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

Practice-oriented

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.
