101/121 Differential Pressure Switch
Brand: Cameron
101/121 differential pressure switches are rugged, field-mounted instruments that incorporate a flexible modular design providing cost effective sensing solutions.
The two-piece piston design allows for complete differential pressure reversal without damage.
101/121 differential pressure switches are suited for low-to-high differential pressure, fluid power or process applications where high and varying static pressures, high overrange, proof, shock pressure or cycle rates are expected.
Features- Modular Design: Wide range of electrical enclosures available
- Robust Construction: Rugged, high cycle rate tolerance, long life, not critical to vibration, high overrange and proof pressures, withstands full Hi and Lo side pressure reversals, excellent corrosion resistance to hostile environments
- Instrument Quality: High repeatability, narrow dead band, negligible temperature effect and static influence.
- Wetted Parts: Wide selection of materials
- Field Adjustable:
- Excellent resolution of Set Points, adjustment, no special tools required
- No-charge factory calibration
- Agency Listings/Certification
- Select models with ATEX, CSA, UL
- Meets most code and customer requirements
- Delivery
- Routine shipments 7 to 10 working days
- Emergency shipments via air same day
- Service: Factory service engineers and area factory representatives provide effective and prompt worldwide service
- 3 years warranty from date of manufacture
