Lincoln welding machine ammeter DC ammeter M7980-2 DC1500A, the ammeter works with magnetoelectric effect

The measuring mechanism of magnetoelectric electrical instruments is composed of a fixed magnetic circuit system and movable parts. The magnetic circuit system of the instrument includes a permanent magnet 1, a pole palm 2 fixed at the two poles of the magnet and a cylindrical iron core 3 between the two pole palms. The cylindrical iron core is fixed on the instrument bracket to reduce the magnetic resistance and generate a uniform radial magnetic field in the air gap between the pole palm and the iron core.

The magnetic circuit system of the instrument consists of a permanent magnet 1, a pole palm 2 fixed at the two poles of the magnet and a cylindrical iron core 3 between the two pole palms. The cylindrical iron core is fixed on the instrument bracket to reduce the magnetic resistance and generate a uniform radial magnetic field in the air gap between the pole palm and the iron core. When the movable coil 4 in this magnetic field deflects around the rotation axis, the magnetic fields on the two effective edges are always equal in size and perpendicular to the coil edges. The movable coil is wound on the aluminum frame. The rotating shaft is divided into two parts, one end of each half shaft is fixed on the moving ring aluminum frame, and the other end is supported in the bearing through the shaft tip. The front axle shaft is also equipped with a pointer, which is used to indicate the size of the measured electric quantity when the movable part deflects.

Transparent PC cover, bakelite base, semi transparent cover can be customized according to requirements

Pointer:

The standard instrument pointer is made of aluminum alloy. The black, red and white pointers can be customized according to customer requirements. Setting pointer can be added to indicate the setting value Antistatic treatment:

All instruments are treated with anti-static treatment to reduce the impact of static electricity on the accuracy of the instrument. Damping and overshoot:

Damping and overshoot can be customized according to customer requirements. Generally, when the pointer is set at the position of full scale 23, the overshoot does not exceed 15% accuracy level

Class:1.52.5

working temperature 

-20~50 ℃

Installation position

Unless otherwise specified, the instrument is usually installed in a vertical position. Other positions such as horizontal inclined installation can be customized according to customer requirements. The corresponding accuracy level is only valid for the specified installation position. Precautions:

1 Do not reverse the connection.

2 Do not exceed the measuring range.

3 Pay attention to zero adjustment.

4 Read again after the pointer is stable
