• UV-01/02 ultraviolet flame switch adopts cassette crust of installation. It installs the ultraviolet light sensing tube as the flame sensor. This makes it possess the merits, such as small bulk, convenient employment, reliable work, long service life and so on. It can be widely applied to various kinds of fuel gas, monitoring the flame of oil-fired boiler, flameout alarm and the location that need the flame monitoring.

1、Operating voltage: UV-01，24VDC；UV-02，220VAC； ± 10%
2、Input signal: the spike sent by the ultraviolet light sensing tube ultraviolet photosensitive cell flame sensor.
3、Output signal: a relay alarm normally open node （0.3A）,attracting when there is fire, and open when there is no fire.
4、Operating distance measurement:  the maximum length between the probe and the middle place of the quadric table is 8m; sensitivity of Operating distance measurement is a candela in 10m.

    UV-03  flame monitor

1、 UV-03 serial flame monitor adopts 89C52 serial SCM as control unit, completes the collection and management of signals and controls the output，and adopts the ultraviolet light sensing tube as the flame sensor. This makes it possess the merits, such as small bulk, convenient employment, reliable work, long service life and so on. It can be widely applied to various kinds of fuel gas, monitoring the flame of oil-fired boiler, flameout alarm and the location that need the flame monitoring.
2、Operating principle: when the flame probe is illuminated by the flame, the ultraviolet light spring the light sensitive tube and make it output pulse signal which is directly sent to controller. CPU analytical judge and process the signal after it input the circuit. The results of processing will be sent to output circuit and display circuit, and complete alarm output and display of flame intensity. The operating distance sensitivity of measurement is less than 15m.
