产品描述
The PSW8 series has been discontinued. Please see the PSW-500 as a possible alternative or contact our Engineering department.
OMEGA’s new modular series general purpose compact
pressure switches, offer a proven design for
stationary or mobile hydraulic applications.
Applications include factory automation, balers,
compactors, overload controls, machine tools,
hydraulic power packs, railway, and marine
applications. PSW8 series is available in a wide
range of configurations. Low pressure ranges
feature a diaphragm pressure switch design.
Higher pressure ranges feature a compact piston
design. A SPDT micro switch will change state on
increasing pressure at your set-point, and will reset
when your pressure decreases back below the
set-point by the amount of the deadband.
SPECIFICATIONS Set-Point Repeatability: Diaphragm Models: ±2% typical Piston Models: ±1% typical Setpoint Adjustment: Upon delivery, set-point is in the middle of the adjustable range. Turn adjustment screw CW to increase, and CCW to decrease. Hysteresis/Deadband: Less than or equal to 15% of maximum adjustable range Contact Rating: 1 Amp: Gold-plated 0.1 A @ 125 Vac, 01.
