2 to 3 Weeks
Dwyer L10-B-3-B LEVEL SWITCH BRASS 1 inch NPT MAX PRESS 250 PSIG
Wide media compatibility is assured with a choice of brass or stainless steel bodies and external tees; polypropylene or stainless steel floats. Two basic configurations are offered; with 1" NPT male threads for direct side mounting through a half coupling or with factory installed tee for external mounting. Features a hermetically sealed, magnetically actuated SPST REED switch which is encapsulated in a polypropylene housing. Units are quickly and easily adjusted for your choice of normally open or normally closed operation thanks to a unique patented design. Just loosen two screws and instantly slide the switch assembly to the action required. N.O. and N.C. markings are clearly visible. This feature also speeds switch replacement if damage occurs. Three types of floats are offered to accommodate liquids with specific gravities as low as 0.5; maximum pressures to 2000 psig (137.8 bar). Wire leads are 22 AWG X 18" (460 mm) and exit the switch assembly through 1/8" male NPT threads. These controls are UL recognized and CSA listed. Specifications
