Dial indicator M476 (M 476, M-476)
 
Dial indicator M476 is designed for use in dc circuits for controlling the recording level and supply voltage of transistor tape recorders.
Vibration, resistant to shaking.
 
Technical characteristics of the instrument dial indicators M476:
 
Current full deflection - 40mkA-300mkA.
The instrument dial gauge M476 is used in ambient temperatures from -10 º C to +45 ° C and relative humidity up to 95% (at 25 ° C).
Current full deflection dial gauge instrument depends on the modification of M476 and requisitions are as follows:
 
Modification of the instrument
M476 / 1
M476 / 2
M476 / 3
M476 / 4
M476 / 5
The current total deviation
40mkA-100mkA
50mkA-150mkA
100mkA-200mkA
150mkA-150mkA
200mkA-300mkA
 
The internal resistance of the instrument dial gauge M476 - 4000 ohms.
Time integration of indicators - 250ms 100ms-.
Scale length - 28mm.
The instrument dial gauge M476 is designed to operate at any position of the scale.
Changing the readings does not exceed ± 5% of full scale value when you reject the ambient temperature of 20 º C ± 5 ° C (class H) for every 10 degrees and under the influence of an external magnetic field of 400 A / m, formed by a constant current in the worst the field direction.
Changing the zero position of the instrument dial gauge M476 influenced placed back to back with him the same indicator, previously located at a distance not less than 1m, less than 0.5 mm.
Dimensions are shown in Fig.
Weight of the device dial gauge M476 - 0,025 kg.
 

 
Housing dustproof and splash-proof design.
Scale of the instrument dial gauge and M476 are two sectors
- From 0 º to 60 ° - sector control the recording level;
- From 60 º to 80 ° - sector control voltage (from 8V to 13V) supply.
The end of the first sector of 60 ° corresponds to the maximum level of recording tape.
The measuring device mechanism dial gauge M476 magnetoelectric system.
The minimum probability of failure of the device for 2,000 hours not less than 0.75 at a confidence level of 0.8.
