MKCM type AIR SIGNAL

[ Flow rate with a switch ]
　 to detect the flow of fluid, it is turned ON or OFF the switch at your specified flow rate
　 ※ switch is fixed (can not be set value changes later) [ flow is visible at a glance ] transparent tube of a galvanometer to check the flow of fluid in the movement of the float [ with protective cover ] by the metal protective cover the possibility of damage due to impact or the like from the outside 　 and reduce. [Mounting orientation does not matter ]　attitude of when mounting because it uses a spring inside is 　you can do up and down and sideways, etc. freely.

Caution on the flow switch use
1. Notes on the magnetic impact
　● reed switch, since the switch acting on a magnetic, used where not affected by the magnetic field, please.
　● When the magnetic material of iron such as in the vicinity of the reed switch is present, it becomes the cause of the malfunction.
2. Notes on the electrical connection
　● flow switch, it is an over-current flows through the reed switch in the cause, such as a ground wire connection failure as no
　　Please note the connection.
　● Please use as much as possible the alarm detector flow switch.
　　In conjunction with other electrical equipment if you want to use and is, on the sufficient consideration of the influence of when the malfunction occurs, please handling.
　● use voltage, when used in suppressing the current used is as small as possible, the life of the reed switch is long Masu no longer.
　　(Usually 100V0.5A about under the circumstances 100Million times switch actuation can be used)
