Detecting potential pump damage
April 1st 2008 ifm electronic has a new line of
pump diagnostic pressure sensors
that detect potential pump
damage caused by cavitation,
trapped air or gas, blockages and
deposits.The PIM Series pressure
sensor can perform both pump
monitoring and pressure detection.
It monitors a pump to provide
operating system pressure and
continuous diagnosis of the pump's
condition. Operating as a pump
diagnostic sensor, the PIM sensor
stores the pulsation of a properly
operating pump as a reference to
detect any changes. If a critical
pump condition occurs an alarm
signal sounds. ifm's conditionbased
pump monitoring sensor
increases machine uptime and
reduces damage caused by poor
pump operating conditions.
Disturbances around the pump
such as trapped air in the medium,
clogged filters, deposits in pipes or
improperly opened valves are also
monitored.
Due to the high overload
resistance of the ceramic capacitive
measuring cell, the sensor is
especially suited for switch-off in
case of overpressure. FDT
programming software enables the
display of the measured values,
analog output, limit values and the
parameter setting of the thresholds
for diagnosis.
The stainless steel PIM pressure
sensor is designed for sanitary
applications and is 3A authorised. More articles from ifm electronic Limited: |
