Technical data

Maximum permissible error on the measurement and recording of measured value ± 1,0% of full scale range. Maximum permissible error on the record time ± 0,5%. Maximum permissible error on operation in the scope of the pointer device pin ± 1,5% of full scale range.
N3022K devices are made with finite values ​​of the measuring range 5 mA and 20 mA. The internal resistance of the device does not exceed:
1000 Ω - for devices with a finite value of the measuring range, 5 mA;
200 Ω - for devices with a measuring range end value 20mA.
Limit of allowable total error N3022K instruments on the record of measured value ± 1,0% of full scale range. Failure to return a pointer to the zero point of the scale (respectively - writing device to the zero line chart paper) is not more than 1.0 mm.
The discrepancy between the zero line indicated on the chart tape recording with the line when the cursor to the zero mark of the scale does not exceed 0.5 mm. The limit of additional error N3022K instrument for measuring and recording the measured values ​​and alarms caused by changes in the position of devices from its normal position in any direction by ± 5 °, and is equal to the limit of permissible basic error.
Settling time the reading is less than 1 s. Swapping the index value of the first 7% of the width of the field recording.
The insulation between the casing and insulated from the housing all circuits (except for the measuring circuit and applying the time stamp), and between the separate circuits to withstand normal operating conditions for 1 min. test voltage of an alternating current (50 ± 1) Hz, the mean value is 1.5 kV.
The insulation resistance between the case and isolated from the body of any electrical appliance chain N3022K is normally not less than 40 MΩ.
Maximum permissible additional error N3022K device for measuring and recording the measured values ​​and alarms caused by the ambient temperature change from the normal to any temperature between 0 and 50 ° C for every 10 ° C change in temperature equal to:
± 1% of full scale of the measuring range - measurement and recording;
1.5% of the final value of the measuring range - on operation.
The limit of additional error instrument for measuring and recording the measured value under the influence of an external constant homogeneous magnetic field with induction of 0.5 mT at the most unfavorable direction of the magnetic field is equal to ± 1,0% of full scale range.
The limit of additional error N3022K instrument for measuring and recording the measured values ​​and alarms caused by installing it on the ferromagnetic shield thickness (2 ± 0,5) mm, equal to ± 0,5% of full scale range.
The limit of additional error instrument for measuring and recording the measured value and triggering influenced placed back to back with him of the same instrument N3022K, used to be located at a distance of 1 m is equal to ± 0,5% of full scale range. Changing the voltage from minus 15 to plus 10% does not cause additional error.
Warm-up time 1h. Contact device must provide three position control using the output contacts included in the regulating circuit.
The minimum area of ​​regulation device N3022K is a range not exceeding the value of permissible basic error of the instrument by triggering more than 2.5 times. The length scale of the device (100 ± 0,5) mm. Power consumption of the device (including synchronous motor mechanism for moving the chart paper) to 15 V • A.
Speed ​​of the chart paper at normal frequencies are set as follows: 20, 60, 180, 600, 1800, 5400 mm / h Changing speeds performed by change gears.
Overall dimensions 160x160x280mm no more. Flange size less than 160x160 mm. Unit weight of 5 kg.
