Current temperature sensor using the matters needing attention

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 output

current temperature sensor using the output type depends on the application and operating environment.

- analog voltage signal The temperature sensor output analog voltage signals. - analog current level The temperature sensor output analog current signal. It can be used for signal transmission standard 4 - 20mA。 - switch and the voice signal Temperature sensor can be connected to the switch or voice alarm, the alarm by noise or process changes indicate current levels. - modulation frequency output Current temperature sensor can output the following list of any frequency output. Sine wave pulse train amplitude modulation ( AM） FM ( FM） Pulse width modulation ( 脉宽调制)

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.
