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.

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.

Round


Button	Dual-Sided Threaded Stud

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

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.

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

Ready-to-Use Tension and Compression Force Sensor Kits

With a sensor that’s already calibrated and everything you need to relay data, these kits come ready to operate. Use them to measure forces in equipment and send the data directly to a computer or programmable logic controller (PLC) to monitor, document, and trigger actions in machinery. 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.

PC Connection Kits—PC connection kits link to a computer, tablet, or LCD display. All include a calibrated force sensor, a data conversion hub, and data-recording software. The conversion hub turns electrical signals from the sensor into usable force measurements. The software plots and analyzes measurements, so you can track high, low, and average values over time. 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.

PLC Connection Kits—PLC connection kits send an analog signal to your PLC to trigger actions such as diverting items that exceed a certain weight on a conveyor. They include a calibrated sensor and a data conversion hub. They’re not for use with LCD displays.

Wireless PC Connection Kits—Wireless PC connection kits transmit data over Wi-Fi to your computer from their conversion hub without a cord.

Enclosure Rating—IP rated sensors seal out dust.
