Overall dimensions - 80 × 80 × 130 mm.
Vibration, impact resistant, splash-proof.
The main structural unit E8004 device is measuring mechanism, consisting of a mobile system, the magnetic circuit of the block.
Frequency E8004 have an outer shield to reduce the influence of external magnetic fields.
Frequency E8004 admits error in the measurements, the limit of which is at all elevations scale ± 1,0%.
Also, frequency counters E8004 influenced by various factors may allow the following error:
- If the provisions of the frequency deviation from the normal position in any direction by 45 ° - equal to the value of the maximum permissible basic error.
- Voltage deviates by ± 10% of nominal, is the value of the maximum permissible basic error;
- When the ambient temperature of (20 ± 5) ° C and any temperature within the range of from minus 50 ° C to 60 ° C at every 10 ° C change in temperature, the power of 0.5 of the maximum permissible values of the basic error.
Power consumption - less than 7 watts. Service life - 2 years. The assigned resource in normal operating conditions - 50,000 hours.
Frequency counter E8004 is designed to operate under the following conditions:
- Ambient temperature from -50 ° C to +60 ° C;
- Relative humidity: - 30% -80%.
Positioning and mounting of E8004
Frequency counter E8004 are designed for flush mounting on vertical or horizontal panels (panels) made as of the magnetic and non-magnetic materials.
When installing the E8004 must adhere to the following rules:
- Installation of equipment should be made carefully, without distortions;
- Frequency counters E8004 mount on the panel must be rigid and not create additional stress;
- E8004 frequency counter during installation 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. Frequency E8004 meets the requirements for ensuring safety of life, health, consumer and environmental protection.
