Rechargeable Li-Ion Battery Telemetry Systems

ATi’s Rechargeable Telemetry System offers more performance and features while providing solutions to common shaft mounted obstacles. Separate but simultaneous data and status signals allow a variety of control functions independent of the high quality data stream ATi is known for. Battery power means lower noise floors, more versatile installations, no active power generation or tuning.

The newly designed 2140RB Series Telemetry Transmitters feature a contoured profile, which reduces radial and axial clearances required for installation. Transmitters are available for any type of measurement. Transmitter operation is remotely controlled from the 2125B Receiver, limiting the need for access to set switches or make DMM measurements.

Manufactured from fiberglass composites, the 2110RB Telemetry Collars can be used to house the transmitter and battery for easy installation. Collars require only 0.65” (16.5mm) radial and 2.5” (63.5mm) axial clearance allowing them to be placed almost anywhere on the shaft. Single or multi-piece collars mount to the rotating part and transmit the signal to a stationary receiver. The 2140RB Miniature Strain Gage Transmitter can be connected directly to strain gages adhered to a shaft, converting it into a torque sensor. Since the system is wireless, it can transmit shaft torque while the shaft is turning.

Often used as a testing tool by automotive and racing engineers to obtain real-time torque measurements from vehicle drivelines; the system can be installed on most any size shaft and is completely field installable by the end user. A rechargeable Li-Ion battery pack supplies power for about 25 hours of continuous run-time to the transmitter. The system comes with a spare battery pack and charger, so that power is always available.

The Model 2125B Receiver features a new programmable, multi-function, digital backlit display. Transmitter mode (On/Sleep/Off) and remote calibration (+/-) are selected from menu based display. The receiver can be powered from 12 VDC or 120 VAC and provides an analog output for use with any data acquisition system.
