Ueda Seisakusho OPL-650 Series Differential Pressure Switch
Manufacturer: Ueda Seisakusho Co., Ltd.
Model : OPL-650 series
Features
- The OPL-650 series is ideal for indoor locations that require dust-proofing and drip-proofing, and like the OPL-550 series, is widely used in industrial machinery, hydraulic filters, compressors, chemical plants, etc., along with industrial air and hydraulic control devices.
- The set value can be changed from the outside without removing the cover.
- A metal bellows is used for the pressure-receiving element.
- In addition, the tip of the operating lever has a quick action mechanism that uses the repulsive force of a spring, making this a differential pressure switch that operates accurately in conjunction with the sensitive action of a snap switch.
