Foerster SONO probes and stands – UCI and Leeb probes for SONODUR instruments
Applications
For choosing the right probe for the task: from everyday manual measurements to thin coatings and automated inspection. UCI probes use the ultrasonic contact impedance method: a Vickers diamond on a vibrating rod is pressed in with a defined force, and the frequency shift is converted directly into hardness – no optical evaluation of the indentation is needed. UCI probes are compatible with SONODUR 3 and SONODUR R, Leeb probes with SONODUR 3 and SONODUR 3 LITE LEEB.
Models and accessories
| Probe / accessory | Purpose and features |
|---|---|
| SONO H – manual UCI probes | compact, stainless steel housing 25 × 177 mm; full Vickers scale range; metals, technical ceramics, with limitations – nodular cast iron; tip Ø 3.4 mm (optionally 1.7 mm) |
| SONO M – motorised UCI probes | automatic force application – operator-independent measurements; low forces for thin coatings and sensitive surfaces; anodised aluminium housing 38.5 × 188 mm |
| SONO S – guided UCI probes | integrated probe guide, interchangeable feet for flat surfaces, tubes, wire, round workpieces; housing 38.5 × 169 mm |
| SONO L – Bluetooth Leeb sensors | for large, massive components: min. weight 5 kg, wall >25 mm (SONO HLD); HV, HB, HRC, HRB, HS, tensile strength |
| Cabled Leeb D and G probes | powered by SONODUR 3 – no charging needed; ON/OFF switch saves the battery |
| SONO MS 1 (M), MS 2 (M), PS 1, PS 2 stands | guided measurement reduces operator influence; MS 1 with magnetic base (H probes up to 60 mm, M – up to 140 mm), PS 1 – for checking probe calibration and for small, thin parts |
| Hardness reference blocks | for checking and calibrating UCI probes and Leeb instruments; with factory certificate, on request with DAkkS certificate |
