Depth Tracker Transducer Probes
Description
The Depth Tracker Liquid Level Industrial Transducer Probe
(ITP) is used to provide a current signal proportional to the
vertical liquid level. A remote programmable controller
(PLLC) or microprocessor functioning as a switching
mechanism can convert the signal transmitted.
This device is for use with refrigerant R-717 (ammonia) only.
It may be used with liquid temperatures in a range of
-77° to 57° C (-107° to 135° F). The minimum ambient for
circuit board enclosure is -29°C (-20° F).
●
Probe lengths: 2, 3, 4, 5, 6, 7, 8, 10 & 12 feet
●
Integrated construction achieved by molding the PTFE
sleeve directly to the center rod
●
Electrical connection via 3/4” conduit boss or jacketed
communications cable of suitable temperature/moisture
protection
●
Fully potted circuit board
●
Local or remote digital read-out options
●
Optional display riser accommodates column insulation
●
Unique probelok connection option
●
Factory pre-calibrated for ammonia for 0-100% level
output in 4" IPS Standpipe. The electronics may be re-
calibrated in the field to permit viewing of liquid level over
any segment representing more than 40% of the probe’s
overall length.
●
All wetted parts are stainless steel construction to
prevent corrosion
