Description
The signaling device of LELEKA gas is intended for continuous control to explosive concentration of natural gas in air of the installed gas rooms which are not belonging to the category explosive, it: apartments, houses, office rooms, schools and so on
At achievement of concentration operation threshold methane, the electric circuit of a signaling device of LELEKA gas realizes the following functions:
gives light and sound signals
provides switching of external electric chains of alternating current to 6 A with tension of 250 V
operates the 220 W pulse electrovalve, an alternating voltage of 220 V
Signaling devices of gas are issued two types:
on CH4;
the combined CH4 – WITH.
Main technical characteristics of a signaling device of gas of Lelek:
Nominal values of a threshold of operation of 15% of NKPR *
Absolute error at a temperature (20 ± 5) °C of ±7% of NKPR *
Absolute error in all range of temperatures of (-10 +15) % of NKPR *
