AL707 SF6 Leakage monitoring and alarming system
Performance standards:
GB/T14598.10-1998, GB/T14598.14-1999, GB/T17626.5-1999.
Features:
1, the environment, SF6 gas detection. When SF6 gas concentrations over 1000ppm, display level exceeds the information.
2, SF6 gas content exceeded alarm.
3, the oxygen content in air detection. Display switch turns the gas sensor at the indoor oxygen concentration.
4, the oxygen alarm. When the oxygen concentration of less than 18%, the output alarm signal contacts and conduct on-site voice alarm.
5, excessive levels of oxygen or SF6, automatic exhaust function.
6, the alarm can be set.
7, the environment temperature and humidity detection display. System can measure and display the current switch to the indoor temperature and humidity.
8, regular exhaust function. Every time the system can be set to fan only time Kai.
9, Forced ventilation function. Fan is stopped, press the button to force mandatory ventilation 15 minutes.
10, the fan start and stop time display.
Product parameters:
1, Power supply: the host and sensor AC 85-265V 50HZ or DC 110-340V.
2, power consumption: Host <25VA sensor <5VA.
3, Alarm contact capacity: AC220V/7A normally open / normally closed.
4, fan contact capacity: AC220V/15A normally open.
5, sensor detection accuracy: oxygen concentration ± 1% FS SF6 <10% threshold.
6, the sensor measurement range: oxygen (1.0 ~ 25.0)% SF6 50ppm - 10000ppm.
7, sensor stability: oxygen, ± 0.5% FS.
8, the sensor repeatability: oxygen ± 0.5% FS.
9, the oxygen concentration alarm: 18.0%.
10, fans start concentration point: oxygen 19.6% SF6 1000ppm.
11, the fan manually start time: 15min.
12, communication interface: RS-485 bus baud rate: 4800bps.
13, the temperature display range: -55.0 - 125.0 ℃.
14, Humidity display range: 10-99% RH.
