Supported Applications
The Omega TQ201/TQM201 Series comprises in-line mount reaction torque sensors designed to be mounted directly to the torque-producing element. These devices are engineered for measuring the starting torque of motors and other non-rotating applications where a fixed sensor measures the reactive force.
Operating Conditions & Performance
The series delivers high accuracy with an Accuracy Class of ±0.2% FSO, Linearity of ±0.15% FSO, Hysteresis of ±0.10% FSO, and Repeatability of ±0.03% FSO. Zero Balance is specified at ±2% FSO. The sensors operate within an ambient temperature range of -54 to 107°C (-65 to 225°F), with a compensated temperature range of 16 to 71°C (60 to 160°F). Thermal effects are rated as Zero: ±0.005% FSO/°F and Span: ±0.005% rdg/°F.
Electrical performance includes an output signal of 2 mV/V with a recommended excitation voltage of 10 Vdc (maximum 15V). Both Input Resistance and Output Resistance are specified at 350 Ω minimum. The sensors feature Safe Overload capability up to 150% of capacity and Ultimate Overload protection up to 300% of capacity.
Configuration Options
The TQ201/TQM201 Series is available in standard (inch-pound) and metric models covering reaction torque ranges from 0-25 oz-inch to 0-1000 inch-lb, or equivalently 0-0.18 N-m to 0-113 N-m depending on the specific model selection.
Key configuration details include:
- Housing Material: All stainless steel construction for long-term reliability and heavy-duty mounting ensuring a non-slip connection.
- Protection Class: IP65 rated enclosure.
- Electrical Connection: 1.5 m (5') 4-conductor shielded PVC cable with strain relief for low-noise measurements.
- Dimensions by Range:
- 25 oz-inch to 250 inch-lb: 38 mm (1.50 in) diameter, 38 mm (1.50 in) length
- 500 inch-lb to 1000 inch-lb: 51 mm (2.0 in) diameter, 38 mm (1.50 in) length
- Certifications: NIST Standard and RoHS compliant.
Key Product Differences
The series distinguishes between standard inch-pound models (TQ201) and metric models (TQM201). Model numbers follow the format TQ201/TQM201 Series - <RANGE>. Specific model examples include TQ201-30Z for a 30 oz-in range, TQ201-250 for a 250 in-lb range, and metric equivalents such as TQM201-0.7 (0 to 0.70 N-m) or TQM201-113 (0 to 113 N-m). The series supports various ranges including 0 to 25 oz-in through 0 to 1000 in-lb, with corresponding metric equivalents ranging from 0 to 0.175 N-m up to 0 to 113 N-m.
