Current temperature sensor manufacturer reliable quality assured

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)

the difference between the voltage transformer and current temperature sensor detection current

current transformer, is the primary side large current, in proportion to fit through the instrument or use the relay, rated current 1 a to 5 a or the transformation of equipment. Its working principle and the transformer is similar.

1, a winding and high voltage circuit in series, only depends on the high pressure loop current, which has nothing to do with the secondary load.

2, secondary loop is not allowed to open, otherwise it will produce dangerous high voltage, endangers one's personal and equipment safety.

3, secondary loop must have some grounding directly, prevent after the primary and secondary windings insulation breakdown of high voltage, but only a little ground.

the current temperature sensor has the advantage of this structure is simple, accuracy and linearity of the measurement result is higher. Measurable dc, ac and all kinds of current waveform. But its measuring range, such as bandwidth is limited by certain. In this application, hall device is magnetic field detector, it detects the magnetic core air gap of the magnetic induction intensity. After current increase, core may reach saturation; With increasing frequency, magnetic core in eddy current loss, hysteresis losses, etc. It will rise. These will have an effect on the measurement accuracy. Of course, also can take some improvement measures to reduce these effects, such as choosing high saturation magnetic induction intensity of magnetic core materials; Made from multilayer magnetic core; Multiple hall element is used to test and so on.

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.
