Current temperature sensor using the matters needing attention

( 1) The better precision of current voltage temperature sensor is under the condition of the original edge rating, so when the measured current is higher than the current rating of temperature sensor, should choose the corresponding big temperature sensor; When the measured voltage is higher than the voltage rating, temperature sensor should readjust current limiting resistor. When the measured current is lower than the rating of 1/2 below, in order to get a better precision, can use more than the number of circle.

（ 2) Insulation withstand voltage of 3 kv temperature sensor can work for a long time in communication system and 1 1 kv and below. Dc system, 5 kv and below 6 kv temperature sensors can work for a long time in communication system, and 2 kv and below 2. Dc system 5 kv and below, be careful not to use overpressure.

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)

temperature sensor in the application of motor current

temperature sensors and motors, drives, controller a motion control system or drive system. Current temperature sensor is commonly used in motor drive and control of the temperature sensor, platinum spark plugs, the output signal is used as a function of protection, feedback, no temperature sensor in the motor control, the current temperature sensor is the indispensable element, the current signal is used to calculate the magnetic field physical quantities such as position and flux linkage and torque. In different kinds of motors even the same type but different in the number of motor drive, the location and type of temperature sensor are also different voltage temperature sensor, temperature sensor, the hall current ( voltage sensor) 。
