protection function.

used in garage doors, doors, shutters and awning on dc brush motor, at every time of normal opening and closing to produce its own repeatability of current distribution. The current waveform can be stored in the microcontroller. Current temperature sensor can provide dc brush motor current feedback at work, the door into the system manufacturer defined tolerance range, to that of the current waveform is stored in the microcontroller in the comparison. If the values do not match, the security problems. Micro controller will be alert and closed system or reverse rotation motor, to close the door again. The obstacles, person, or other object provides protection, at the same time protect the motor from damage caused by high current.
