Model FP5 Flat Plate Movement Sensor. The sensor’s active surface is 2.54cm in diameter and extremely sensitive. Like the H14-LIN, produces a TTL/CMOS compatible pulse for each particle impact. Like the H14-LIN, the FP5 is well suited for remote use in all environmental conditions including the extreme environment of Antarctica. It comes with 6 meters of stainless steel wrapped conduit shielded cable. There are three wires; +12V (red), ground (black), and a particle count output wire (green). It comes with 600µm and 1,000µm (diameter) glass spheres for testing. A detachable wind diffuser is also supplied to help prevent scouring around the sensor in the sand. It has a 1/4″-20TPI hole in the bottom for mounting. This will fit most camera tripods. A variety of stainless steel hardware is also supplied for attachment including a 1/4″ x 9″ shaft that screws into the base to penetrate the ground keeping the sensor upright and misc. bolts, threaded stock, etc.
