Sensit company (started in 1978), is the leader in erosion measurement sensors. Design of these sensors has been provided in part by the USDA-SBIR (Small Business through Innovative Research) program. We have been awarded three SBIR research grants for erosion sensor design and feasibility. All three research studies were successful.
Sensit company currently manufacturers two state-of-the-art, remote site erosion sensors as shown below. The model H11-LIN is vertically mounted above the surface of the ground and is used for mass flux and movement monitoring. The model FP5 is an extremely sensitive flat plate surface movement detector providing data the instant movement occurs. When this data is processed with wind speed data, very accurate values for threshold of movement (wind speed or stress, U*) throughout an erosion event is easily determined.
