Level Indicator for Slurries

For medium slurries, particulate and corrosive chemical solutions, the L-30 Liquid Level Switch from Harwil Corp can dependably control pumps, alarms, or solenoid valves. Made from Noryl, the L-30N, for mildly corrosive slurries and Fortron, the L-30 CR, for use with more caustic chemicals, these adaptable L-30 Level Switches can be mounted horizontally or vertically. Switching capacity is 15 amp, 120/240 VAC, or Gold Contact “Dry” circuits for microprocessor connection. Flexible, elastomeric seals prevent particle contamination and a “Filter Boot” can be added for extra protection. The L-30 mounts in 1 ¼” NPT fillings and is simple to maintain and test in the field. Another option is to add Harwil Corp’s Intrinsically Safe Relay making the L-30 useful in hazardous applications.
