The Model CR is a rotating paddle style level control that can indicate the presence (or absence) of dry bulk material within a bin or hopper. The unit can be equipped with either 1, 2, or 3 heavy duty microswitches to control a variety of functions or alarms.
The Model CR is designed to provide an indication of material level within a hopper or bin without ever opening up the vessel.
Technical Specifications:• The housing is cast aluminum, with optional epoxy or polyester powder coatings available. These coatings will provide protection against corrosion that is equal or greater than cast iron. • The unit is designed with a field adjustable time delay. • The unit is mounted on the vessel using the mounting plate or by use of a 1-1/4" NPT half coupling. • General purpose (weatherproof) units and explosion-proof units have (1) 3/4" NPT conduit opening. • The units have a dry, unpowered microswitch rated for 20A @ 120 VAC, 240 VAC, or 480VAC. • The operating temperature range is -40ºF (-40ºC) to 150ºF (65ºC). • The general-purpose units are rated NEMA 4/4X weatherproof and corrosion-resistant, and explosionproof units are rated NEMA 7/9 for dust ignitionproof and vapor explosion proof. • The general-purpose controls are IP65 compliant. • Most models are UL listed and CSA certified
