Feature: 1. Accurate sensor: adopt semiconductor sensor, with high stability and low sensitivity drift. Supports sensor fault detection and intelligent microprocessor control. 2. Extensive use: widely used for automatic control of gas pipeline ball valve, gas cylinder ball valve, various connection alarms, other gas and liquid valves. 3. Good control: The switch allows the manipulator to switch automatically and electrically. In the event of a power outage and maintenance, the valve can be opened manually to double safety. 4. Automatic shut-off: The automatic shut-off valve is quick and reliable. When the alarm is triggered, the main valve at home is automatically closed and the power supply is completely cut off, which is very safe. An insulated sealed fireproof shell is adopted. Anti-radio interference. 5. Leak alarm: used in places where combustible gas may leak, such as liquid fossil petroleum gas, natural gas, biogas, etc. > Controller material: ABS, aluminum alloy. Controller Application: Widely used for automatic control of gas pipeline ball valve, gas cylinder ball valve, various connection alarms, other gas and liquid valves. Controller working pressure: 0.1 MPa Controller working temperature: -10~+50 Alarm material: ABS Alarm battery: 1 x 9V 6F22, without battery. Alarm socket: AC90~240V Alarm application: used in places where combustible gas may leak, such as liquid fossil petroleum gas, natural gas, biogas, etc. Alarm measuring range: 3000PPM 1500PPM.
