Capacitive sensor promises accurate level detection
Carlo Gavazzi has launched its latest CD34CNFLF capacitive sensor with foreground suppression, designed to detect water-based liquids through a non-metallic container wall.
The CD34 automatically adjusts to various thicknesses of plastic and glass; detecting while ignoring residue film, moisture or foam from liquids such as water, milk, acid or alkaline solutions with high conductivity inside or outside the container wall.
The CD34 has an IP69K rated housing and has UL and ECOLAB approval for wash-down applications. It includes NPN and PNP versions and has a rated operating voltage of 10-30VDC (incl. 10% ripple), voltage drop of <1.5 VDC at a maximum load, and an output current of 100mA. It also includes short circuit reverse polarity and transient protection. Each unit is supplied with either a 2m cable or M8 4 pin pigtail connector.
A universal mounting brackets allow for multiple mounting methods to suit various tubes and containers that may be used in a wide range of industry applications.
