Counter operating time VSS-2-02 (27B),SVN-1K Maritime counter of operating time

The meter operating time "2 SVN 01" (02 SVN 2) is intended to account for the operation time of equipment, plant, machinery.

Counter SVN-2-01/VSS-2-02 consists of Electromechanical and electronic components. Electromechanical unit includes the display unit of the six digital drums, reducer and stepper motor. The electronic unit is made in the form of a printed circuit Board the suspended elements.

When the power electronic unit forms a bipolar electric pulses with a duration of 31мс, amplitude is not less than 4V, the repetition period of pulses of the same name polarity 2 s. These pulses to the stepper motor, the rotor of which rotates in the beat of each pulse. This rotation is through a gearbox is transmitted to the first the drum, which is an hour makes one revolution. Then, after three transfer on the second drum, the third, fourth, etc. Number on the second the drum represents the number of hours on the third dozens of hours, on the fourth or hundreds of hours, etc.

Counter operating time VSS-1K Maritime

Description and application the time counter SVN-1K:

Counter operating time VSS-1K is designed for automatic recording of operating time.

Counter SVN-1K is designed for operation in conditions of temperate and the tropical climate. Ambient temperature during operation counter from minus 40 to plus 55°C, relative humidity up to 98% at a temperature of 40°C.

The main parameters

• The capacity indicating device, h – 99999,9.
• Time counters in the delivery condition – no more than 4 hours
• Meter weight – not more than 0.5 kg.

Specifications hourmeter SVN-1K:

The accuracy of meter readings EHV-1K does not exceed:

• a) ±0,2% (±7 for one hour of work) in normal climatic conditions according to GOST 15150-69;
• b) ±0,5% (±18 for one hour of work) under the influence of destabilizing factors.
