Planar Sensors come in a variety of sizes and configurations.  The two open frame sensors shown here are for low temperature applications (140ºF/60ºC and less) and are constructed of aluminum and virgin Teflon.  All aluminum parts are treated with hard, black anodizing or nickel plating.

A Five Element Planar Sensor is shown here.  The five element presents an increased field density and is generally used for applications of low density/weight, and or thin products.

The High Temperature Sensor shown above is made with nickel plated aluminum, high temperature ceramic blocks, and Teflon coated coax cables, is rated for temperatures up to 500°F (260ºC).  The electronics are normally remote mounted in a NEMA-4 enclosure ten feet from the sensor.

The Ultra-High Temperature sensor is made with stainless steel, high temperature ceramic blocks, and stainless steel cabling provide excellent durability and accurate moisture measurement for in-kiln temperatures up to 1000°F (500ºC).  This high temperature capability provides added longevity for in-kiln measurement as well as the ability to measure closer to the front entry of the kiln where temperatures may exceed 500ºF (260ºC).  The electronics are normally remote mounted in a NEMA-4 enclosure ten feet from the sensor.
