PermAlert - Model PWS -Water Based Liquid Probe

The PWS probe detects all conductive liquids - water, acid, bases, chemicals, etc. Its solid-state, stainless steel construction allows it to be used in corrosive environments and reset quickly after removal from a liquid.

The unique design of the PWS probe eliminates the need for external power at the probe.

PWS probe is available for the PAL-AT or LiquidWatch system.

The PWS probe for the PAL-AT can easily be connected to a cable "sensing string" providing increased utilization of the PAL-AT capabilities. Each probe assembly includes a probe integrator with 60 ft (18 m) of jumper cable to connect to the sensing string, 20 ft (6 m) of lead wire to attach the probe to the probe integrator and a NEMA 4X junction box.

NOTE: A PWS probe cannot be installed on a sensing string connected to a PAL-AT ZBA Zener barrier assembly (in hazardous areas)

The PWS probe for Liquid-Watch includes a probe adapter and ½” NPT cord grip. Additional lead wire is used if necessary.

PAL-AT Note:

• A "-S" probe must be connected in the first 5,000 ft (1,500 m) of the sensing string.
• A "-L" probe must be connected more than 5,000 ft (1,500 m) from the PAL-AT panel.
• Each probe integrator includes junction box, two connectors and three ½” NPT cord grips.
