Electromagnetic Level indicators with a continuous signal Ohm or 4-20mA Accuracy 12 - 24 - 36mm made for oil or S/steel AISI 316 version

USE

The Levels electromagnetic reed-chain resistors Indicators allow a precise and constant indication of the fluid level, regardless of its electrical conductivity, pressure and temperature and by the presence of foam in it; essentially they have a simple structure, since the only moving part is the float which, depending on the flow or drain the liquid, flows through a tube.

OPERATION

The floating stay within a toroidal magnet, whose field operates, without physical contact, small reed contacts placed inside the pipe flow (see Fig.1). The drive of these contacts allows the integration or gradual shutdown of the resistance, also placed inside the pipe flow, allowing the continuous reading of liquid level. Resistive signal thus generated can be directly used by devices that accept inputs well structured, or through a converter Ohm - 4/20mA can drive most of the electronic devices on the market (PLC).

TECHNICAL ADVANTAGES

Constant and continuous indication of the level with high accuracy of repeatability. - Linear index of the level, regardless of the shape of the tank and the distance between gauge and the tank walls. - Remote indication of the measure and possibility of piloting of additional controls. Possible assembly by-pass.
