Minidee Tank Gauge Switch
The Minidee Gauge Switch provides a single, compact solution for applications that require tank contents measurement, level alarms and pump or solenoid valve control. The standard version of the Minidee may be fitted with up to 4 micro switches that are actuated by cams fitted to the same shaft that drives the dial pointer. The switches can be supplied with normally open, closed or changeover contacts.
The 50 mm local dial may be calibrated in fractions, percentage, litres, or any other standard engineering units. It may also be scaled in 0C for transformer oil tanks.
Operation
As the liquid level in the tank changes the float arm moves vertically through an arc. This displacement is transferred via gears to a rotational movement. A magnet located in a pocket behind the gauge mounting flange drives a second magnet located inside the gauge body which turns the cam shaft and pointer. This mechanism ensures no fluid leakage into the gauge and allows adjustment or maintenance to be carried out without the need to drain the tank. End of travel float arm stops are fitted to ensure that the float does not come into contact with the inside of the tank.
