About Dwyer 1620 Series Single and Dual Pressure Switches

Dwyer 1620 Series Single and Dual Pressure Switches

High Reliability, Repetitive Accuracy within +1%

On the Series 1620 Single and Dual Pressure Switch our old faithful switch design is still best where highest precision combined with diaphragm sealed leak proof construction and mounting simplicity are required. Model 1626 and 1627 differential pressure switches are identical in design and construction except that Model 1626 has a single electric switch and Model 1627 has dual electric switches. Model 1627 can therefore provide dual control when required. It can be set to open or close two independent electrical circuits, each preset for its own actuation pressure. Both units have diaphragm sealed motion take outs providing maximum protection against leakage.

CAUTION: FOR USE ONLY WITH AIR OR COMPATIBLE GASES.

Versatile Application Across Industries

The Dwyer 1620 Series is designed to handle a broad spectrum of pressure control tasks for steam, oil, and gas systems. Its adaptability makes it suitable for HVAC, industrial process, and energy sectors. As a panel-mounted solution with a corrosion-resistant galvanized finish, it ensures both flexibility and durability in installation environments often found in Indian industry.

Accurate and Reliable Performance

With a fine scale range of .15-1.5" w.c., the 1620 Series ensures precise monitoring of low differential pressures. This accuracy is crucial for maintaining safety and operational efficiency in systems processing sensitive fluids. Whether used by manufacturers or traders, the robust design helps prevent unexpected downtime and extends the service life of pressure-sensitive equipment.

FAQ's of Dwyer 1620 Series Single and Dual Pressure Switches:

Q: How does the Dwyer 1620 Series switch monitor and control pressure in steam, oil, or gas systems?

A: The Dwyer 1620 Series utilizes highly sensitive internal mechanisms to detect changes in differential pressure within a range of .15-1.5" w.c. When the setpoint is reached, the switch activates or deactivates connected devices, allowing for precise control and safety in steam, oil, or gas applications.

Q: What are the benefits of the galvanized finish on the 1620 Series Pressure Switches?

A: A galvanized finish provides excellent resistance to corrosion and wear, making these switches well-suited for harsh industrial environments. This ensures long-lasting performance and reduces maintenance frequency, benefiting both suppliers and end users.

Q: When should I choose the 1620 Series for my pressure monitoring needs?

A: The 1620 Series is ideal when you require accurate, low-pressure monitoring (from .15 up to 1.5" w.c.) for gases, steam, or oil. It's particularly effective in applications where reliability and swift response to pressure changes are vital for safety and process efficiency.

Q: Where can the Dwyer 1620 Series be installed within a system?

A: Designed for panel mounting, the 1620 Series is easily integrated into control panels and instrument enclosures. This mounting style ensures easy visibility and convenient access for adjustments and monitoring in various industrial setups across India.

Q: What is the process for setting the desired pressure range on these switches?

A: To set the pressure range, users adjust the externally accessible scale on the switch to the desired setpoint within .15-1.5" w.c. This user-friendly adjustment ensures precision and reduces installation time for manufacturers and system integrators.

Q: How can exporters and suppliers benefit from offering the Dwyer 1620 Series in India?

A: The 1620 Series is a trusted solution for managing low differential pressure in critical applications. By supplying these switches, exporters and suppliers cater to a diverse market, from chemical processing to HVAC systems, enhancing value to industrial customers seeking high-quality, durable components.
