Potentiometer PP-63

PP-63 potentiometer DC is designed for direct measurement compensation method, EMF and voltage, calibration in workshop conditions technical thermocouple and secondary thermal instrumentation operating with thermocouples (pyrometric millivoltmeters and automatic potentiometers), obtaining a smoothly regulated the DC voltage.

The potentiometer PP-63 used with galvanometer M2031/2

Technical characteristics of PP-63:

Measuring range - from 0 to 25 mV, 0 to 50 mV; 0 to 100 mV.

Class of accuracy 0,05.

Maximum permissible basic error PP-63 at a temperature of from +15° C to +25° C, where U is the reading of the potentiometer Umin - the scale of slidewire - ±(5·10-4U +0,5·Umin)%.

The price of division of the scale of slidewire to the limit:

- "×0,5" - 2,5·10-5 In;

- "×1" - 5·10-5 In;

- "×2" - 10·10-5 V.

The change of the readings of the potentiometer when the temperature of the ambient air in the range from +10° C +35° C for every 5° C change in temperature - not more than 1/4 of the permissible basic error.

The range of variation of the voltage of the variable voltage source at a voltage of 1.2 V and external load is not less than 25 Ohm - not less (-1,25)-0-(+25) mV; not less than (-2,5)-0-(+50) mV; not less than (-5)-0-(+100) mV.

The lowest level of voltage regulation of PP-63, from the limit voltage value is not more than 0,03%.

The internal resistance of the variable voltage source from 10 Ohms to 15 Ohms.

Resistor values that are used to simulate lines with error less than ±0.1 Ohms - 0.6 Ohms; 1.6 Ohm; 5 Ohm, 15 Ohm; 16,2 Ohm, 25 Ohm.

The EMF of each battery PP-63 - from 1.2 V to 1.65 V.

Capacity of each battery potentiometer - at least 9 Ah.

Voltage external battery from 1.2 V to 1.65 V.

The voltage of external battery to power the IRN - no more than 8 V.

The insulation resistance between the electrical circuits of the potentiometer and the housing in the operating temperature range and humidity no more than 80% at a voltage of 100 V of not less than 500 megohms.

Insulation between insulated electrical circuits of DC potentiometer PP-63 and the housing at a voltage of 250 V and frequency 50 Hz lasts withstand - 1 min.

Characteristics of the galvanometer М2032/1.

Constant current - less than 4.5 × 10-7 A/div.

Internal resistance - not more than 19 Ohms.

External resistance is not more than 250 Ohms.
