OPERATION
The unit uses an RF Capacitance measurement technique for high
resolution measurements. When the presence of oil displaces the
water the level probe senses the decrease in capacitance and the
control unit will indicate an alarm condition and change the state of it’s
dry relay contacts.
USER INTERFACE
Instrument status 2 color indicator: Green for normal operation, Red = instrument error,
Red/Green (orange) for calibration confirmation.
Alarm Status Red indicator: On when not in alarm, Off when in alarm.
Time delay 0 – 20 seconds.
Relay action High or Low relay action. For high action, the relay is de-energized
under normal conditions and energizes when there is a presence of
oil. For low action, the relay is energized under normal conditions
and de-energizes when there is a presence of oil.
Dielectric switch Primarily used in high dielectric where there is a presence of water at
time of calibration.
PERFORMANCE
The unit measures capacitance in pF. Capacitance to Level
translation depends on the surroundings and the type of material
being measured.
Resolution Capacitance: 0.4% of measured capacitance. Example: at 50pF, the
resolution is 0.2pF and at 100pF, the resolution is 0.4pF.
SENSOR CONNECTION
2 wire + shielded cable from PMC 2000 to controller.
RELAY CONTACTS
Failsafe. DPDT 5A (resistive load) /250VAC/30VDC dry contacts.
Selectable high or low acting alarm.
POWER
115VAC or 220VAC @ 25mA max.
24VDC @ 60mA max.
