Technical Features of Honeywell Pressure Switches
Honeywell pressure switches exhibit several key technical features that influence their performance and suitability for specific applications. These features often vary depending on the specific model and intended use case. For example, the pressure range, switching type, and connection method significantly impact the switch’s functionality. The choice of materials also affects durability and compatibility with different media.
| Feature | Description |
|---|---|
| Pressure Range | The minimum and maximum pressures at which the switch will operate reliably. This varies greatly by model. |
| Switching Type | Defines how the switch operates (e.g., SPST-NO, SPST-NC, SPDT). This determines the output signal. |
| Electrical Connection | Specifies the type of connection (e.g., screw terminals, connectors). This affects installation ease. |
| Sensor Type | The sensing element used (e.g., diaphragm, bourdon tube). Different types offer varying accuracy and durability. |
| Operating Temperature | The temperature range within which the switch functions correctly. This is crucial for environmental considerations. |
| Material | The materials used in construction (e.g., stainless steel, brass). This influences corrosion resistance. |
| Mounting Type | How the switch is attached (e.g., panel mount, inline). This impacts installation and space requirements. |
| Accuracy | A measure of the switch’s precision in detecting pressure changes. Higher accuracy is often needed for precise control. |
| Repeatability | The consistency of the switch’s response to repeated pressure changes. This is vital for reliable performance. |
| Hysteresis | The difference between the setpoint and the reset point. A lower hysteresis value indicates higher precision. |
Different Types of Honeywell Pressure Switches
Honeywell offers a wide array of pressure switch types, each designed for specific applications and pressure ranges. The selection criteria depend heavily on the operational requirements and environmental conditions. The choice between different series will depend on factors such as the required pressure range, accuracy, and environmental conditions.

FAQs
1. What is the difference between SPST-NO and SPST-NC pressure switches?
SPST-NO (Single-Pole, Single-Throw, Normally Open) switches close the circuit when the pressure reaches the setpoint. SPST-NC (Normally Closed) switches open the circuit at the setpoint.
2. How do I select the correct pressure range for my application?
The pressure range must encompass the expected minimum and maximum pressures in your system, with a safety margin. Consult Honeywell’s documentation or a specialist for guidance.
3. Are Honeywell pressure switches suitable for hazardous locations?
Yes, Honeywell offers pressure switches certified for hazardous locations, meeting relevant safety standards. Check product specifications for certifications.
4. What maintenance is required for Honeywell pressure switches?
Regular inspection for damage and proper functioning is recommended. Specific maintenance requirements vary by model and should be consulted in the relevant documentation.
5. Where can I purchase Honeywell pressure switches in China?
Honeywell pressure switches are available through various distributors in China. Online retailers like cn.element14.com and others, as well as local industrial suppliers, often stock them.
