HP-THDe Touch Trigger Probe

The HP-THDe touch trigger probe has been designed to take advantage of cutting-edge technology and deliver highly accurate touch trigger probing with styli builds of up to 100 mm. It offers high-precision repeatability and low 3D form error thanks to a highly innovative opto-mechanical design capable of detecting nanometric movements in the X, Y and Z directions.

Guaranteed accuracy
Unlike standard probes which employ a mechanical switch to create probing points which leads to small form errors sometimes called ‘lobbing’ the mechanical design of the HP-THDe touch trigger probe overcomes this force and delivers very low lobbing in all six probing directions.

Maximised versatility
The HP-THDe is a modular probe. Modules can be changed rapidly without the need for calibration using the existing HR-P passive rack. The probe is also compatible with existing Hexagon extensions and styli.

Extended durability
The robust design of the HP-THDe protects it perfectly against contamination and collisions. Also, thanks to the optomechanical technology, the HP-THDe lasts for up to 10 million individual measurement points.

  • Features & benefits

    TargetExcellent repeatability and 3D performance with styli lengths up to 100 mm
    The HP-THDe touch trigger probe is recommended for applications with tight tolerance and those that require a high level of point density and high-speed measurement. It is also suited to applications that require long styli builds. 

    SensorAdaptive triggering
    Unlike other systems on the market, HP-THDe has an adaptive trigger than can be controlled by the measuring software and machine controller. The trigger parameters are automatically adjusted when loading a new stylus build, ensuring optimal measuring performance at all times.

    Real-TimeEnhanced productivity
    The HP-THDe benefits from a fast stylus change and increased module life compared to a typical touch trigger probe, therefore productivity is enhanced saving both time and cost.

    PickaxeRobustness
    The HP-THDe has been designed to be as robust as a standard touch trigger probe, reducing downtime and cost of ownership.
