Applications
Pressure vessels or chemical tanks such as hydraulic acid or sulfuric acid.
Features
Principle of Operation
Fig. 1: Operation of float and reed switches Fig. 2: Circuit in the stem
LR is comprised of a float and a stem. The float has a magnet inside. The stem incorporates a circuit board with reed switches and resistors placed at regular intervals.
For a rising level, float location and reed switches in operation change as shown in Fig.1, from A(2 switches in operation) to B (3 switches in operation), and then to C (2 switches in operation). For a falling level, from C to B, then to A.
This means that the combined resistance changes as the float rises or falls. When constant current is applied to terminals 1 and 2 in Fig.2, a voltage proportional to the combined resistance is gained on these terminals.

Level Measurement - OMEGA Engineering Like ultrasonic
sensors, capacitance sensors can handle point or continuous level
measurement. They use a probe to monitor liquid level changes in the tank,
electronically conditioning the output to capacitive and resistive values,
which are converted to analog signals. The probe and the vessel wall equate to
two plates of ... Level measurement 9AEI306.77 28 Principle of Resistive type Level Indicator
• The float acts as a primary transducer that converts liquid level variation
into a suitable displacement • This displacement is sensed by the secondary
transducer such as a resistive potentiometric device • The resistivepotentiometer
converts ... Level sensor – Wikipedia Loncat ke Resistive chain - These
sensors work well for liquid level measurements in marine,
chemical processing, pharmaceuticals, food processing, waste treatment, and
other applications. With the proper choice of two floats, resistive chain
