Hygrometer Barguzin-2

Also this device can be called: Barguzin2, Barguzin 2.

 

Barguzin-2 hygrometer culonmetric stationary for measuring the volume fraction of water at normal pressure in gases: air, nitrogen, oxygen, hydrogen, helium, and neon.

Device is splashdustprotected, showing, registration.

 

Scope: enterprises of the military-industrial complex, the starting ground space complexes, as well as nuclear and other industries.

 

Specifications Barguzin-2:

 

Measuring range of the volume fraction of moisture in gases - from 0.2 mln-1 to 1000 mln-1.

Dew point - from -85° C to -20° C under a pressure of 101.3 kPa.

 

Hygrometer has a measuring range of the volume fraction of moisture in gases:

- 0-2 mln-1 (from - 90° C to -70° C) with a unit price of the smallest category reading device 0,01 mln-1;

- 2-10 mln-1 (from -70° C to -60° C) with a unit price of the smallest category reading device 0,01 mln-1;

- 10-100 mln-1 (from -60° C to -40° C) with a unit price of the smallest category reading device 0,1 mln-1;

- 100-1000 mln-1 (-40° C to -20° C) with a unit price of the smallest category reading device 1 mln-1.

Unit price of the smallest category indicating device for dew points - 0,1° C.

Setting time hygrometer Barguzin-2 for each band, respectively - 60 min; 30 min; 15 min; 7.5 min.

 

Basic reduced (to the highest value of the measuring range) accuracy:

- by measuring ranges 0-2 mln-1 and 2-10 mln-1 - no more than ±10%;

- for measuring ranges of 10-100 mln-1 and 100-1000 mln-1  - less than ±4%.

 

Parameters analyzed environment hygrometer Barguzin-2:

- temperature - from -50° C to +60° C;

- pressure - from 0.03 MPa to 40 MPa (0.3 kgf/cm2 to 400 kgf/cm2).

Nominal gas flow through the analyte sensing element (at an ambient temperature of +20° C and atmospheric pressure of 101,3 kPa) - (100±1,6) cm3/min.

 

Sample gas flow through the bypass:

- when measured - not more than 3000 cm3/min;

- under a stream of air, nitrogen, neon and oxygen - not more than 10,000 cm3/min;

- purging with hydrogen - is not more than 5000 cm3/min;

- purging with helium - not more than 15 000 cm3/min.

 

Acceleration amplitude sinusoidal vibration in the frequency range from 5 Hz to 2000 Hz for 120 cycles with a cycle time of 20 s - 29 m/s2.

 

Output signal for data communication with other products:

- DC 0+10 mV;

- at the same time the DC voltage 0+10 mV and DC 0+5 mA.

 

Ripple of the output signal:

- at ranges 0-2 mln-1, 2-10 mln-1 - less than ±2,0%;

- at ranges 10-100 mln-1, 100-1000 mln-1 - less than ±0,8%.

 

Reliabilities hygrometers use under operating conditions for 2000 hours - not less than 0.9.

Up time depending on the measuring range:

- 0-2 mln-1, 2-10 mln-1 - less than 2 hours;

- 10-100 mln-1, 100-1000 mln-1 - 0.5 hour.

 

Time of continuous operation, during which the main measurement error does not exceed ±5% at ranges 0-2 mln-1, 2-10 mln-1 and ±2% at the ranges 10-100 mln-1, 100-1000 mln-1 - 7 days.

Deviation of the sample gas inlet pressure of the nominal - less than ±6%.

MTBF - 10,000 hours.

Average life - not less than 11 years.

 

Dimensions - 420×270×300 mm.

Weight Barguzin-2 - not more than 18 kg.

 

Hygrometers have a monitoring system complete extraction of moisture from the sample gas.
