load cell for roller

Product catalog summary

Overview: The T/er-Series Live Roller Load Cells are designed as a versatile alternative to the T-Series Idler, suitable for both existing and new roller installations. They feature stainless steel construction, sensitivity to varying tension levels, and 360° beam overload stop protection. The load cells are equipped with ER bearings to match standard bores and can accommodate shaft expansion, misalignment, and bending.

Specifications: The load cells operate with a 5 VDC excitation and provide a nominal output of 250 mV at full load. They have a gauge resistance of 80-130 Ω and are classified under IP54 for environmental protection. The operating temperature range is -4˚ to 150˚F (-20˚ to 70˚C), with a temperature coefficient of 0.02% per ˚F. Mechanical deflection ranges from 0.008 to 0.015 inches, and alignment tolerance is 1˚ max.

Models and Dimensions: Various models are available, including ST0-L, ST2-L, FT0-L, FT2-L, PT0-L, PT2-L, PBT0-L, and PBT2-L, each with specific dimensions and weights. For example, the ST0-L model measures 4.39 x 2.66 x 2.66 inches and weighs approximately 3.00 lbs.

Installation and Configuration: The load cells can be mounted using different configurations such as flange, pillow block, or split pillow block. The connector position is adjustable, with standard positions at 6 o'clock for S & F mounts and 3 & 9 for a pair of P mounts. Load ratings vary by size, with size 0 supporting up to 150 lbs and size 2 up to 500 lbs.

Operational Details: The load cells utilize tension and compression strain gauges in a bridge configuration to measure web tension. The unique joint design includes a high-performance spherical bearing assembly to accommodate misalignment and roller deflection. The load cells are designed to be inserted into the bearing bore of rollers, eliminating the need for additional shafts and bearings.

Recommendations: For optimal performance and safety, it is recommended to consult a Montalvo Application Specialist to select the appropriate product for specific applications. Roller preparation to accept specified bearings is critical, and preparation drawings are available upon request.
