The sensor head of SANTEST's GYPM probe is more compact. By new design of probe head, screw side dead zone has been shortened to 30mm (Standard). As to tip dead zone, making short to 40mm is possible by option (standard: 70mm). Cable out direction is radial. GYPM probe is used in combination with the GYPMC controller, which provides analog output, 0-10V or 4-20mA, and can also be used in combination with GYHC or GYDC-05 controller, which provides velocity output or digital output.
