VZ230

Moisture and Temperature Measuring Instrument

  • Continuous on-line measurement of moisture in insulating oils
  • Ball valve installation - no need to shut down the process
  • Incorporates Vaisala HUMICAP® Sensor - excellent long-term stability
  • Integrated data logging, with over four years of measured history
  • LAN communication (RJ45 10/100Base-T)

 

 

  • additional ports for external sensors for 0..10VDC, 4..20mA or PT100
  • 6 additional potentional free contacts (relays) for setpoint or alarm communication
  • Power supply 230VAC, 50/60Hz
  • shock proofed housing with internal cooling fan (IP65 if closed, needs to be open for operation)
