Ratiometer M-64 (M64, M 64; m-64; m64; m 64)
Ratiometer M-64 - magneto-electrical measuring instrument for measuring the ratio of forces of the two electric currents.
Accuracy class - 1.5.
The measurement parameters - 0 - 600 ᵒ C.
Resistance - 5th; 288Om.
Structurally ratiometer M-64 devices are electromagnetic system. Each unit is decorated in the case of a thermoset plastic. On execution of the housing devices are dust-and splash-proof. Ratiometer M-64 is commonly used in devices for measuring the resistance, inductance, capacitance, temperature.
The principle of operation of M-64
The movable part ratiometer M-64 is in the form of two frames arranged perpendicularly. When the Frame ratiometer current flows, the interaction with the magnetic field of the permanent magnet elliptical shape (fixed part ratiometer) creates a torque that moves the arrow tool.
When the currents in the framework of both the M-64 are equal, their torques are equal, the meter pointer is zero. If the currents are different, the movable part of the device is moved so that the box with a large current is in a position with a large gap of a permanent magnet (due to its ellipticity). As a result, the torque generated by the frame, decreases and becomes equal to the torque frame with smaller current.
Placement and installation of M-64
Ratiometer M-64 are designed for flush mounting on vertical or horizontal panels (panels) made as of the magnetic and non-magnetic materials.
When installing the M-64 must adhere to the following rules:
- Installation of equipment should be made carefully, without distortions;
- Fastening ratiometer M-64 on the panel must be rigid and not create additional stress;
- Ratiometer M-64 during assembly should be located away from sources of strong magnetic fields with a strength greater than 0.4 kA / m;
- Appliances intended for inclusion in the network with a voltage of more than 650V, mounted on insulators of reach to touch.
The manufacturer guarantees that the device specification requirements under normal use, storage, transportation and installation. Ratiometer M-64 corresponding to f t requirements ensuring the safety of life, health, consumer and environmental protection.
