Shaanxi fiber alternating current temperature sensor factory product introduction

Current temperature sensor description

small fusion power equipment has been more and more new technology. For example, switching power supply, hard switching, soft switch, voltage regulator, linear feedback regulator, magnetic amplifier technology, numerical control, PWM, SPWM voltage regulator, electromagnetic compatibility and so on. Actual demand directly boost power technology development and progress continuously, in order to automatically detect and display current, and the over-current, over-voltage and other dangerous happens with automatic protection function and higher level of intelligent control, with sensing monitoring, sampling, sensing protection of power technology is a trend, the temperature of the test current or voltage sensor arises at the historic moment and gets gradually the favour of the general power supply designers in our country.

select current temperature sensor note

of the specifications of the auxiliary power.

alternating current temperature sensor in order to accurately detect the change of the input current, also in order to be output to the input current into dc signal of linear change, usually need a auxiliary power supply more current temperature sensor work power, in general, choose AC220V is more easy to obtain, can also choose to dc power supply, such as: DC24V, etc. , it is important to note that some of the current temperature sensor, that does not need auxiliary power supply, the so-called 'passive' current temperature sensor.

current temperature sensor characteristic parameters on the motor protection

1, the temperature sensor voltage VA.

the VA means the power supply voltage, pay attention to the power supply voltage should not exceed the prescribed values, if more than a specified value can lead to equipment detection performance is low, or equipment can't normal operation.

2, the standard rating ISN IPN and rated output current.

in general current IPN value of the temperature sensor is the detection rating, different models is different, ISN refers to the rated output current, output current usually between 100 ~ 400 m current temperature sensor A, when trying to choose need to choose according to need.

3, overload.

the overload ability of the actual current temperature sensor, when more than current overload condition, the original and current will increase, while the overload of the actual value, but will not affect to equipment.

4, Ipmax measuring range.

Ipmax means to measure the current value, this value is usually higher than that of IPN, users need to pay attention to when choosing a current temperature sensor belongs to the single-phase power supply, power supply voltage it is 2 times of bipolar power supply voltage.

5, precision.

the precision of the equipment, is also considering a big general accuracy directly and standard rated current is related.

hall temperature sensor

AIC is the abbreviation of 'integrated circuit', which is quickly developed in the late eighty s a high-tech products. From the design thought, research methods, until the test method, with the traditional general IC has a qualitative difference, is the very large scale integrated circuits ( VLSI) Technology, computer aided design ( CAD) , automatic test technology ( 吃了) Combination of fruitful results. Application on the temperature sensor, is the special thick film circuit temperature sensor. ASIC circuit temperature sensor temperature sensor of the conversion circuit and output circuit ( Most of the electronic circuit) All integrated on a custom chip, greatly reduce the number of components, the temperature sensor only CT and PT, power supply, large capacitance, ASIC chip, such as a few devices, which can greatly improve the reliability of the temperature sensor and long-term stability.
