The CD1140 series of contactless torque sensors from FGP Sensors and Instrumentation, available from Bestech Australia , offer a rugged but small package size as well as many mounting configurations that provide measurements in both industrial and laboratory environments. The torque transducer has been used in the subsea oil and gas industry.
The contactless transmission of supply voltage and measuring signal facilitates continuous operation with minimum wear and no slip ring service. A single voltage supply of 12V DC is required and power consumption is less than 200 mA. The unit can operate at temperatures between 0°C and 60°C.
There are various models of the CD1140 torque sensors, from the 0.05 Nm to the 20,000 Nm full scale range. The sensor measures to high accuracy, exhibiting a linearity of 0.1% of full scale range and hysteresis of 0.1% full scale range. The sensor has a small outline and low moment of inertia.
The CD1140 contactless torque sensor is also available with optional speed or angle detection. This torque sensor is available in Australia and New Zealand from Bestech Australia.
