PRODUCT INTRODUCTION The Fine-tek Capacitance Switch for liquids and solids can be used in mediums such as liquids, pastes, syrups, powders, granules, flakes and chips. It’s broad application and rugged build makes it a highly versatile across all industries. As Capacitance Level Switch has no moving parts inside the device, it will not be affected by friction. It is suitable for powder or liquid application easy to install. The customer can choose the types for his requirements. Capacitance switches rely on electrical capacitance theory (the ability of a medium to store electrical energy)....

QUICK CALIBRATION DELAY FUNCTION CALIBRATION 1.Turn the "SENSITIVITY" to the "H" position. 2.Place a flat screw driver in the "Coarse" coarse hole, turn clockwise until INDICATOR turns on. Check whether "Indicator" light is on or not by turning the "Sensitivity Adj" knob again. 3.If not, repeat procedure. The default setting is 0 second when material comes into contact with the probe (Indicator ON) For setting the delay function, turn the screw clockwise. The further clockwise, the longer the delay. The delay function is suitable for mediums with agitators, splashing or level turbulence in...

INSTALLATION NOTICE The insulation part should be mounted to protrude 30mm from the vessel wall. SA160 should be mounted as above. To prevent false readings,check the flow pattern ( angle a) of the material and place the probe in the appro-priate location. If the probe is mounted on the top, make sure the length of probe long enough to touch the highest level of medium. The SA160 MODEL is usually installed at the lower wall of the tank. For Non-Stationary or vibrating environment, a separate control unit such as the SA140 is suggested. It is suggested to install the probe away from the...

INSTALLATION NOTICE The probe should not be mounted underneath a liquid inlet, otherwise it will switch on erroneously. If two parallel probes are mounted, they must be installed separately at least 300 mm to minimize interference . If the tank equips with agitator, please use the time-delay type to prevent fault level detection. Mounting the probe at a 20B incline will optimize the results and increase sensitivity. It also won't be damaged by the inflowing material. Mounting the probe at top of tank can avoid material bridges from forming. It's helpful to record accurate measurements. The...
