The 8020 sensor is designed for measuring the flow of neutral or slightly aggressive solid
free liquids.
The sensor is made up of a transducer and a measuring finger with a paddle-wheel which
paddles contain magnets.
The sensor detects the rotation of the paddle-wheel and generates a signal which fre-
quency f is proportional to the flow rate Q. The proportionality factor is called K factor; its
value is specific to each fitting and can be read out from the fitting instruction manual.
Following versions of the transducer are available:
- either with two pulse outputs (Hall effect sensor with 2 transistor outputs,
NPN and PNP),
- either with one pulse output (Low Power Hall effect sensor with 1 NPN transistor
output),
- either with one sinus output (coil output)
The electric connection is carried out via a cable plug EN 175301-803.
