Current temperature sensor manufacturer company recommended by the manufacturer

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 using note

1. In order to get a better dynamic characteristics and sensitivity, must pay attention to the original coil and deputy while coil coupling, coupling well, available single wire and wire completely fill the hole temperature sensor module aperture;

2. Used as the dc current flows through the temperature sensor of the original side coil, and the secondary circuit without | stabilizer or vice side open circuit, power supply is connected, the magnetic circuit is magnetized, remanent magnetization, the influence and measuring accuracy, So use to connect the power supply and measure the end M) , when this happens, first to demagnetization. The method is a circuit without power, and by the same level in the primary side coil alternating current and decreases the size of its value;

current temperature sensor in the control and protection of the door into the system, the application of

the door into the system must provide security and protection for the users. Imagine a garage door locked people or cars in consequence. Current measurements can provide this kind of protection function.

electronic systems control garage doors, shutter and awning is gradually into People's Daily lives, and the protection performance is the most important function of must be taken into account when designing these systems. Current measurements can provide this kind of protection function.

used in garage doors, doors, shutters and awning on dc brush motor, at every time of normal opening and closing to produce its own repeatability of current distribution. The current waveform can be stored in the microcontroller. Current temperature sensor can provide dc brush motor current feedback at work, the door into the system manufacturer defined tolerance range, to that of the current waveform is stored in the microcontroller in the comparison. If the values do not match, the security problems. Micro controller will be alert and closed system or reverse rotation motor, to close the door again. The obstacles, person, or other object provides protection, at the same time protect the motor from damage caused by high current.

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.
