Monitors liquid level from outside of plastic or non-metallic tanks.

Product Features and Benefits:

IMPROVES PROCESS CONTROL:

• Provides automated control and consistent liquid levels for most aqueous processes and waste treatment tanks or when leak detection is required.

• Adds protection against fires and tank damage associated with low-level conditions.

• ESP model: mouints on the outside of plastic tanks and senses up to .984 inches (25mm) so no direct immersion is required.

• ESPV model: for direct immersion applications (vertically mounted).

CORROSION RESISTANT ENCLOSURES:

• ESP model: housed in a plastic, epoxy encapsulated enclosure with 6-foot (1.8m) flexible cord and mounting flange.

• ESPV model: vapor tight, polypropylene probe enclosure with 3-foot (.9m) flexible PVC conduit.

CERTIFICATIONS: UL, CSA and CE.

CAPACITIES:

• Field selectable normally open or normally closed.

• 500 mA switch capacity (10 mA minimum).

• Operates on any voltage between 90 and 265 VAC, 45 to 65 Hz.

• Ambient temperature range: 0°F (-18°C) to 176°F (80°C).

• Single phase only.

OPTIONS AVAILABLE (consult factory):

• ESPV models available with heavy wall immersion tubes in: CPVC, PVDF, PTFE, and quartz for vertical mounting.

• Custom length immersion tubes for ESPV models.

• Can be pre-wired into combination temperature controls.

• Longer flexible conduits for ESPV devices.

• Threaded wells for through tank wall applications.
