PSW-563_PSW-571_PSW-572_PSW-573微型真空压力开关OMEGA

PSW-563_PSW-571_PSW-572_PSW-573微型真空压力开关OMEGA

能够感应非常低的正压或负压，可靠性和长寿命是这种设计的固有优势。非常容易的设定点调整：1）松开锁环，2）向左或向右转动接口，直到指针达到所需压力或范围标签上的真空，3）重新拧紧锁环，4）通过施加压力或真空来验证调整。有关声音警报和继电器模块，

xternal Pressure Scale and Pointer for Easy Setpoint Adjustments

5 Amp Model Switches With High Proof Pressures

1 Amp Gold-Plated Switches for TTL and Dry Contact Closures

Wetted Parts: Stainless Steel, Sealing Compound and or O-ring

Control Optional Audible Alarms or Relay Modules

Capable of sensing very low positive or negative pressures, reliability and long life are inherent advantages of this design. Extremely easy set point adjustment: 1) Loosen the lock ring, 2) Turn interface either left or right until pointer is at the desire pressure or vacuum on range label, 3) Retighten the lock ring, and 4) Verify the adjustment by applying pressure or vacuum. See Switch Accessories at omega.com for Audible Alarms and Relay Modules.
