Inside micrometer SBM-Deep-Hole

borefor hole diameterdigital display

Operated by a pneumatic actuator powered by a 3 bar compressed air supply - either from a compressor or a workshop air-line. The measurement data is collected by a capacitive probe fitted just behind, and in constant contact with the measuring head. This direct contact ensures high-quality transducer-type accuracy, even at great depths. Measurements are taken by pressing a footswitch connected to the airline and the data is then passed automatically via cable back down the bore to the digital readout at the operator end. Features • Measures diameters from 50-310mm, up to 15m deep • Spherical, Tungsten Carbide anvils • 2 point and 3 point heads available • Accuracy +/-0.005mm (subject to bore condition) • Quick set-up time • Easy to use • Not adversely effected by temperature fluctuation • Robust design • Various readouts available
