Thiết bị đo mức chất lỏng Nixon LT Liquid Level Gauge & Transmitter
Working pressure manufacturing according to
PED 97/23/CE (Lloyd’s Register Certificate Nº 031)
Simply constructed and resistant to adverse conditions of
temperature and pressure. Materials in EN 1.4404 (SS 316L),
PVC, PP, PVDF or PTFE for most applications in industries
such as:
• Chemical, petrochemical and other processes
• Refrigeration, Retorts and Heat Treatment
• Boilers, marine & industrial
• Evaporators & Condensers
• Storage Tanks
Features
• Full process isolation, no risk of leakage
• Alarms contacts adjustable over the full range
• Clear indication with magnetic float or magnetic strips
• Transmitter output 0...4-20 mA
• Excellent chemical and mechanical resistance
Operation
A vertical measuring chamber, connected to the tank at
each end, contains a magnetic float that rises and falls
with the liquid level. An indicating chamber is attached, but
not directly connected, to the measuring chamber. The
indicating chamber contains a magnetic strips indicator
or magnetic float that follows the position of the float in
the measuring chamber to provide an indication of the
tank level.
Adjustable contacts, actuated by the float’s magnetic field,
can provide switch points for control or alarms. A sensor
detecting the float position can provide a 4-20 mA signal
for proportional control.
