Compact, Low Cost Switch/Gage
Mini-Photohelic® Differential Pressure Switch/Gage combines the differential pressure gage with two SPDT switching set points. Designed to measure and control positive, negative, or differential pressures.
 
Features
	- 
	Gage reading unaffected by switch operation and will continue to read pressure even during power loss 
- 
	Visible switch status LED provides indication of set point switching state 
- 
	Compact design but with the power of larger devices can meet the same application specifications 
Product Applications
	- 
	Fume hoods 
- 
	Dust collection 
- 
	Pneumatic conveying 
- 
	Clean room
