This heavy duty, stainless steel probe comes in a standard 8" length and is designed to be attached to the PROCAP I or PROCAP II capacitance probe. The solid 1" wide diameter probe provides increased surface area for maximum sensitivity and performance. It is suitable for use in temperatures up to 500°F (260°C), making it appropriate for challenging applications such as fly ash or clinker. It can be used for low or high level detection in heavy materials such as coal, aggregates, grains, or other materials with a high bulk density and features a PRO-Shield to guard against false readings from material buildup on the probe.
