M-223-CD電導率變送器Conductivity Transmitter

The Model 223 Conductivity Transmitter with the appropriate sensor measures conductivity up to 2000mS/cm, resistivity in megohms and concentration in precent, ppm, mg/l or TDS. The basic transmitter is available with either a 115V AC or 220VAC or 24Volt AC/DC power supply, linear isolated current output and one alarm. Features include the addition of a second output for temperature and up to four alarms, which may be configured for on-off control functions, alarm limits, timer for cleaning or PID control functions. The PS version adds the diagonstic function Live Check as well as a non-linear programmable current output. Live Check signals an alarm when the sensor signal does not change over a defined period

Description
The Model 223 Conductivity Transmitter with the appropriate sensor measures conductivity
up to 2000 mS/cm, resistivity in megohms and concentration in percent, ppm, mg/l or TDS.
The basic transmitter is available with either a 115 VAC or 24 Volt AC/DC power supply,
linear isolated current output and one alarm. Features include the addition of a second output
for temperature and up to four alarms which may be configured for on-off control functions,
alarm limits, timer for cleaning or PID control functions. The PS version adds the diagnostic
function Live Check as well as a non-linear programmable current output. Live Check signals
an alarm when the sensor signal does not change over a defined period.
