Configurable Tension and Compression Force Sensors

Calibrate these sensors to your desired capacity to measure tension, compression, or both. Also known as load cells, they measure and track the forces of your equipment by converting them into electrical signals. Send these signals to your computer or programmable logic controller (PLC) to monitor, document, and trigger actions in your machinery.

When choosing a sensor, consider whether you’ll be measuring tension, compression, or both. Select sensors with a capacity rating higher than the greatest load you expect them to receive. They’re designed to briefly handle forces 1.5 times their load capacity to protect from overload. Choose between a rectangle, round, or S-shape sensor to best suit your application.

For the most accurate measurements, calibrate these sensors to your data acquisition system or display.

Button	Threaded Through Hole

Threaded Standoff	Threaded Stud

Dual-Sided Threaded Stud

Round sensors have a low profile to fit in tight-clearance spaces.

Threaded Stud—Those with a threaded stud screw into equipment.

Threaded Through Hole—Those with a threaded through hole are also known as pancake load cells. They can be bolted to surfaces in any orientation and are commonly used to measure clamping forces. They can be mounted in any orientation.

Button—Those with a button are often used to measure weight in packaging machinery and for pressure sensing in medical device prototypes. Those without mounting holes are about as thin as a credit card. To mount, sandwich them between two plates or use a thin layer of adhesive. They can only be used for compression applications.

Dual-Sided Threaded Stud—Those with a dual-sided threaded stud can monitor push-pull forces. For example, they might be used to test the durability of products that repeatedly fold and unfold.

Threaded Standoff—Those with a threaded standoff have a threaded hole to connect to eye bolts, rod ends, and threaded rods. They’re commonly mounted upside-down between a tank and a leveling mount to weigh material in small tanks and silos.

IP66 Enclosure Rating—IP66 sensors stand up to spraying water.

Enclosure Rating—IP-rated sensors seal out dust.

Ready-to-Use Tension and Compression Force Sensors

Already calibrated, these sensors are ready to use right out of the box. Use them to measure forces in equipment by converting forces into electrical signals. They’re also used as the foundation within custom-built scales and force gauges, and to measure force in crash tests and other quality control processes. These sensors are also known as load cells.

When choosing a sensor, consider whether you’ll be measuring tension, compression, or both. Select sensors with a capacity rating higher than the greatest load you expect them to receive. They’re designed to briefly handle forces over their load capacity to protect from overload. Choose between a rectangle, round, S-shape, or cylinder sensor to best suit your application.

For the most accurate measurements, these sensors may need to be recalibrated.

It can also set off connected alarms or notify you when readings fall outside a set range. Export the data to Microsoft Excel and other analytical software such as MATLAB and LabVIEW. Wired PC connection kits come with a 6-ft. hub-to-PC USB cord.

Compression Force Sensors for Tight Spaces

Thinner than a credit card, these force sensors fit into narrow spaces to measure the applied load between two surfaces. While they’re less accurate than larger alternatives such as load cells and handheld force gauges, these will fit almost anywhere. Place them within an industrial press to make sure it’s operating in a safe range, or form them to the contour of a forklift seat to test the concept of adding a smart switch that detects when an operator is sitting and ready to operate the forklift. Sensors should be calibrated before first use. Also known as force sensing resistors.

Torque Sensors

Measure and record manually applied torque. These sensors convert torque into an electrical signal that your computer or programmable logic controller (PLC) can read.

PC Connection Kits—Sensors with a PC connection kit include software that plots and analyzes measurements, so you can track highs, lows, and averages over time. If measurements fall outside a certain range, the software can also set off alarms or send you an email. Export your data to Excel, MATLAB, LabVIEW, and other programs for analysis. Connect to a computer or tablet with the included USB cord.

PLC Connection Kits—Sensors with a PLC connection kit send signals to a PLC to trigger actions in your system, such as checking for proper fastening between joints or connections. They can also trigger robotic arms and other machinery to apply a precise amount of force.

Wireless PC Connection Kits—Sensors with a wireless PC connection kit also have a built-in transmitter that uses Wi-Fi to send signals to a USB receiver plugged into your PC.
