Magnetic tachometer

Magnetic tachometer


This device indicates velocity by employing the effect of eddy currents to distort a magnetic field. Magnetic tachometers are used in ship's engine, turbine's, moulding machines, centrifuges, mining industry and in many others.

Additional information

Magnetic tachometers can work with moto hour meters. Meter's measuring range is 10 ÷ 99.999,990 rotations. Meters count the rotations irrespective of their direction. Clients ordering magnetic tachometers, receive technical data chart from Mera Poltik which they have to fill in and submit when placing the order.

Technical data

Diameter of a dial:
750/... 100, 130, 160, 200 mm
751/... 80, 100, 130, 160, 200 mm
Rotary speed of a driving shaft:
For tachometers indicating rotation in one way 300...6000 rotations/min
For tachometers indicating rotation in two ways 260...6000 rotations/min
(rotary speed of a driving shaft to a value indicated on the dial)
according to the orders but with keeping the rotary speed of a driving shaft
Admissible error:
Ambient temperature 0...50°C ±1% upper value of indication
Ambient temperature 0...20°C ±2% upper value of indication
