4 Gap Measurement When checking the gap between the workpiece and the nozzle as shown in the illustration, the output of the varies with the surface roughness of the workpiece or the dimensions of the nozzle. Nozzle length Nozzle diameter Workpiece Gap Air supply Examples with -1C (Typical) Influence of Surface Roughness of Workpieces Influence of Nozzle Diameter Influence of Nozzle Length 1.-S -S Conditions Nozzle dia.: mm Nozzle length: 1 mm Air pressure: 1 kpa Conditions Nozzle dia.: 1 mm Surface roughness of workpiece: 1.-S Air pressure: 1 kpa 1 dia. Conditions Nozzle dia.: 1 mm Surface roughness of workpiece: 1.-S Air pressure: 1 kpa mm dia. 1 mm -S dia. mm Gap (µm) The output varies with the surface roughness of the workpiece even though the gap is constant. The rougher the surface of the workpiece is, the more noticeable the variation of output is with a small gap. The variation rate versus gap change is not large in such cases Gap (µm) The larger the nozzle diameter is, the larger the variation rate of output versus gap change is Gap (µm) The smaller the nozzle length is, the larger the variation rate of output versus gap change is.

6 Safety Precautions WARNING This product is not designed or rated for ensuring safety of persons. Do not use it for such purposes. Precautions for Correct Use Do not use the product in atmospheres or environments that exceed product ratings. Mounting If the diaphragm is damaged, the Sensor will not operate properly. Do not insert a screwdriver or steel wire into the interior of the pressure-sensitive parts through the pressure port. The pressure inlet has an R (PT) 1/8 taper screw and M female screw that conforms to JIS Standards. Apply sealing tape around the female taper screw so that no pressure leakage will occur. The most-suitable wrench is 17 mm in size. Make sure that the tightening torque of the M female screw is 9.8 N m or less. Dimensions Adjustment After the pressure is set with the pressure adjuster, cover the adjuster with the rubber bushing so that no dust or any other foreign material will penetrate into the interior of the.
