Description
Applications
Pressure vessels or chemical tanks such as hydraulic acid or sulfuric acid.
Features
Insensitive to process conditions such as pressure, temperature and specific gravity.
Various wetted parts material to choose from for specific application
Versatile and easy-to-use controller. (MP2000)
Analogue output (2 wire, 4 to 20mA DC) available as standard.
Principle of Operation
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 a constant current is applied to terminals 1 and 2 in Fig.2, a voltage proportional to the combined resistance is gained on these terminals.
