S2'2012 FYP 2 -Week 7

For this week I have done research about sensor. I have done study for digital and analog sensor. After that I have conclude for chose the specification below. This is because for my prototype this sensor is very relevant to use and updated for industry.  

Magnetic Float Sensor                                                     

Function:Magnetic float switches / level sensor sare used to detect the
senor shave seale dreed switches in a stem with a permanent
magnet installed in the float.As float rises or falls, switch is
activated/deactivated.

Power House float sensor uses unique magnetic push at the                   
floating magnet to respond fast to any
change of liquid level.

Features:Unique magnetic lift
Suitable for water/oil or fuel sensing
Easy Installation
Can be installed directly on pipe

Switching Capacity             :10 W/VA
Switching Current               :0.5 Amp.max.
Switching Voltage              :25 V DC max.
Material                            :EngineeringPlastic                                   
Cable                               :2Core
