Senso 3000 Hydraulic Tool Holder Force Gauge

The SENSO 3000 is a specialized tool for verifying correct operation of hydraulic tool holders. For workholding collet force gauges, please see our ForceCheck collet force gauges.

SENSO 3000 determines the clamping force of the hydraulic chuck via a pressure sensitive plug gauge. The entire length of the plug gauge is clamped in the hydraulic chuck so that when tightening the clamping screw the clamping pressure of the chuck is optimally applied. The clamping force measuring instrument displays the clamping force as an absolute measurement value on the one hand and as a percentage clamping force in relation to a reference value that can be set individually on the other. This way, SENSO 3000 can be adapted to customer specific application conditions and requirements.

The clamping force measuring instrument is supplied with a plug gauge for the respective clamping diameter as well as a carbide proofing bar for calibration purposes and a CR 2430 type battery – all in a sturdy and handy case.

Workholding Collet Drawbar Force Gauge

ForceCheck collet force gauges measure the drawbar pullback force of a 5C, 16C, or 20C collet workholding system. Measurement of collet drawbar force provides an easy way to ensure correct force from machine to machine, or between setups for different parts.

Chuck Force Gauges - Wired

Designed to quickly check the holding force on a chuck or turning-center. The wired chuck force gauge can be customized for any diameter.

ForceCheck Workholding Collet Force Gauge

ForceCheck collet force gauges provide a quick and easy way to check force on collet workholding systems.

Applications for ForceCheck workholding collet force gauges include:

-Comparison of holding force between machines, allowing for consistent and repeatable production results regardless of mechanism (manual, hydraulic, or pneumatic)
-Periodic verification to assess if preventive maintenance is needed
-Establish correct holding force for running a particular part or job
-Determine optimal holding force for thin-wall, rings, and other parts sensitive to damage or distortion when machining


A sensor is needed for each diameter to be measured. A ForceCheck base set with display is needed to display results (order separately).
Sensors are also available in low-force versions. Contact us for further information.
