Sensorless pump monitoring
- Power factor
- Data sheet:
- Three operating conditions should be monitored for a chemical pump:
* Dry running
* Mislaid input filter or no intake
* Lower density through heating of the medium
- The G4CM690V16ATL20 cosinus phi monitor from TELE reliably measures the power factor of the motor and switches the control output when it falls below a predefined level. A second switch value can be used as advance warning in order to prevent a fault.
- * Minimization of outages of the pumps through prompt shutdown
* Recognition of mislaid/worn filters
* Recognition that the medium is becoming warmer (density)
* No additional sensors needed* Simple wiring and simple settings
* Easy to retrofit
* Economical monitoring of aggressive, hot, explosive media
* Start-up conditions are hidden as defined
