APT3200 adopts high stability piezoresistive sensor, with a wide measuring range, good stability, strong reliability, excellent anti-interference ability characteristics. APT3200 is completely sealed for submersion, yet vented through the cable to correct for barometric pressure changes, The conductors of the cable are also isolated from the outside environment to keep the sensor operational for long-term use. It can provide a cost effective solution for level monitoring for a variety of application.
