Detailed Description
ZP-12C Mine sprinkler dust device with a touch sensor
ZP - 12c mine sprinkler dust device with a touch sensor (hereinafter referred to as sensor) is our factory technical personnel after extensive research and trial and error, elaborate design and development of new products. The product and the factory production of ZP - 127 - z automatic sprinkler dust device for mine host, to prevent and reduce the mine dust has a very high applicability and good dedusting effect. The sensor probe using imported components, and at the same time equipped with sensitivity adjustment, time delay, the dust in coal mine is the preferred equipment.
Technical parameters:
1, the work input voltage: 127 v, the input current, ma, 310 or less: AC frequency 50 hz;
2, voltage range: 80% to 120% of the nominal value;
12 v / 3, the Ann output: 480 ma (rating);
4, the largest open circuit voltage 0:12. 5 v; The maximum short-circuit current I0:480 ma capacitor C0:16 uf; Inductance L0:0.2 mH.
5, the control signal input: switch signal;
Scope: 6, with solenoid valve pressure 0.2 MPa to 4.0 MPa;
7, adaptor sensor delay action time (1 ~ 45) s;
8, the maximum transmission distance sensor to the host: 200 m;
9, the protection way: double over voltage, over current protection;
10, works: continuous power supply.
Sensors in the coal mine working environment conditions
