This allows the user to check calibration at any time during system operation. When the shunt calibration feature is invoked, a precision resistor is switched across one leg of the Wheatstone bridge, producing a positive shift in the receiver’s output.

Proper mechanical installation of the TORKDISC rotary torque sensor system is critical to ensure proper operation and long-term life. Read this entire section before installing the system. When in doubt about application, consult the Load & Torque Division of PCB Piezotronics prior to proceeding. CAUTION This wireless data acquisition system contains delicate electronic components that must be protected from excessive shock and prolonged exposure to water, oil, or other chemical contaminants.

3. Connecting drive shafts usually can be bolted directly to the TORKDISC through use of an adapter, without need for additional support, assuming that the resultant bending moment on the TORKDISC does not exceed the specified limit. Request specification sheets from PCB to determine the maximum permissible bending moment of a given TORKDISC model.

To maximize measurement accuracy, allow the system to warm-up for at least 30 minutes prior to performing a calibration procedure. When calibrating the system, the transmitter’s input must be connected to the transducer. PCB Load & Torque Toll-Free in USA 866-684-7107 716-684-0001 www.pcb.com...
3. Apply the shunt calibration by pressing the switch located on the front panel of the receiver. The green SHUNT CALIBRATION indicator is illuminated. Alternately, gain adjustment can be made using a dead weight calibration or other mechanical stimulus as the reference. PCB Load & Torque Toll-Free in USA 866-684-7107 716-684-0001...

Standard calibration certificates list five force points ascending and four points descending. Additional data points are available at extra cost upon request. If an initial evaluation shows that a transducer requires repair, PCB will provide the customer with an estimate prior to taking any corrective action.
