Solon's unique design allows many features to be combined to build a variety of switch functions. Since many of the components used are "off the shelf", a highly specialized switch can often be ordered and shipped the same day.

Types of Sensors
Pressure switches use sensors to determine changes in pressure. Pressure switches used for sensing fluid pressure contain sensors that deform or displace proportionally to the applied pressure of the system. Solon® Pressure Switches have three different sensors available:
Bellows sensing elements are used in pressure switches designed for sensing fluid pressure. Bellows pressure sensing assemblies use 316 stainless steel bodies and hydroformed bellows. The hydroformed bellow is welded into the body resulting in a compact, rugged, sensitive assembly. Life expectancy can vary depending on the installation from a minimum of 100,000 cycles to 10 million cycles or beyond. The adjustable pressure ranges reach up to 5,000 psi. Solon Manufacturing Co. uses a Helium Mass Spectrometer leak detection system for bellows type switches. This technology is used to test 100% of all bellow pressure sensing assemblies, ensuring no measurable leakage in the field.
Diaphragm actuated switches employ diaphragms for their sensing elements. They are extremely rugged and can be used on an optional range of media. A very sensitive unit can be built to withstand high overpressures and shock by fully supporting the diaphragm, and are capable of millions of cycles. Various diaphragm materials are available including, Buna-N, Viton, and Kalraz. PTFE protection for diaphragms is also an available option.
Piston actuated pressure switches are designed for hydraulic or gas service and constructed to withstand severe shock and vibration. The piston element employs a reinforced PTFE seal that is spring-energized. This results in a consistent performance over millions of cycles.
Choosing a Pressure SwitchPressure switches are critical in fluid or gas control. Depending on your application, you may require a base model with no environmental considerations. However, challenging or rugged conditions may dictate a more robust model that includes weather-tight or explosion-proof options. Your Solon Manufacturing Co. application engineer will be able to help you determine product suitability and select a model appropriate to your needs.
Performance Under PressureSolon Manufacturing Co. delivers confidence with every pressure switch product you receive. We are so committed to your satisfaction that we offer a 10-year guarantee on all pressure switch products*.
Intrinsic SafetyAll Solon pressure switches are suitable for use in intrinsically safe systems because they are considered “simple apparatus,” which are very low power or passive devices that will not cause ignition. Simple devices may be safely integrated into IS systems when combined with intrinsically safe barriers. Solon suggests specifying gold contacts, which ensures reliable contact when used with the very low voltages and currents that the intrinsically safe barriers use.
