Instruments for processing data from position sensors
A position-sensing amplifier (PSA) processes the signal produced by a position sensor and produces an output signal correlated with position.
A position-sensing indicator (PSI) combines a position-sensing amplifier and display module in a single instrument, in order to provide a direct positional readout.
The following table summarizes key specifications for UDTi's position-sensing instruments. Links in the left-hand column lead to more detailed specifications for each individual instrument. Compatibility with various UDTi position sensors is addressed on our Position Sensors page. Further information is given in the Position-Sensing System Configuration Guide.
