Signal Conditioning Instruments

Power Tech Equipments offers Signal Conditioning Instruments. Signal conditioning instruments specially developed for signal conditioning of wide varieties of transducers such as potentiometers, RTD’s, thermocouples, strain gauge bridges, proximity switches, magnetic or optical pick-ups, AC/DC voltages and current with complete optical and galvanic isolation between input and output. The various signal conditioners can be broadly classified into three types. Signal Transmitters: The purpose of current signal transmission is to achieve immunity to level drops from long runs and noise from motors, relays, actuators, transformers, switches, etc. Normally, these are built-in transducers. Signal Isolators: The purpose of galvanic isolation is to overcome ground- loop problem and to isolate high voltage plant side from the low voltage computer side / instrumentation panel side. This current signal is used in control room for the indication, control, data logging, data processing, etc. In case of isolators, normally output parameter is the same as the input parameter and more number of outputs with a single input is available. Signal Converters: Converts various field signal from RTD, thermocouple or other signals like current, voltage, frequency, resistance or any other parameter into electrical parameter. In this case, output parameter is normally not same as input parameter. Both isolated and non – isolated versions available.
