U2B Force Sensor: Reliable Tensile and Compressive Force Measurement

The U2B force sensor, tried and tested over a long time, is a diaphragm sensor – a design that is very well-suited for fast measurements. The sensor has a bending moment compensation to ensure that you get reliable results even if bending or lateral forces occur in the application. As a strain gauge sensor, the U2B measures both static and dynamic forces.

HBK has re-engineered the U2B series sensors for tensile and 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, while external dimensions remain unchanged.

HBK accuracy class: up to 0.1 (0.5 kN: 0.2)
Capacities: 0.5 kN to 200 kN
Output: mV/V (passive, Wheatstone bridge), 0...10 V, 4...20 mA or IO-Link

New: With the new option "VAIO", the U2B comes along with an integrated digital amplifier. Your advantages:

Greater precision: Linearity error 0.03 %, TC₀: 0.03 % / 10 K.
Improved reliability: The Sensor Health monitoring of the U2B sends warnings in case of exceeding temperature or mechanical limits before problems occur.
More information: Temperature measurement, statistical information.
Lower costs, easy setup: The U2B with the VAIO option comes along as adjusted sensor. When connected to an IO-Link master, you will get immediately precise readings in Newton. Low cabling costs.
Standard instrument features: Limit switches, peak detection, digital output, filter.
Fast: Internal sampling rate: 40 kHz, 0.9 ms cycling time to the IO-Link master.

Please have a look at the K-U2B- model. Beside many other options, you can find order information for the IO-Link version as well.

Advantages of all U2B:

Practice-oriented

High degree of protection (IP67) and stainless steel design.
Shock and EMC tested in compliance with international standards.
The versions with and without electronics have the same compact dimensions.

Benefit from the U2B’s maturity and long-life technology.

Adaptable and cost-effective

Configurable with plugs, TEDS and different cable lengths.
Available with an integrated amplifier; in this case, calibrated as a measurement chain.
New: Digital output (IO-LINK) with improved accuracy and sensor health monitoring.
Durable quality, proven design.

Save on cost: Sensor configuration at HBK, plug and measure at the point of use! Benefit from the advantages of HBK's IO-Link technology: Improved accuracy, less costs, even better relaibility.

Small displacement, excellent dynamics

Little deformation under load.
High stiffness ensures excellent dynamic behaviour.
Fast sensor for fast processes – also with integrated electronics, but measures also static forces.

Solve both static and dynamic measurement tasks using the U2B.
