Design And Measuring Principle - Burkert 8020 Manuel D'instructions

1. DESIgN AND mEASURINg PRINCIPLE

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.
