Model QWLC-8M

Product catalog summary

Features:

Torque range from 25 in-oz to 300 in-lbs.
0.1% non-linearity and hysteresis.
Compact size with high frequency response.
Constructed from stainless steel with integral cable.

Description:

The Model QWLC-8M is a miniature reaction torque transducer designed for minimal size and maximum accuracy with 0.1% non-linearity. It uses four bonded strain gages to measure torque in both directions. The stainless steel construction ensures durability in harsh conditions, suitable for applications like motor dynamometers and friction-skid tests.

Performance Specifications:

Range: 25, 100, 250 in-oz; 50, 100, 300 in-lb.
System accuracy: ±0.1% full scale.
Linearity and hysteresis: ±0.1% full scale.
Non-repeatability: ±0.03% full scale.
Output: 2 mV/V nominal.

Environmental Specifications:

Operating temperature: -54°C to 107°C (-65°F to 225°F).
Compensated temperature: 16°C to 71°C (60°F to 160°F).
Temperature effect on zero and span: 0.005% full scale/°F.

Electrical Specifications:

Strain gage type: Bonded foil.
Excitation: 10 Vdc (5 Vdc for torque range <=100 in-oz).
Bridge resistance: 350 ohm.
Electrical termination: Teflon cable (1.5 m [5 ft]).

Mechanical Specifications:

Static overload capacity: 50% over capacity.
Case material: Stainless steel.
Deflection torsional: 0.0027 radians (25 in-oz to 50 in-lb), 0.00255 radians (100 in-lb to 300 in-lb).

Catalog excerpts

Miniature Reaction Torque Transducer Model QWLC-8M miniature reaction torque transducer is are en- gineered for minimum size and to achieve 0.1% maximum non- inearity. Four bonded strain gages are positioned on a special machined portion of the transducer to effectively measure even slight torque motion. These models operate and are calibrated in both directions. A modular, stainless steel construction and no moving parts provide excellent durability under harsh industrial conditions. Potential miniature reaction torque transducer appli- cations include motor dynamometer, tire braking, twist measure- ment, and friction-skid test measurements • Compact size • High frequency response • Stainless steel construction • Integral cable standard
