Three-phase alternating current temperature sensor price is recommended

Current temperature sensor application

current temperature sensor has a wide variety of applications. For example, some equipment is used for power metering and control system for diagnosis, measurement and control the complex load of the motor current supply. Other used in rechargeable battery state of charge integration and monitoring. Special current temperature sensor ( Current temperature sensor used for commercial devices, for example) Usually has a safe cutting function and surge tripping. Also provides high voltage current temperature sensor. Installed on the PCB's current temperature sensor combines the advantages of cover an area of an area small and can be realized by using the existing microprocessor signal processing advantages.

type selection reference current temperature sensor element

1, what is the output, current or voltage, such as the output voltage is 4 v.

2, and accurately determine the temperature sensor, some need high accuracy, so emphasize accuracy when the choice, choose high precision current temperature sensor.

3, the specifications of the auxiliary power - Alternating current temperature sensor in order to accurately detect the change of input current current temperature sensor, and also to the dc signal output to the input current into a linear change, usually requires an auxiliary power supply for the current temperature sensor working power supply, such as power supply voltage of power supply voltage, + 15 v.

the main characteristic parameters of current temperature sensor

1, the offset current ISO

the offset current is also known as the residual current and residual current. This is mainly by the hall element or operational amplifier caused instability in the electronic circuit. When the current temperature sensor manufacturing under 25 ° C and IP = 0, the offset current will change, but when off the line, the temperature sensor produces a certain amount of the offset current.

2, standard rating IPN and rated output current ISNIPN refers to the standard temperature sensor can test the current rating. It is composed of RMS ( 一个。 r。 m。 s） Said. The size of the IPN associated with temperature sensor product model. ISN refers to the rated output current, current temperature sensor is generally 10? 400mA。 Of course, this may be owing to the different models.

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.
