Here are the key features of the SOR V1 Dual Hi-Lo Pressure Switch:

Dual independent set points: Two discrete sensing assemblies allow for separate high and low pressure actuation, ideal for alarm or shutdown systems.

Wide adjustable range: Covers from 30 in Hg VAC to 4000 psi (1 bar VAC to 275 bar), making it suitable for a broad range of applications.

Fine-resolution calibration: Each set point can be precisely adjusted using a calibrated scale, with no interaction between the two.

Weatherproof housing: Designed for non-hazardous environments, offering durability and protection against the elements.

SIL-certified: Complies with IEC 61508 for use in SIL1 and SIL2 safety instrumented systems.

Field adjustable: Easy to configure on-site without special tools.

SPDT or DPDT switch options: Flexible electrical configurations to match system requirements.

Long service life: Static “O” ring piston design minimizes wear and enhances repeatability.

Frequently Asked Questions – SOR V1 Dual Hi-Lo Pressure Switch

1. What is the SOR V1 Dual Hi-Lo Pressure Switch used for? 

It’s designed to monitor both high and low pressure thresholds in a single device. Commonly used in alarm and shutdown systems, it ensures safety by triggering actions when pressure goes above or below set limits.

2. Can I adjust both set points independently? 

Yes. The V1 features two discrete sensing assemblies, allowing independent fine-tuning of high and low pressure set points without interaction.

3. What is the pressure range? 

It covers a wide span from 30 in Hg VAC to 4000 psi (1 bar VAC to 275 bar), making it suitable for vacuum and high-pressure applications.

4. Is the dead band adjustable? 

Absolutely. The V1 offers a wide, adjustable dead band, ideal for applications requiring separation between actuation and deactuation points.

5. Is it suitable for hazardous environments? 

No. The V1 is a weatherproof model, best suited for non-hazardous locations. For hazardous areas, consider the explosion-proof version.

6. What certifications does it carry? 

It’s certified for SIL1 and SIL2 (IEC 61508), and also carries CSA and UL recognition, ensuring compliance with safety and reliability standards.

7. What kind of electrical outputs are available? 

You can choose between SPDT or DPDT switch types, depending on your system’s wiring and logic requirements.

8. What materials are used for wetted parts? 

Multiple material options are available to ensure chemical compatibility with your process media.

9. How is it mounted? 

It can be mounted via the process connection or using panel/bulkhead mounting. Ensure a flat surface to avoid torsional stress on the housing.

10. What’s the warranty period? 

The V1 comes with a 3-year warranty from the date of manufacture.
