Manufacturer: Ueda Seisakusho Co., Ltd.
Model : DPU72W series

Features

The DPU72W series is a waterproof differential pressure switch for indoor and outdoor installation.
The switch body is made of aluminum die-casting, making it lightweight and sturdy.
The standard controlled fluids are air, water, and oil (fluid temperatures of -10 to 90°C), etc.
Stainless steel bellows are also available as an option for corrosive fluids, hot water, etc.
Depending on the type of fluid, careful consideration is required, so please consult our sales staff for details.
