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.
The Digital Probe is one of an extensive range of Orbit Modules available for use with the Orbit
Measurement System, which provides an easy way to construct and maintain a complete measurement
system of up to 372 Orbit modules.
The Orbit protocol features an extensive set of commands that enable fast and efficient transmission of
data between the Orbit module and the PC.
Digital Probe Specifications
This section contains the specifications of the Digital Probe. There are two sections, the first are the
specifications for the complete Digital Probe (PIE + gauge head) and the second is mechanical data
relevant to the gauge head only.
PIE is designed to be primarily used with the T-CON connector. Full details of mounting with T-CON refer
to the section of PIE and T-CON installation.
