Frequency meter shockproof D166

Also, this device can be called: D-166, D 166.

D166 frequency is intended for frequency measurement in AC circuits with a nominal frequency of 50 Hz.

Dimensions - 120×120 mm.

Accuracy class - 0,5.

Shock, vibration and tryaskoprochnye.

Frequency D166 are splash-shield devices ferrodinamicheskoy system. Included in the circuit with a separate extension unit P180.

Scope: installation on ships and mobile installations.

Specifications D166:

Measurement range - 45 Hz to 55 Hz.

Rated voltage:

- The direct inclusion - 127 V, 220 V;

- Via voltage transformer 380 V/127 V - 380 V.

Change readings caused by changes in ambient temperature - no more than ±0,5% for every 10° change in temperature.

Changing testimony from the influence of external magnetic field strength of 5 e - no more than ±0,5% of full-scale.

Scale length D166 - 190 mm.

Grating angle - 230°.

Working part - 100%.

Operating position frequency - vertical.

Housing material - plastic base; steel casing; casing alloy AL2.

Settling time arrow - no more than 3 seconds.

Insulation resistance at ambient temperature (20±5)° C:

- Relative humidity 80% - at least 50 MOhm;

- Relative humidity of 95±3% - less than 2 MOhm.

Weight of frequency D166 - not more than 3 kg.

Frequency D166 constructively arranged in the same splash-proof housing flush mounting. Devices attached to the shield by four studs, embedded in the casing.

Operating conditions D166:

The ambient air temperature - from -40° C to +60° C.

Relative humidity - 98%.

Frequency D166 stand the test:

- By shaking with an acceleration of 70 m/s2 at a frequency of 80 beats per minute to 120 - for 2 hours;

- A vibration at a frequency of 20 Hz with an amplitude of 1,4 mm span - for 2 h;

- On the type copra six strokes of the maximum intensity.
