Analogue instruments Analogue instruments In many applications, such as control and distribution panels, it is important to control the installation quickly and visu-ally, with no need to interpret data to de-tect the installation's status. CIRCUTOR offers a solution to these needs with this range of products. Analogue indicators are essential to display an instantaneous electrical value with a needle that moves through a graduated scale. Definition The main operation of these instruͭments is provided by the type of measurement system used, either a ferromagnetic system to measure...

Analogue instruments 777.7 the coil. This system is used to measure AC and DC voltage and current between 15 and 100 Hz and it measures the root mean square of alternating current. It can not be used to measure rectified and unfiltered AC currents.Magneto-electric (DC) The magneto-electric indicator is com-posed of a permanent central magnet, surrounded by a magnetic casing that guarantees the insensitivity to the exte-rior magnetic field and there is a mov-ing coil between both, where the nee-dle is fixed. Two spiral springs create the antagonistic pair to move the nee-dle on the scale...

Auxiliary power supply The tolerance accepted for the nominal auxiliary power supply values is: voltage: -15 ... +10 % frequency: 45 ... 65 Hz Vibrations The instruments and their accessories support a minimum vibration with an amplitude of ±0.25 mm and a frequency of 50 cycles. Said vibration is equivaͭlent to the application of an acceleration equal to 2.5 g to the three perpendicular axes during 20 minutes. Degree of protection Under normal operating...
