Weigh and measure tension force at a safe distance, up to 450 feet away, with these wireless gauges. Also known as dynamometers and crane scales, they’re used with cranes or hoists while moving material around your plant. With a low overall height, they can be used indoors in areas with limited headroom. They can also be used outdoors because they’re NEMA 4 rated, which means they’re weather tight for protection from rain, snow, and ice. Their IP65 rating protects them from dust, splashing water, and low-pressure washdowns, such as from a garden hose.

A peak-hold setting continually displays the highest readings, so you can make adjustments to prevent overloads. A tare function lets you reset the gauge to zero after attaching a container to weigh only the material inside. All include a calibration certificate traceable to NIST that states they've passed a test to confirm accuracy. If you accidentally place a heavy load on these gauges, they’re durable enough to handle it; they withstand a temporary load up to 500% of their capacity. The ability to take accurate readings, however, may be permanently impaired if loads exceed 200% of their capacity. To meet safety and fatigue standards, these gauges are IEC 61508 and ASME BTH-1 rated.

Gauges come with two shackles that accept other lifting fittings, such as clevis hooks. They operate on batteries, which can power their load cells for up to 2,000 hours.

Use single-point gauges to take measurements and view them on a handheld wireless receiver. All have two-level warning lights—they flash the first warning when your load exceeds capacity, and then again when it reaches 133% of capacity. Choose gauges with a heat shield disc and jacket when working in hot environments, such as a foundry. With the added heat protection, their load cells take longer to reach their maximum temperature than other gauges. They also have an internal thermometer that lets you see the load cell temperature on the receiver.
