電導(dǎo)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
