High Bandwidth Telemetry Transmitters
ATi’s 2100H Series Telemetry systems are ideal for transmitting high speed data signals from sensors, which are mounted on rotating shafts or machinery to a stationary receiver. The 2100H Series Miniature Transmitters modulate sensor signals from strain gage bridge circuits, thermocouples or voltage transducers onto a RF carrier and transmit them to a stationary receiver.
The 2100H Series Transmitters incorporate a crystal oscillator that is tuned to a specific frequency of one hundred possible frequencies in the 900MHz band, eliminating the need for tuning by the end user. Transmitter frequencies can be staggered allowing multiple transmitters to be operated in close proximity with no interference. This allows for multi-channel systems or multiple systems to function within the same area.
Power to the transmitter can be supplied by a nine-volt battery or a rechargeable Li-Ion battery pack. The 2100H Series Transmitters incorporate an internal power, temperature and status monitor, which provides constant feedback to the operator via the receiver’s multi- function display.
Transmitters are available in a number of different sizes and shapes to fit most any purpose. Custom configurations can be designed for particular applications.
The 2125H Series Receiver demodulates the signal and converts it to a ±2V, ±5V, ±10V or 4-20mA analog output. A wide band analog output provides frequency response from DC to 5000Hz. An optional filtered output is available for maximum stability.
The 2125H Series Receivers also remotely control the transmitter’s On or Sleep status and activate the Bipolar Shunt Calibration feature. An “All” function allows for control of all transmitters in range from a single receiver.
Transmitters are small enough in size to be taped or strapped to a rotating shaft or they can be used with a 2110H Series Collar Assembly for quick and easy installations. The collar assembly can be designed to clamp or bolt directly to existing shafts, or other components. The collar assembly houses the transmitter and battery, as well as, an integral transmitting antenna.
