PCB® Series 8179 & 8180 Single Channel Telemetry Systems provide a simple, accurate method of conditioning and transmitting strain, thermocouple, voltage, or ICP® 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.
These Single Channel Telemetry Systems are 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. Power transmission to the rotor electronics and return signal transmission to the stator is accomplished via a transmission band wrapped around the shaft and used as an antenna. The flat antenna structure permits generous axial and radial clearance. Alternatively, power can be derived from an on-shaft battery.
Data is transmitted contact-free from the antenna to the stator and then to the control unit, where it is demodulated and converted back to an analog value. 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. PCB® Series 8180 performs a remote shunt calibration when the unit is powered up.
