A measure of the resistance measuring R4023

R4023 measuring coil resistance are designed for use as a single-valued measures electrical resistance (OMES) in DC.
Operating conditions:
ambient temperature (20 ± 5) ° C;
relative humidity from 25 to 80% in the working temperature range;
84-106.7 kPa atmospheric pressure (630-800 mm Hg).

Type of climate UHL 4.1 per GOST 15150-69.
Coil resistance measurement R4023 belongs to the non-renewable, one-channel, monofunctional products.

Technical characteristics

The main parameters of the coils R4023 and OKP codes are given in the table below. The permissible deviation of the actual value of the coil resistance of the nominal value of R4023 for initial verification (at release from the factory) is not greater than ± 0,01% under the following standard conditions:
ambient temperature (20 ± 0,5) ° C;
relative humidity (25-80)%;
atmospheric pressure 64-106,7 kPa (630-800 mm. mercury);
current is constant;
voltage is higher than the nominal (stated in the table)
Restricted to change the coil resistance R4023 per year (instability) does not exceed ± 0,005%. The limit of additional error R4023 coil caused by changes in ambient temperature between the upper (lower) limit the range of normal conditions of use and by some point in the related field of application of the operating temperature corresponding to the maximum change in resistance, Kmax is equal to ± 0,005%. The resistance value (Rt) coil in ohms at
t ° C operating temperature range is determined by the formula.
The limit of additional error R4023 coil as a percentage of its nominal voltage changes from nominal to any value that does not exceed the maximum, under normal conditions of use and steady thermal state does not exceed ± 0,005.
Average, MTBF coil R4023 least 30,000 hours in the working conditions of use. Average life of coils at least 10 years. For information about the content of precious metals of silver: 0.28 g
