Selection guide: GT 44 DC miniature DC probe ± 1 mm TESA
TESA GT44 DC probe, miniature, ± 1 mm, force = 0.4 N, radial cable – measuring range ± 1 mm; repeatability limit 0.1 µm; hysteresis 0.75 µm.
TESA inductive probes (half-bridge system) are selected according to measuring range (± 1, ± 2, ± 5 mm), measuring force (from 0.16 to 4 N depending on the material and finish of the workpiece), cable exit (axial or radial, depending on the space available in the fixture) and plunger lift (manual or pneumatic, GTx2 and GTLx2 versions). The GTL versions are linearised for maximum accuracy over the whole range; the DC versions have a voltage analogue output for PLCs; the USB versions connect directly to a PC without a display unit; the FMS parallel-guided probes are for measurements with constant force and interchangeable probes; lever probes are for hard-to-reach points. The probe must be paired with a display unit (TWIN, TT100) or an interface (M4P-3, TESA-MODUL) and with suitable contact points.
If in doubt, contact us: our technical support will advise you on the right model, measuring force, contact points and display unit for your application.
Integration and programming
The probe is fixed by its Ø 8 mm h6 shank in the holder or measuring fixture and connected to the display unit or interface via the 5-pin DIN connector (or USB for the USB versions, voltage output for the DC versions). Zeroing, presets, tolerances and formulas between several probes are set on the display unit; with M4P-3 and TESA-MODUL the signals go to PLCs, acquisition boards and SPC software. Probes with pneumatic plunger lift require the pneumatic accessories (electropneumatic pump, fittings) listed among the accessories.
Calibration and repair
Every TESA probe is supplied with an inspection report and a declaration of conformity. Periodic verification on gauge blocks or setting standards is recommended and, for quality systems, calibration with a traceable certificate; replace worn contact points and damaged bellows. After impacts or unstable readings the probe should be sent in for service.
Service: RODER S.r.l. – INNOVACHECK division handles verification, calibration with certificate and repairs of TESA probes and display units in Italy. Contact us stating the model and serial number.
