We Provide 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.
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.
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.
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.
|Galvanic isolation||500VDC / 1KV RMS (In Case of isolators)|
|Linearity||Better than 0.3% over full scale.|
|Zero and Span adjustment||Provided by means of trim - pot (external / internal)|
|Termination||Suitable for 2.5 mm square conductors|
