Current temperature sensor using the matters needing attention

( 1) The better precision of current voltage temperature sensor is under the condition of the original edge rating, so when the measured current is higher than the current rating of temperature sensor, should choose the corresponding big temperature sensor; When the measured voltage is higher than the voltage rating, temperature sensor should readjust current limiting resistor. When the measured current is lower than the rating of 1/2 below, in order to get a better precision, can use more than the number of circle.

（ 2) Insulation withstand voltage of 3 kv temperature sensor can work for a long time in communication system and 1 1 kv and below. Dc system, 5 kv and below 6 kv temperature sensors can work for a long time in communication system, and 2 kv and below 2. Dc system 5 kv and below, be careful not to use overpressure.

use 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.
