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.

current temperature sensor is introduced

current temperature sensor mainly through measurement on the current path resistance pressure drop to monitor current circuit ( Although there are other techniques, such as magnetic technology, but the discussion here is limited to parallel resistance current measurements) 。

a and by measuring the current temperature sensor output current is proportional to the voltage or current of the path. Thanks to it's widely used to measure current. Traditionally, the current sensor is mainly used for circuit protection and reports, but with the development of technology, current of induction as a means of monitoring performance and become increasingly important, and the purpose of monitoring performance is improved.

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.

USES current temperature sensor module note

current temperature sensor will direct current voltage power frequency signals, such as isolation into a 4 - 20mA/0- 10 v, etc all kinds of standard signal on both ends of the semiconductor chip to control the current I, and applying magnetic induction intensity in the vertical direction of the wafer for B and strong magnetic field, is in the direction perpendicular to the current and magnetic field, will produce the electric potential difference as UH voltage.

when measuring current, the use of single wire temperature sensor module aperture, in order to get a better dynamic performance and sensitivity.

the better accuracy of the temperature sensor module was measured under rating, when measured value is lower than the rating, the original with many winding coils, the total ampere turn close to the rating, in order to gain a better measurement accuracy.

when use current temperature sensor module, vice side should be connected to the power supply, then turn on the primary side current or voltage. Current bus temperature shall not exceed 100 degrees.

when choosing temperature sensor module, according to the measuring range, accuracy, reaction time and the parameters such as connection mode, choose different models of temperature sensor.
