January 11, 2010 – PCB Load & Torque, Inc., introduces their new Series 8179 Universal Single Channel Telemetry Systems. These systems provide a simple, accurate method of transmitting strain torque, thermocouple or voltage signals on rotating or moving machinery while operating in a completely contactless mode. Power is transferred inductively and the signal is RF-transferred between the moving and static component – no brushes or wires required. This method guarantees an absolute maintenance-free continuous operation and accurate transmission of measured data. The Universal Single Channel Telemetry System is compact in size and light weight which allows for quick and easy installations in areas where space is at a premium without affecting the dynamic properties of the shaft. The universal receiving electronics allows the user to power and condition strain gage, thermocouple, or voltage sensors from a single module. Power transmission to the rotor electronics and return signal transmission to the stator is accomplished via a transmission band wrapped around the shaft. Alternatively, power can be derived from an on-shaft battery. Data is transmitted contact-free from the transmission band to the stator and then carried to the control unit, where it is demodulated and converted back to an analog value. An optional hoop antenna is available in lieu of the stator to allow for greater articulation of the measured shaft. The signals can be read directly on the control unit display or fed into further acquisition equipment. PCB® Series 8179 also includes a remote shunt-calibration feature that enables strain gage configurations to be checked, even during measurement. |
