Boiler alarm GS-500-K-CH4

Alarm checks for gas furnaces boilers, furnaces, and other gas consuming equipment, when included in automatic safety any type. It bans the ignition of the boiler with gas furnace. Working conditions macroclimatic areas with moderate and moderately cold climate.

Alarm is an indicator with a light signal and a fixed threshold of gas content.

The alarm device consists of two parts: electronic circuit with the actuating relay, located in polypropylene housing and selected device - diffusion method of supplying a controlled environment to gauge it placed in the flue.

 

TECHNICAL DATA

                                

Threshold signal concentration by the calibration component, induced by the led (1 % by volume shares (OD)), corresponds to the 20 % lower concentration limit of flame propagation (LEL). The threshold concentration may be determined according to the requirement of the customer. The verification component is methane.

When the prescribed concentration from 1% volume fraction (ML) and above, lights up the red led "ALARM" and triggers the Executive relay is included in the automatic safety of the boiler.

Operating conditions:

          - the range of controlled OD of methane from 5 to 50 % LEL;

          - the temperature in the place of sampling not more than 300 ° C

- ambient temperature the air in the area of location of the secondary device (5-45) ° C

- humidity in the working area, not more than 95%;

- atmospheric pressure 84-106.7 kPa

- the vacuum at the point of selection sample, 2-20 mm. V. senior (20 – 200 PA)

- the maintenance of mechanical and aggressive impurities should not exceed sanitary norms according to GOST 12.1005-88;

- dust content not more than 10 ±3 g/m3;

- flow rate controlled environment , no more than 0.5 m/s.

 The parameters of the controlled environment:

- the range of concentration of measured components 0-95% LEL;

the temperature of 5-35 ° C;

- relative humidity up to 98% at temperature of 25 º C;

- dust content not more than 10 ±3 g/m3;

         - the contents mechanical and corrosive contaminants not exceed health standards according to GOST 12.1005-88;

 Maximum permissible absolute error by the calibration component (D) in working conditions 10% LEL.

 Electrical power the alarm device is performed with a voltage of 220 V, 50 Hz.

 The method of delivery of a controlled environment sensor in – diffusion.

 Dimensions:

          - Signaler, mm: 120*58*40;

          - select device length 544*mm, diameter 40 mm.
