C2 Force Sensor: Reliable Compressive Force Measurement

The C2 force sensor, tried and tested over a long time, is a diaphragm sensor – a design that is very well-suited for fast measurements. This sensor, with integrated lateral force compensation, works safely even in the event of lateral forces or non-centric force application.

HBK has re-engineered the C2 series sensors for compressive force measurement to enable quick and optimized response to spare parts requirements and new designs. Different cable lengths, mounted plugs and TEDS are available, allowing for more efficient installation. In addition to the well-known passive versions of the force sensor, optional versions are now also available featuring integrated electronics and a current or voltage output (4 –20 mA or 0 – 10 V), while external dimensions remain unchanged. 

  • HBM accuracy class: Up to 0.1 (0.5 kN: 0.2)
  • Capacities: 0.5 kN to 200 kN


  • All variants are made of stainless steel and have a high degree of protection (IP67)
  • Shock and EMC tested in compliance with international standards
  • Compact dimensions


Benefit from the C2’s maturity and long-life technology.

Adaptable and cost-effective

  • Many configuration options: mounted plugs, TEDS and various cable lengths
  • Available with an integrated measuring amplifier; in this case, calibrated as a measuring chain
  • Identical dimensions with and without integrated electronics

Save on installation costs by adjusting the sensor in advance so that it fits your application! Now also available with an integrated measurement amplifier.

Small displacement, excellent dynamics

  • The C2 shows only little deformation under load
  • Its high stiffness ensures excellent dynamic behaviour
  • Fast sensor for fast processes – also available with integrated electronics

Solve both static and dynamic measurement tasks using the C2.

Now available as an option: C2 with integrated amplifier

It's your choice: you can now order the C2 with an integrated amplifier: VA1 with voltage output (0 –10 V) or VA2 with current output (4 – 20 mA). Neither the dynamics nor the metrological properties change!

The amplifier is matched to the sensor. This offers the following advantages:

Easy integrationSame electrical connection: All HBK force sensors come with an M12 plug, pinning is the same for all models.
FastWith a bandwidth of 2 kHz, the amplifiers are also ideally suited for fast processes.
ReliableThe active sensor meets the same stringent requirements for shock and vibration resistance as the version without an amplifier.
The amplifier is robust in all fields of application and is optimally suitable for industrial applications due to its IP67 degree of protection and the use of exclusively stainless materials. Versions with M12 connectors offer the same degree of protection.
CalibrationThe amplifier converts the force signal (N) into a current or voltage signal (mA or V). Calibration certificates, in compliance with DKD R3-3 or ISO376, are also available for the sensors with a measurement amplifier.
AccuracyBoth versions, with and without an integrated amplifier, have the same accuracy class.
