Q144-BC Q96-BC Q72-BC Q48-BC Voltmeter DC

Overview

Q144-BC Q96-BC Q72-BC Q48-BC Voltmeter DC is measure the effective value of DC voltage，Overall dimensions...... din43700, Comply with marine codes and IEC standards. The selection of the commonly used DC voltmeter DC is the same as that of the DC ammeter.  It is applicable to ships, power systems, locomotives, petrochemical industry, mining machinery, underground engineering, mobile power stations, nuclear power stations, oil platforms, mechanical equipment, etc. it has a wide range of applications. There are 21 kinds of imported products with complete specifications and can be expanded. It can be used for the measurement of AC and DC power.If a shunt is used, the shunt must be used together with the ammeter. The zero point of its scale is generally placed on the far left of the dial. The instrument not only has advanced electronic technology, reasonable product structure and excellent product quality, but also has beautiful appearance, light weight, mechanical resistance and environmental climate resistance. The imported products comply with IEC international standards and have obtained the approval certificate of French by classification society and American ABS classification society.

Working principle of Q144-BC Q96-BC Q72-BC Q48-BC Voltmeter DC

In order to measure the voltage in our actual circuit, we need to connect a relatively large resistance in series with this voltmeter to make a voltmeter. this Sample, even if two ends are added_ The voltage on the meter is relatively large, but most of the voltage acts on the large resistance we added, and the voltage on the meter will be very small. It can be seen that the voltmeter is an instrument with large internal resistance, which - generally should be greater than thousands of ohms.

There is a magnet and - a wire coil in the voltmeter. After passing the current, the coil will produce a magnetic field. In this way, the coil will rotate under the action of magnet after being energized

This is the meter head of ammeter and voltmeter.
