Diaphragm switches are ideal for applications demanding instrument class accuracy and where pressure pulsations are less than 25 cycles per minute. Available in various pressure ranges up to 150 psi, diaphragm switches are suitable for use in either positive pressure or vacuum applications. Single, and dual, and triple circuit models are available. Housed models (D1H & D2H) feature a durable, anodized aluminum enclosure with an integrated 1/2" NPT conduit connector, a tamper-resistant cover for the setpoint adjustment screws, and are rated to NEMA 4 as a standard. For applications requiring a highly accurate switch in a durable package, Barksdale's Diaphragm Pressure Switches are the ideal choice.Features:Stripped and housed versions availableHigh accuracyIdeal for pressure or vacuumEasy setpoint adjustmentNEMA 4 (Housed Models)Up to 3 setpoints available in one switchDiaphragm Seal Option AvailableApplications:Pump & compressor monitoringEngine monitoringMachine toolsHydraulic power unitsMedical equipmentWaste managementFood & beverageFactory automationMetal working State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
