HBK U93A Force Sensor
U93A Miniature Load Cell
The small, robust and very stiff U93A reliably measures both static and highly dynamic tensile and compressive forces. Its small dimensions and good dynamic properties make it a cost-effective alternative to piezoelectric force sensors.
The mechanical connection is straightforward and secure thanks to the U93A's flange screw connections on both sides.
The sensor has an IP68 protection rating, making it suitable for outdoor use as well.
- HBK accuracy class: 0.2
- Nominal forces: 1 kN ... 50 kN
- Outputs: mV/V (passive), 0 ... 10 V, 4 ... 20 mA or IO-Link
Your advantages:
- Improved reliability: The Sensor Health monitoring of the U93A sends warnings in case of exceeding temperature or mechanical limits before problems occur.
- More information: Statistical information such as mean value or number of samples.
- Lower costs, easy setup: The U93A with the VAIO option come 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.
- Greater precision: Use your calibration and improve the linearity of your U93A.
Like all force transducers from HBK, the U93A is easy to configure, allowing it to easily adapt to various conditions. Its design, featuring supporting diaphragms, makes the sensor exceptionally robust and resistant to lateral forces.
Another useful feature for production environments is that the cable of the U93A force sensor is compatible with drag chains and is oil-resistant.
Benefits of all U93A:
Small, dynamic and robust
- Small diameter and flat design.
- Welded design from stainless steel, EMC-tested.
- High stiffness and small masses, leading to high fundamental frequency.
- Highly flexible cable, suitable for drag chains, resistance against most oils.
Besides being compact, the sensor is robust, EMC-tested, and delivers reliable results. It is ideal for measuring fast processes.
Immediately ready for use
- Various practical cable lengths, cable is suitable for drag chains and fuel-resistant.
- If chosen without in-line amplifier: TEDS available with a mounted plug for all HBK measuring amplifiers on request.
Time-saving plug-and-play sensors ideally suited for industrial environments.
