Product Description:
Overview?
The HPQ-T sensor is designed specifically for liquid level detection by non-contact methods in clear or very translucent pipes. The sensor is mounted on a pipe that is between 3 to 7mm or 8 to 13mm in diameter and features an infrared light beam that becomes refracted and undetectable by the receiver when the liquid is present. The device runs on 10-28 VDC, has a response time of 2 msec max, has Light Operate/ Dark Operate Selectable output functioning, and has a 100 mA NPN or PNP output. There is minimal malfunction when air bubbles or water droplets are present. The indicator light is easy to view even when the sensors are gang mounted as all the controls and adjustments are located on the back side.
Benefits?Small compact size and non-invasive sensing make installation and height adjustment easyMany products to select from - provides flexibility to user based on concernsThru scan principle where liquid refracts light beam - insures reliable detection Infrared beam can help penetrate slurries and other solids with similar detection effect as water/liquid. This can be used in mixing sections of the process. Light operate / dark operate selector switch provides output flexibility. Indicator lamp is easy to view even when sensors are gang mounted
