Signal Conditioning Instruments

|
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. |
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. |
