Technical characteristics
Emf at 20 ° C with:
Release of production from 1.019000 to 1.019600 V;
Operating from 1.018800 to 1.019600 V
Tolerance emf for 1 year. no more than ± 100 mV. temperature conditions of use: normal (20 ± 5) ° C, working from 5 to 50 ° C. Relative Humidity of 80%. Temperature calibration n. e. 20 ° C.
Average temperature coefficient in the temperature range from 10 to 40 ° C does not exceed 5 mV / ° C, and at temperatures ranging from 5do 10 ° C and from 40 to 50 ° C - 10mkV / ° C.
The internal resistance of the device normal element ME4700 DC at output, not more than 1000 ohms. The increase in internal resistance n. e. ME4700 during the first year of service, up to 500 ohms, for the life - no more than 1000 ohms.
The insulation resistance between the electrical circuit BC ME4700 and its case in the working conditions of application of not less than 10 G W. Electrical isolation between the electrical circuit and teplovyravnivayuschim and protects the body shell n. e. ME4700 in the working conditions of use stand for 1 minute. test voltage of 250 V of substantially sinusoidal waveform and frequency of 50 Hz.
Electrode size (cross-sectional branches H-shaped glass envelope) is not less than 50 mm 2. Probability of failure-free operation during 8760 hours in the working conditions of application of at least 0.87. Overall dimensions of no more than 78x47x24 mm. Weight not more than 0.15 kg.
The total content of precious materials in the device normal element ME4700: Pl-99.9 - 0.0354477, the total content of non-ferrous metals: copper wire MM0.25 - 0.09 g; brass L63 - 2.5 g
Note: For information on the locations of the components that comprise the non-ferrous metals, the manufacturer sends the customer's request.
