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 with 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
Output: mV/V (passive), 0...10 V or 4...20 mA

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 configure the sensor so that it fits to your application! Now also available with an integrated amplifier.

Small displacement, excellent dynamics

The C2 shows only little deflection under load
Its high stiffness ensures excellent dynamic behavior, excellent for fast measurements
Suitable for static measurements due to strain gauge technology

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 integration	Same electrical connection: All HBK force sensors come with an M12 plug, pinning is the same for all models.
Fast	With a bandwidth of 2 kHz, the amplifiers are also ideally suited for fast processes.
Reliable	The active sensor meets the same stringent requirements for shock and vibration resistance as the version without an amplifier.
Ambient conditions	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.
Calibration	The 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 amplifie
Accuracy	Both versions, with and without an integrated amplifier, have the same accuracy class.
