Wattmeter D5094 small cosine (hereinafter - watt meters) single-phase, portable, electrodynamic system with a moving part on extensions are designed to measure power in alternating current at power factor of 0.1 to 1 in DC circuits, as well as for use as model checking devices at less accurate power meter.
Wattmeter D5094 is used mainly for magnetic measurements in determining the losses in ferromagnetic materials testing machines and devices in idle mode, stroke, etc.
D5094 are designed for use in moderate climate in enclosed dry heated rooms with ambient in Creating the ear from 10 to 35 ° C and a relative humidity of 60% at a temperature of 25 ° C.
D5094 04.1-watt meters are designed for use in both dry and humid tropical climate in closed rooms with air conditioned or partially air-conditioned at the ambient temperature from 1 to 45 ° C and humidity of tnositelnoy to 50% at a temperature of 25 ° C.
D5094 power meter accuracy is class 0 and 5 in accordance with GOST 8475-78. Basic watt meter D5094 decree us in the table. Rated power factor of 0.1 watt meter. Current branch circuit power meter (5 ± 0,1) mA. Normal range of frequencies from 45 to 65Hz. Operating frequency range from 150 Hz to 500 Hz. Response time is less than 3s.
Maximum permissible error in the normal Oblasov minute frequency with a coefficient of resistance from 0.1 to 1.0 and at a constant current is ± 0,5% of the final value of the measuring range.
The limit of additional error-watt meter wattmeter D5094 small cosine frequency deviation from the upper limit of normal values to any frequency in the working frequency range is ± 0,5% of the final value of the measuring range.
The limit of additional error-watt meter D5094 caused by changes in ambient temperature on the rate of flax to any temperature within the limits established following operating conditions, for every 10 ° C is ± 0,5% of full scale diameter pazona measurements. The normal temperature of 20 ° C if the front of the power meter otherwise stated value. (Tolerance ± 2 ° C)
AC voltage (220 ± 22) h Frequency of 50-60Hz through a step-down transformer, can be combined with the power meter, or about t AC or DC voltage (4 ± 0,4) B.
In WATTMETER D5094 supplied under specific orders, the voltage and frequency of the supply chain in light of St. etovogo indicators meet in order. Dimensions: power meter - (205 ± 1,45) x (290 ± 1,6) x (135 ± 2, 0) mm, transformer, no more - 65h85h45 mm. Weight, power meter - 4.3 kg, transformer - 0.5 kg.
