The use method and connection method of the ammeter

Rules for the use of ammeter:

①The ammeter must be connected in series with the electrical appliance in the circuit (otherwise it will be short-circuited and the ammeter will be burned.)

How do you look at the voltmeter measurement object And give an example A voltmeter is an instrument for measuring voltage, and the symbol of a commonly used voltmeter-voltmeter is "V". The traditional analog voltmeter includes a sensitive ammeter. There is a permanent magnet in the sensitive ammeter.

What are the photoelectric sensors? Detailed explanation of its working principle wiring diagram The photoelectric sensor is a key element to realize photoelectric conversion in various photoelectric detection systems. It is a device that converts light signals (infrared, visible and ultraviolet radiation) into electrical signals. So what are the classifications of photoelectric sensors?

Working principle of liquid level sensor and wiring diagram The liquid level sensor is also called the liquid level switch, as the name implies, is a switch used to control the liquid level. From the form, it is mainly divided into contact type and non-contact type.

How to wire the pressure sensor and wiring diagram

Pressure sensors are widely used in industrial production. They are a very important production instrument. They are generally composed of sensitive components, transforming components, and measuring components, sometimes with auxiliary power supplies. The output of the pressure sensor is an analog signal.

Types of sensors, application and principle description What is a sensor? A sensor (English name: transducer/sensor) is a detection device that can feel the measured information, and can transform the sensed information into electrical signals or other required forms of information output according to a certain rule to meet the information Requirements for transmission, processing, storage, display, recording and control.

How does the soft starter save energy How to choose its load How does the soft starter save energy? The motor is an inductive load, the current lags the voltage, and most electrical appliances belong to this category. In order to improve the power factor, a capacitive load must be used for compensation, and a capacitor or a synchronous motor must be used for compensation.
