Introduction The Digital Probe is a gauging transducer combined with conditioning electronics in a permanently connected ”smart connector” or PIE (Probe Interface Electronics). The PIE converts and corrects the output from the gauge head and transmits the result in a digital format using the Orbit protocol. Because the Digital Probe is factory calibrated using a reference Laser, the probe has a very linear output with position.
Network type Network speed Network Control Character Command Character Format Orbit - RS485 2-wire multi-drop (up to 31 per channel) 1.5Mbaud, 187.5k Baud or 9600 Baud (do not use 9600 Baud for New Applications as this will be phased out) Break Character - low (space) of >90 us (187.5k Baud) or >1.2mS (9600 Baud) 1 start, 8 data, 1 odd parity, 1 stop bit Accuracy The error quoted assumes periodic re-setting against a setting master in accordance with normal gauging practice (not less than once per day).
Gauge Head Application Information When mounting the Gauge Head in a fixture, care must be taken as the linear bearing assembly at the tip end is made to very fine tolerances. If a high force is applied to the probe casing performance may be affected. Ideally probes should be clamped in a yoke, split or collar clamp. If single point screw clamping is adopted (see diagram), then a tightening torque (in Nm) should be limited to that which will give a maximum of 50Kg point load.
Cable The Gage Head cable is custom made to achieve the optimum balance between flexibility, flex life, chemical resistance, abrasion resistance electrical and electrical screening. To minimise transducer failure due to cable damage cable runs should be positioned well clear of moving components and vulnerable working areas.
