Gems Sensors Series Flow Switch
Inline Flow Switch for Low Pressure Drop
Quick Specs...
- Flow Rate Settings: 0.50 GPM to 3.00 GPM
- Port Size: 1/2" NPT, 3/4" NPT, 1/2" Tube Compression Fitting
- Primary Construction Material: 316 Stainless Steel
- Setting Type: Fixed
Overview / Design Principle:
The FS-480 large-body inline flow switch delivers ample flow rates with minimal pressure drop. 25% larger than its FS-380 sibling, the FS-480 is ideal for processes that push more fluid through their systems and demand low pressure drops. Designed to accommodate the Semiconductor Industry's move to larger 300 mm wafer and cross-over equipment, this switch is also perfect for critical medical equipment applications. A glass-reinforced PPS piston and forged 316 stainless steel body make this sensor rugged enough for high pressure lubrication and cooling systems as well. This simple, yet meticulously perfected design provides the reliability required in critical applications while allowing for much lower pressure drop rates than other available switches.
