Access to the measurement is facilitated with the inclinable probe lever, also allowing measurement in two directions. This model is also often used for aligning elements of a machine or a XY table, during installation. Highlights of the probe GT 31: • Automatic reversal of measuring direction • lever's laterally adjustable measuring direction on 180 ° • Coupled with the TESATRONIC TT10 display, the whole set becomes a ultraportable solution.
Typical qualities of TESA inductive probe: excellent repeatability, durability and longevity. All TESA electronic probes are mounted on ball bearings, except for miniature axial probes. The ball bearing guidance system is highly insensitive to radial forces exerted on the measuring rod. An anti-rotation device ensures a perfect movement of the mechanical guiding system. Measuring inserts can be replaced or exchanged. A wide choice of geometrical shapes and sizes are available. The measuring force can be adjusted by changing the spring, depending on the probe model.

TESA Axial Probes Standard Probes Universal probes for common but constraining applications. • 8 mm diameter probe housing. Can be clamped over its entire length. • Measuring bolt mounted on a ball bearing. • Both the probe housing and ball-bearing guide are separate from one another, so that the measuring bolt moves easily even if the probe is not clamped appropriately. • Degree of protection IP65 according to IEC 60529. • Wide range of accessories including measuring inserts, spring sets, etc. • LVDT probes compatible with measuring equipment from other makers available on request.
Miniature inductive TESA probes are particularly suitable for applications where space around the part to be measured must be the lowest. As an example application, inductive sensors can be mounted on a measuring head for checking bores or when domestic measures. GT41 and 42 provide excellent repeatability of 0.01 for a measuring range of ± 0.3 mm.
