Closed loop current temperature sensor price recommended source

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.

current temperature sensor - — Electromagnetic compatibility

electromagnetic compatibility EMC, ( 电- - - - - - 磁兼容性) Is the study of electrical and electronic equipment that can perform their respective functions in common electromagnetic environment state of coexistence, the requirements of the various devices in the same electromagnetic environment can work normally and noninterference, achieve 'compatibility' state a discipline. The deterioration of space electromagnetic environment is more and more easy to make electronic components caused by incompatible between false action in the system, so the electrical and electronic equipment electromagnetic compatibility testing is very necessary. Due to the urgent needs of the actual production, scientific research and marketing, has passed the electromagnetic compatibility test a consensus has emerged among current and voltage of temperature sensor, and has become a compulsory standards.

the current temperature sensor and temperature sensor with different characteristics?

temperature sensor is able to be measured by rules and convert the available output signal according to certain rules to the sum of the device or devices, he is made up of two parts, namely, respectively is sensitive components and conversion components. The sensitive element refers to the temperature sensor can feel directly or part of the response is measured; Conversion element refers to the temperature sensor will be sensitive element in feeling or response is measured into electrical signal part of the suitable for transfer or measurement.

when the temperature sensor output is the standards prescribed by the signal, is known as temperature sensor.

temperature sensors is to convert the target signal to standard electrical instrument or equipment, the temperature sensor is a physical signal into electrical signal devices, physical signals used to speak, now there are other signal.

in general current temperature sensor output signal is consistent with the measured signal waveform, is proportional to the relationship. The current temperature sensor is on the basis of the current temperature sensor through adjustment of the circuit will originally followed signal transformation became with the original edge current proportional relationship to the size of the dc signal being measured ( Voltage or current signal) Such as, DC 4 - 20mA, DC 0- 5 v直流0 - 10 v signal, etc. The signal can be standard industrial control products such as PLC, RTU, DAS card, AD collection module acquisition received directly, so normally the auxiliary power supply current temperature sensor is also commonly used DC24V dc power to industrial market.
