Micro oval gear flow sensor-SN55A

Product introduction

The SN55A Micro Gear Flow Sensor has a built-in double elliptical gear, which is driven by liquid flowing into the measuring chamber of the Gear Flow Meter, with each tooth and the wall of the measuring chamber forming a space containing an equal volume of liquid. The volume of liquid flowing through is measured by the number of gears that a particular sensor detects passing through.
The SN55A gear flow meter is not affected by the viscosity of the medium, and has high measurement accuracy and repeatability, even at the upper and lower limits of the range. Especially suitable for measuring high viscosity media.
-Dual analogue switching outputs
-PNP/NPN selectable at will
-Highly accurate monitoring
-Precise dosing
-Wide range of media applications
-Not affected by medium pulsation
-Stainless steel/aluminium enclosure optionally available
-Digital signal control transmission
