Product Description
Sensor Transmitter
Gas Alarm Marketing supplies NC56 level sensor transmitter from FISCHER Germany. It is designed for level measurement of clean water, waste water and sewage, diesel fuel, fire suppression foam, tank monitoring, dry run monitoring for non-, aggressive media.
The NC56 applied to plastic or metal tanks, and configured for measuring level in ranges from 400 to 2000 mm.
Principles of Operation
Two parallel metal rods with a fixed distance between them form a capacitor when charged with an A.C. voltage. When these rods are immersed in a liquid medium, the capacitance value is a function of the immersed length. With the probes fixed vertically downward, the immersed length is proportional to the liquid level. The capacitance of the probes is therefore a function of the level. An electronic circuit module in NC56 Level Sensor converts the capacitance value to a level measurement and transmits as a linear standard electrical signal: 0-20 mA, 4-20 mA, 0-10 V DC, 0-5 V DC, 1-5 V DC or 2-10 V DC.
