Probes
1.PWS - Water based liquid probe
The PWS probe can easily be connected into a PAL-AT "sensor
string" providing increased utilization of the PAL-AT
capabilities. Each probe assembly includes a probe integrator
with 60 feet (18m) of jumper cable to connect to the sensing
string, and 20 feet (6m) of lead cable to attach the probe
to the probe integrator.
The
unique design of the PAL-AT probe integrator eliminates
the need for additional power at the probe. Its solid-state
stainless-steel construction allows the PWS probe to respond
to all conductive liquids - water, acids, bases, chemicals,
etc. The probe resets quickly after resets quickly after
removal from the liquid.
2.PHL

"sensing string" providing increased utilization
of the PAL-AT capabilities. Each probe assembly includes
a probe integrator with 60 feet (18m) of jumper cable
to connect to the sensing string, and 20 feet (6m) of
lead cable to attach the probe to the integrator.
The
unique design of the PAL-AT probe integrator eliminates
the need for additional power at the probe. Its patented
solid-state construction allows the PHL probe to respond
to most liquid hydrocarbons but ignore vapors, thus virtually
eliminating false alarms due to vapors. PHL is responsivve
to a broad range of fuels and solvents. The probe resets
quickly after removal from exposure to most volatile hydrocarbons.
3.PHFW
- Monitor well probe
The PHFW monitoring well probe can easily be connected
into a PAL-AT cable "sensor string" providing
increased utilization of that PAL-AT capabilities. Each

of jumper cable to connect to the sensing string, and
20 feet (6m) of lead cable to attach the float switch
to the probe integrator.
The
unique design of the PAL-AT probe integrator eliminates
the need for additional power at that probe. The TankWatch
probe includes a junction box and contact adaptor in lieu
of the probe integrator.
The
PHFW is designed for use in 4 inch (100mm) monitoring
wells where the sensor can hang vertically, extending
into the water table to the bottom of the well. A weight
attached to the sensor keeps it taut. The sensor filament
responds to contact with selected hydrocarbons floating
on the water by breaking, and/or releasing the weight,
activating a switch. The probe is easily reset by replacing
the filament.
4.PHFW-M
- Monitor well probe
The PHFW-M probes are designed for use in applications
such as manholes and fuel pits, where the sensor cable
must detect hydrocarbons within .25 inch (6.5mm) of the
bottom of the monitored area. If water enters the monitored
area any fuel leaks will float on the water and be detected
by the sensor. The probe's operation is identical to the
PHFW probe and it includes a length of slotted PVC pipe
to mount the probe.
5.PFS
- Float Switch
The PFS float switch can easily be connected into a PAL-AT
cable "sensor string" providing increased utilization
of the PAL-AT capabilities. Each assembly includes a probe
integrator with 60 feet (18m) of jumper cable to connect
to the sensing string, and 20 feet (6m) of lead cable
to attach the float switch to the probe integrator.
The
unique design of the PAL-AT probe integrator eliminates
the need for additional power at the probe. The TankWatch

FluidWatch®
•The FluidWatch Leak Detection Monitoring Unit is engineered
to monitor small areas for water leaks. Typical applications
include unmanned equipment rooms, small raised floor areas
and small tanks. The system continuously monitors the capacitance
of the sensor cable and detects changes. Seconds after the
coaxial sensor cable contacts water or water-based liquids,
the unit enters into alarm. The sensor cable can be quickly
dried in place after the leak is cleaned up and the system
is back on-line.
FluidWatch
uses an LED "traffic light" display to indicate
status: green - normal; yellow - break; and red - leak.
An audible alarm and two 250 VAC, 10A, SPDT activate relays
when either a leak or break occurs. There are two operator
buttons, one to test the system and the other to silence
the alarm.
Internal
jumpers are used to enable alarm silencing, to select
cable sensitivity and to enable automatic silencing upon
return of the system to normal conditions.

TankWatch®
•TankWatch PHMS Single Channel and PHM 10 Multi Channel
probe monitoring units are engineered to meet a broad range
of customer needs. The multi-channel system can be configured
from one to 10 channels, with each channel capable of monitoring
one dual probe or two single probes. The multi-channel modular
design allows expansion to ten (10) channels by plugging
in channel expansion cards and connecting probes. Modular
construction permits plug-in pull-out service ease.
TankWatch
employs an understandable "traffic light" display
for status indication: green - normal; yellow - break;
and red - leak. The unit enters into an alarm mode on
any red or yellow condition, activating an audible alarm.
A leak activates the system relay for external alarm or
control functions. There are two operator buttons. One
is used to test the system and other other to silence
the alarm. This silence button can be disabled, via an
internal jumper, to prevent unauthorized silencing.
TankWatch
units are equipped with normally energized, 10 A, 240
VAC, DPDT relays; one relay for PHMS, four relays for
PHM10. Any or all relays can be field set to respond to
leaks. The alarm console can be located up to 5,000 feet
from the probes. The system relays can activate an optional
remote alarm.
Patented
compact probes for TankWatch are solid-state design and
respond in seconds, after contact with organic liquids
or water. Hydrocarbon fumes or vapor have no effect, thereby
virtually eliminating false alarms. There are probes available
for monitoring ground water, brine levels in underground
storage tanks and float switches for high/low level.
TankWatch
can also monitor any switch (float switch, thermostat,
high level switch, etc.) that is connected to the optional
contact adapter.
