Maeda Koki MKCM Water, Oil, Air Signal Indicator

 

Feature

1. This product is the electric contact type flow sight by the combination of a reed switch and a magnet.
2. The reed switch enclosed with the transparent tube runs by the magnetic action of the magnet inside afloat. This product is the flow switch which is very compact and is easy to use.
3. Since the spring is being used for this product in a transparent tube, the postures when attaching are freedom, such as facing up, facing down, and sideways.
4. Since the transparent tube made of acrylic resin is used, the movement of a float or the flow condition of a fluid can be confirmed from the outside. However, the confirmation of a flow rate cannot be performed.
5. Since the reed switch is being fixed, adjustment of the operating flow rate value cannot be performed. However, the adjustment of some operating flow rate value is possible by exchanging the spring.

Standard specification

1. Maximum working voltage ＤＣ，ＡＣ ３００Ｖ
2. Maximum working current ＤＣ，ＡＣ ０.５Ａ
3. Contact capacity ５０ＶＡ
4. System of a contact ON type (Contacts are closed when fluid does not flow), or
OFF type (Contacts are open when fluid does not flow)
5. Acceptable Fluid Fluids, such as water, oil, and air
6. Standard pressure-proof １MPa (１０kgf／㎠ )
7. Working temperature range ０℃～＋６０℃
8. The connection system of a joint The female screw Rc(PT) is being used for a standard
product. However, the male screw or the combination of
mill size copper pipe and precision steel pipes are also
made.
