Specifications

Service:

Liquids, powder and bulk materials compatible with wetted materials.

Wetted Materials:

316 SS and polyvinylidene fluoride (PVDF).

Temperature Limits:

Ambient: -40 to 185°F (-40 to 85°C), -4 to 185°F (-20 to 85°C) with under 24 VAC/DC power supply;
Process: -40 to 250°F (-40 to 121°C).

Pressure Limit:

365 psi (25 bar).

Enclosure Rating:

Weatherproof, NEMA 4X.

Switch Type:

DPDT (two form C).

Electrical Rating:

8 A @ 120/240 VAC res., 30 VDC. 1/2 hp @ 120 VAC and 1/4 hp @ 240 VAC ind.

Power Requirements:

12 to 240 VAC/DC.

Power Consumption:

2.8 Watts max.

Electric Connections:

1/2" NPT conduit opening, screw termination and removable terminal block.

Process Connection:

See Catalog Page.

Mounting Orientation:

Vertical or horizontal.

Set Point Adjustment:

Trips when product touches probe. Cut or extend probe to length of desired trip point. Can be cut as short a 1" and can be extended by welding on to probe. (Minimum length will be effected by material being sensed.)

Time Delay:

Adjustable, 0 to 60 s.

Spark/Static Protection:

10 MEG Ohm dissipation resistance with spark gap. Surge current to 100A max.

Sensitivity:

8 selectable settings, 1, 2, 4, 6, 8, 10, 14, 20 pF (at 30 pF nominal free capacitance).

Compliance:

cULus.

Features

• Automatic Calibration: No need to turn calibration pots, just push the calibration button. The CLS2 even has an external magnet to activate the calibration without having to open the enclosure.
• Universal Power Supply: One model works from 12 to 240 VAC/DC without any jumpers or settings.
• Coat Guard: Unit is not affected by sticky, dusty, or clingy materials that coat or build up on the probe preventing false alarms.
• Failsafe Setting: Output switches can be set for Normally Open or Normally Closed condition on loss of power.
• Status Indication: Ultra high brightness external red LED switch status indicator, and internal indicators for power, sensor, and switch status that can be seen externally with window cap option (external LED on weatherproof model only).
• Time Delay: Prevent false alarms from material splashing, agitation, etc.
• Removable Terminals: Removable terminal block snaps in and out enabling easy wiring outside of the enclosure.
• No Moving Parts: Permitting for no jams, no wear, nothing to break, and no maintenance.
• Impulse RF: Admittance measurement combined with an active guard, provides excellent level measurement and stability while being insensitive to material buildup.
• Immune To: External RF sources like walkie-talkies and cell phones as well as minimal interference with radio communication or other electronic systems.
• Can Be Used For: Liquid interface applications to detect the level of two immiscible liquids that have different dielectric constants such as oil and water.
• Wetted Materials: PVDF and 316 SS assure great chemical compatibility and meet food grade requirements.
