485 first company of service of manufacturer of alternating current temperature sensor

Using the current temperature sensor are places which need to pay attention to?

* pay attention to the auxiliary power supply information on product labels, the temperature sensor of auxiliary power level and polarity is wrong, otherwise will damage the temperature sensor;

* current direction and shell be the same as the arrow marked on the products, to achieve positive output;

* the original edge bus should not exceed 60 ℃, the temperature of current bus when threading hole to fill the original edge, obtain better measurement accuracy;

* this series of temperature sensor is not set internal lightning protection circuit, when the temperature sensor input, output, feeder exposed to outdoor environment of the bad weather, lightning protection measures should be paid attention to;

* temperature sensor is integrated structure, sealed, avoid collision and fall at the same time.

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 output

current temperature sensor using the output type depends on the application and operating environment.

- analog voltage signal The temperature sensor output analog voltage signals. - analog current level The temperature sensor output analog current signal. It can be used for signal transmission standard 4 - 20mA。 - switch and the voice signal Temperature sensor can be connected to the switch or voice alarm, the alarm by noise or process changes indicate current levels. - modulation frequency output Current temperature sensor can output the following list of any frequency output. Sine wave pulse train amplitude modulation ( AM） FM ( FM） Pulse width modulation ( 脉宽调制)

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.
