SMARTsaa developed Capacitance type continuous level transmitter for measuring levels of diesel and electrically non conducting liquids. The same can be used to monitor level of fuel tank of vehicles like buses, tractors, heavy machines and in DG tanks of mobile tower stations.  

OPERATING PRINCIPLE:

The probe forms an electrical capacitor with the surrounding metal contained wall, or with auxiliary reference probe. With the vessel empty, initial capacitances exists between the electrode and the metal well or the auxiliary reference probe. When the probe become covered with material to be measured the capacitances will increase and the change will be measured and covered into an analogue (4-20 mA) output signal proportional to the change. Rod or flexible cable can be used for various conductive or non conductive Liquids

 FEATURES:

• Compact, Low cost
• Analogue 4-20 mA, loop powered / 0-5 V O/P
• Rugged probe design

 SPECIFICATIONS:

Supply                :  24 V DC,
