Mini Hermet Pressure Switch
Brand: SOR Inc
The Mini Hermet Pressure Switch is a robust field-mounted instrument.
The pressure sensing assembly is similar to a conventional SOR type. The main difference is that the switching element assembly is hermetically sealed in an explosion proof steel capsule.
Switching elements are SPDT or DPDT.
This pressure switch is suitable for a variety of process applications in hazardous locations and hostile environments where stainless steel exterior parts are required and where space is limited.
Basic models with standard wetted parts are normally suitable for air, oil, water and non-corrosive process fluids.
Features- Robust Construction - High cycle rate tolerance, long life, not critical to vibration, protected internal hermetically sealed switching element capsule.
- Instrument Quality - High resolution of Set Points, high repeatability, narrow dead band, negligible temperature effect, high overrange and proof pressures.
- Explosion Proof Hermetically Sealed Switching Capsule - Isolates switching elements from corrosive, hostile and hazardous environments and virtually eliminates problems from corrosion.
- Field Adjustable Set Points - Full range adjustability without disconnecting electrical power while maintaining explosion proof integrity, self-locking adjustment, no charge for factory calibration.
- Cost Effective - Simple, fast installation without special tools, long service life. Periodic service or spare parts not required.
- Agency Listings/Certification - Select models with ATEX, CSA, INMETRO, Rostechnadzor (RTN), SAA, UL. Meets most code and customer requirements.
- Safety Certified to IEC 61508 (SIL) - SOR products are certified to IEC 61508 for non-redundant use in SIL1 and SIL2 Safety Instrumented Systems for most models.
- Built-In Quality - Rigid quality standards maintained from raw material to finished product.
