Supported Applications
The Omega TQ202/TQM202 Series consists of small, high-accuracy flange- or surface-mount devices designed for measuring reaction torque forces. These sensors are engineered to ensure long life in industrial environments and maintain long-term accuracy through all stainless steel construction.
Operating Conditions & Performance
The series delivers an output signal of 2 mV/V with a combined linearity, hysteresis, and repeatability accuracy of ±0.2% FSO. The compensated temperature range is specified as 16 to 71°C (60 to 160°F), while the operating ambient temperature extends from -54 to 107°C (-65 to 225°F). Thermal effects are rated at 0.005% FSO/°F for zero and 0.005% rdg/°F for span.
Electrical specifications include an excitation voltage of 10 Vdc with a maximum of 15V, an input resistance minimum of 360 Ω, and an output resistance of 350 ±5 Ω. The sensors feature IP65 protection class ratings and are supplied complete with a 5-point calibration.
Overload capabilities are defined as follows:
- Safe Overload: 150% of capacity
- Ultimate Overload: 300% of capacity
Configuration Options
The TQ202/TQM202 Series is available in multiple measurement ranges to accommodate specific torque requirements. The series supports both inch-pound and metric configurations, with model numbers indicating the range capability.
- Inch-Pound Ranges: 0 to 25 oz-inch through 0 to 250 inch-lb
- Metric Ranges (TQM202): 0 to 0.175 N-m through 0 to 28 N-m
The physical design features a flange-to-shaft mount configuration with the following dimensions:
- Diameter: 38.1 (1.5) DIA.
- Height: 57 (2.25)
- Shaft Diameter: 9.5 (0.38) DIA.
- Flange Hole Spacing: 6 HOLES EQ. SP. ON A 47.6 (1.875) DIA. B.C.
The shaft attachment includes three equally spaced flat surfaces to ensure non-slip mounting without the use of a key. Electrical connection is provided via a 1.5 m (5') 4-conductor shielded PVC cable with strain relief. The series holds NIST Standard and RoHS certifications.
Key Product Differences
The product line distinguishes between inch-pound models designated as TQ202 and metric models designated as TQM202, though both share the same physical construction and performance specifications. Model numbers follow a guide format of TQ202/TQM202 Series - <RANGE>, such as TQ202-25Z for 25 oz-inch or TQM202-0.175 for 0 to 0.175 N-m.
Compatible meters listed in the documentation include DP41-S and DP25B-S models, which are referenced alongside specific range options in the ordering table.

Show Ratings & Reviews
Does this sensor measure torque in both directions? And if not, how are we supposed to know which direction is the measurement range? We have built this sensor into a device and our customer is saying they are only reading torque in one direction.
The TQ202 is only calibrated in the clockwise direction but it will read in both directions. If wired as indicated on the included calibration report you will see a (+) positive polarity millivolt output signal when torque is applied in the clockwise direction. If you apply a load in the counterclockwise direction you will see a (-) negative polarity millivolt output signal which would be a mirror image of positive signal. The instrumentation your customer is using may be set up to read only a positive polarity signal.
