Check the pressure on your drinking water system with these gauges—they meet NSF/ANSI Standard 61 for safe use with potable water. The dry dial on these gauges is best for low-vibration applications, since the needle can bounce if the gauge is shaken. For more accurate readings under heavy vibration, use a liquid-filled gauge. Mount gauges with the dial face upright.

Remote-Reading Tension Force Gauges

Gauge

Gauge with Heat Shield Disc and Jacket

Receiver Display

Safely view your tension force measurements on a handheld receiver up to 450 ft. away when moving bulk material with cranes and hoists. These gauges are also called dynamometers and crane scales. Made of steel, they’re durable enough to briefly hold heavy loads up to 500% of their capacity. But, they will no longer take measurements if the load exceeds 200%. Warning lights will flash first when your load exceeds capacity, then again when it reaches 133% capacity. To prevent overloads, the peak-hold setting displays the highest measurement. The tare function lets you reset the gauge to zero after attaching a container to weigh only the material inside. These gauges include a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. They also meet IEC and ASME safety and fatigue standards.

Because their indicators and load cells are IP rated, these gauges stand up to washdowns and brief submersion common to food and chemical plants. They’re also safe to use outdoors since they’re NEMA rated to seal out weather.

These gauges come with two shackles that work with other lifting fittings, such as clevis hooks. The included batteries power their load cells for up to 2,000 hours.

Gauges with a heat shield disc and jacket hold up in foundries and other hot environments because their load cells take longer to reach the maximum temperature than other gauges. An internal thermometer tells you the load cell temperature on the receiver.
