Purpose of the development: The gauge-switch of the fuel gas model "202" is a stationary electronic device of continuous action, which is designed to detect leakage of fuel gases (natural gas, biogas, propane-butane) and alarm system for warning and alarm when the gas concentrations specified level.

Recommended application field: Utilities.

Technical characteristic: Alarm enable pulse, the green LED Alarm indication: intermittent light, the red LED intermittent sound, piezo relay contacts open Power switching contacts, no more than 12 watts Delay relay 25 + / - 2 Operational temperature range from -10 to 40 ° C Air humidity 30 to 90% Dimensions with rosette diameter 120 mm, height 66 mm Weight with a rosette of not more than 230 g

Advantages over analogues: Substantial reduction in the risks of explosions from the beginnings of the flue gases. Price device 20 - 25% lower than the price analogs.

The development stage readiness: Ready for application

Description of the development:
()
The gauge-switch of the fuel gas model "202" is set in the residential and public buildings in accordance to "Technical requirements and regulations on the use of sensors explosive concentrations of fuel gases and trace carbon monoxide in the indoor air of residential houses, public buildings and structures", approved by the State Committee of Ukraine for urban planning and architecture. Early warning gives you the opportunity to take the necessary measures for the evacuation, leak, eliminate the cause of the leak. The gauge-switch is operated as part of the signaling systems in operation around the clock enable for a lifetime (at least 5 years). It has a separate power supply and signal loop. An alarm is generated by opening the relay contacts and duplicated inclusion own intermittent warning light and an audible signal. opening signal loop also occurs when supply voltage is interrupted or there is a fault. The connection is made using a standard four-contact sockets for fire detectors type DIP-3. Gas-sensitive element of the sensor-alarm is the semiconductor sensor is calibrated for methane concentration corresponding to 20% of the lower explosion limit under normal conditions. The electronic circuit consists of a thermo-compensated set point level, comparison circuits and signaling. The device provides protection against false positives, economic ON indication, the indication of a failure of the sensor, a simple control mode operation without activating the signal loop.
