QT114数据手册传感器变送器的浮子液位传感器规格书PDF

描述 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
