PowerProbe (PP40 Series)
Linear & Rotary Motion
High-performance magnetically-coupled combined linear/rotary devices, designed for sample transfer. Both linear and rotary motion of the sample achieved via a single actuator with stroke length from 304mm to 1524mm.
The PowerProbe provides both linear and rotary motion of the sample, via a single actuator and is bakeable to 250°C without removing any components.
For demanding UHV applications, we recommend choosing the "XPP" option with rolling metal & ceramic bearings for smooth, low friction actuation, with minimal outgassing.
Features
- Unrivalled axial coupling strength
- 10x thrust and 4x torque compared to conventional devices
- Exceptional axial stiffness
- Zero backlash under low load
- Bakeable to 250°C without removing any components
The PowerProbe's powerful magnetic coupling technology provides performance far in advance of conventional probes on the market avoiding magnetic hysteresis and de-coupling issues suffered by traditional designs. The high torque characteristics are achieved by utilizing MagiDrive rotary coupling technology.
Combined with a high thrust linear coupling, this ensures optimum drive performance on both axes. Therefore, actuation of the thimble in either axis will result in the precise transmission of this motion to the sample. The PowerProbe can be fitted with a bakeable limit switch for the retracted position, aiding system interlocks.
A retracted switch option is available which provides indication when the probe is fully retracted. This signal can be interlocked to prevent, for example, the premature closing of a gate valve before the PowerProbe has fully retracted.

Specifications Table
| Model/Series | Linear and Rotary PowerProbe (PP40) |
| Mounting Flange Size | DN40 (2.75" OD) or DN63 (4.5" OD) CF Flange |
| Break-away Linear Force | 140 N (31.5 lbs) |
| Maximum Cantilevered Load | 20 Nm (177 in-lbs) |
| Available Stroke Range | 304mm (12") to 1524mm (60") as standard |
| Sample Weight/Load Capacity | Maximum recommended internal load carrying capacity will be a function of probe extension, but we recommend not exceeding a moment of 20 Nm (15 lbf ft). See Technical Data for deflection versus load graph. |
| Maximum Recommended Internally Applied Load When Vertically Installed | This is a function of the load acceleration. In a static case the load may approach the coupling break-away force; however, it would be wise to apply a sensible safety factor |
| Bakeout | 250°C (motor removed) |
| Pressure Range | Atm to 5 x 10-11 mbar |
| Position Locking | Thumbscrew (manual only) |
| Retracted Switch Option | Manually actuated drives may be purchased with an added "retracted micro-switch" to digitally indicate when the unit is in the fully retracted position. When used in conjunction with a PLC or other type relay, this can aid in ensuring a gatevalve is not accidentally closed when the probe is in the inserted position. |
