Ueda Seisakusho PU64W(GA10) Series Pressure Switch With Pressure Gauge

Manufacturer: Ueda Seisakusho Co., Ltd.
Model : PU64W(GA10) series
Features
- The PU64W(GA10) series is an outdoor waterproof pressure switch equipped with a φ60 mm sealed pressure gauge.
- The pressure setting value can be easily checked at a glance using the two pointers displayed on the dial plate of the switch body.
- In addition, the pressure setting and ON-OFF pressure differential adjustments can be performed freely and quickly using two adjustment screws while checking the pressure gauge on-site.
- The pressure switch body uses aluminum die-cast construction. The main unit has a protection rating equivalent to IP65 (IEC529), and the pressure gauge has a rating equivalent to IP54 (IEC529).
- Conventionally, the pressure gauge and pressure switch required separate piping systems. Integrating them into one simplifies installation, reduces working time, and eliminates unnecessary piping components.
- When adjusting the pressure setting of the switch, simply glancing down allows to easily check the pressure value and smoothly adjust the settings.
- Enables pressure value monitoring on-site.

- The previously separated piping can now be neatly consolidated, simplifying operations.
