Safe piezo technology at high temperatures
PACEline CHW: Suitable for use in extreme environments but still just as easy to handle as any other piezo sensor:
Our PACEline CHW is deployed in force shunts. That means that the sensors have to be calibrated in their final mounting position. PACEline CHW – like all other piezo force sensors – was developed specifically for pre-stress applications. The PACEline CSP/100 kN unit by HBM generates pre-stress in temperatures up to 300°C.
- Safe piezo technology at temperatures as high as 300°C
- Permanently welded cable, safe and close to the sensor
- Proven quality by HBM – PACEline piezo technology
Force measurements at extremely high temperatures: Use cases
- Monitoring of rolling processes in metal production
- Production monitoring during pressing, hot gluing, etc.
- Experimental mechanical stress tests at high temperatures
- Test benches for extended temperature ranges
PACEline CHW: Available in 2 versions
CHW-2/60KN: Temperature range: -55°C … +200°C
- Piezoelectric force sensor, quartz sensor elements
- Fixed cable, welded to the sensor
- Your reliable force sensor for measurements in ambient temperatures up to 200°C
CHW-3/60KN: Temperature range: -55°C … + 300°C
- Piezoelectric force sensor, gallium-phosphate sensor elements
- Fixed custom high temperature cable welded to the sensor
- The reliable option for force measurements in temperatures up to 300°C

Mounting aid for Force washer
Piezoelectric force washers require pre-stressing. The new CPS sets of pre-stressing elements facilitate easy and permanent pre-stressing. They are made from stainless steel and offer the required hardness as well as the bolt pitches selected to match the typical pre-stressing force.
A set of pre-stressing elements includes a bolt, a washer and a nut. The figure below gives a schematic representation of the setup.
Accessories and Cables
Accessories
CSB4/1 summing box
Simplify the installation of piezoelectric sensors. The CSB4/1 summing box enables up to four piezoelectric sensors to be connected in parallel to an amplifier input. It can be fastened with screws and features electrical isolation of enclosure and sensor shielding.
