Dc current temperature sensor factory product introduction

An overview of the current temperature sensor

( 1) Output end concentrated by large electrolytic and noise reduction

( 2) 1 n4004 capacitance uF, diode.

（ 3) Transformer according to the power consumption of the temperature sensor.

（ 4) The temperature sensor's working current. Direct detection ( No amplification) Power: big to 5 ma; Straight test amplified power consumption: big to + 20 ma; Magnetic compensating power consumption: 20 output current; Consumption of working current 20 2 times the output current. According to the working current consumption power consumption can be calculated.

the characteristics of the current temperature sensor

both open loop and closed loop hole temperature sensor principle, basic performance difference is not big, basic advantage: fast response time, low temperature drift, high precision, small volume, wide frequency band, strong anti-jamming capability, overload ability.

how selection - — Current temperature sensor

A, choose current temperature sensors need to pay attention to the hole size can ensure wire can be through the temperature sensor;

B, choose current temperature sensor when the need to pay attention to the application environment for high temperature, low temperature, high humidity, earthquake and other special environment;

C, choice when need to pay attention to the space structure whether meet the current temperature sensor.

the classification of the current temperature sensor

current temperature sensor on the basis of measuring principle is different, the main can be divided into: the shunt, electromagnetic current transformer, electronic current transformer, etc.

including hall current temperature sensor, Luo Kefu electronic current transformer, current temperature sensor and is dedicated to frequency conversion power measurement AnyWay frequency conversion power temperature sensor ( Can be used for the voltage, current and power measurement) And so on.

current temperature sensor is also called magnetic temperature sensors, can be in household appliances, smart grid, electric vehicles, wind power, etc. , are used in our life a lot of magnetic temperature sensors, such as computer hard drives, compass, household appliances and so on.

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.
