Torque Calibrators & Testers

The 20/80 rule for torque recommends applying 20% of the target torque in the first pass and 80% in the final pass when fastening bolts or assemblies. This staged tightening approach distributes clamping force evenly, reduces the risk of joint distortion, and ensures consistent and repeatable torque application across critical fastening operations.

SensorData Technologies offers reaction (static), rotary transformer/magnetic, true wireless (Bluetooth), and slip ring torque sensors. These cover capacity ranges from 50 oz-in to 1,000K lb-in and speed ratings up to 35,000 RPM, supporting applications from bench calibration to high-speed engine and driveline testing.

A dual-range torque sensor can measure two different torque ranges using a single transducer, with measurement ratios up to 5:1. It is ideal when a test application requires both low and high torque measurements, such as calibrating torque wrenches across multiple capacity ranges, reducing the need for multiple instruments and improving efficiency.

SensorData torque calibrators and sensors are compatible with AC carrier and DC strain gage signal conditioning electronics. The Strain Gage Bridge Simulator Model i100 is entirely passive and requires no external power, while transducers like the T171-231 feature on-board proprietary signal conditioning with ±10 VDC output and 1 KHz bandwidth.

Yes. SensorData Technologies provides free in-house calibration when torque sensors are purchased with SensorData electronics. If customers supply their own electronics, in-house calibration is available for a fee. The Strain Gage Bridge Simulator i100 also receives free in-house calibration when purchased as part of a complete system.

SensorData torque calibrators and testers serve automotive, aerospace, defense, and industrial manufacturing industries. Applications include calibration of hand-held torque wrenches, in-line testing of motors, engines, transmissions, and pumps, life testing of driveline components, high-speed aircraft fuel pump test stands, and quality control in material testing facilities.
