Tension Force Gauges for Wire and Filament

Measure the tension of wire and filament without pausing your operation. These gauges are often used to set tension and take continuous readings in 3D printing, spooling, wire cutting, and drawing machines. They can also be used with thin wire rope, carbon fiber, and fiber-optic strands. Slide your material between the three rollers to take measurements, even in tight spaces. All include a calibration certificate traceable to NIST that states these gauges meet standards for accuracy. They include a case for storage and protection.

Large-Capacity Digital Tension Force Gauges with Scale

Measure tension force as well as weight. These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. All are NEMA 4X rated for protection from dust, water, and mild corrosives. They can be manually reset to zero and have a peak-hold setting that retains the highest reading on the display when activated. Also known as dynamometers.

Robot-Ready Force Torque Sensors

Mount these sensors between a robot arm and a tool for precise control during delicate tasks, such as sanding or assembling small parts. They constantly measure the force and torque your tool is applying to a workpiece, mimicking your sense of touch. As they measure the force and torque in six axes (three for force and three for torque), they send the data to your robot controller, which uses it to judge the tool's position and adjust the arm's movements. The constant communication between the sensor and controller helps you automate tasks that would normally require a person.

These sensors are UR+ Certified, which means they work seamlessly with Universal Robots (UR) systems. They have an ISO 50 mounting pattern to connect to most tools without an adapter. These sensors are more sensitive and accurate than built-in UR sensors, since they have an accuracy of ±2%. Switch between calibration settings for small and large loads for the most accurate measurements for the force in your application.

Install the data-recording software onto your teach pendant to integrate these sensors with your robot. The software helps you program, record, and control the forces of your assembly. LED status indicators show you whether the sensors are working, so you don't need to check your controller. They also have silicon strain gauges, which send a strong signal to your controller with very little distortion. Rated IP64, these sensors are dust-tight and protected from water splashing in all directions.

Washdown Legal-For-Trade Floor Scales with Remote Display

Scale

Ramp

These scales are NTEP approved as legal for trade and have an IP69K rated load cell for use in washdown environments. They withstand exposure to dust and moisture, including the frequent high-pressure, high-temperature washdowns commonly used in outdoor industrial environments, food processing facilities, and chemical plants. Plus, the scale-to-display junction box meets NEMA 4X standards for protection against washdowns and corrosion.

Also known as platform scales, these have a low profile so you only need to lift heavy objects 3" off the ground. Their stainless steel construction and a ribbed structural underside give them the necessary support to weigh thousands of pounds at a time. To keep items in place, a diamond tread on the platform provides slip resistance. The load cells in these scales are FM approved, so they’ve been tested for quality and safety by Factory Mutual.

Subtract the weight of a container with the tare function to weigh only the material inside. Use the counting mode to keep a running tally of how many items are on the scale.

Mount the remote display at a distance on a workstation, column, or wall—the connecting cable is 22 feet long. The backlit display features 1"-tall digits for easy reading.

Install optional ramps to slide or wheel heavy loads onto scales. If you install two ramps, they must be on opposite ends.
