DESCRIPTION -
The QT114 QLevel™ charge-transfer (“QT”) sensor IC is specifically designed to detect point level in fluids and powders. It will project a sense field through almost any dielectric, like glass, plastic, or ceramic, to sense level on the inside of a vessel, from its exterior. It has the unique capability of independently sensing two trip points when used with structured electrodes having two tiers.

● Limit sensing of almost any fluid or powder
● Two-tier level sensor - Hi / Low limits with one probe
● Only one external part required - a 5¢ capacitor
● Uses internal probes or external electrodes
● Active high or active low outputs
● Slosh filter averages response of moving fluids
● LED drive capable on both outputs
● 2.5 to 5V 20µA single supply operation
● HeartBeat™ health indicator on both outputs
● RoHS compliant package

♦ Medical fluid sensing
♦ Soil moisture sensing
♦ Consumer appliances
♦ Automotive fluids
