Pressure Switch Selection: 5 Critical Steps to Choosing the Right Product in Industrial Systems
1. Set the Operating Pressure Range Correctly
When selecting a pressure switch, the first thing to consider is the minimum and maximum pressure values of your system.
- Choosing a product with too narrow a range → constant triggering errors
- Choosing a product with too wide a range → loss of sensitivity
Ideal choice: models operating within 20–80% of your system pressure.
2. Consider the Type of Fluid
The type of fluid used (water, steam, gas, chemical liquids, etc.) directly affects product selection.
Examples:
- Steam systems → require high temperature resistance
- Chemical fluids → require stainless steel or special coatings
Incorrect material selection means corrosion and failure in a short time.
3. Mechanical or Electronic?
Pressure switches are divided into two main types:
Mechanical switches
- More cost-effective
- Durable
- Ideal for simple systems
Electronic switches
- Higher precision
- Digital control
- Compatible with automation systems
In industrial automation, electronic solutions are generally preferred.
4. Do Not Ignore Environmental Conditions
The operating environment plays a critical role in selection:
- Dusty environments → IP protection is important
- Humid environments → stainless steel body
- Explosive environments → ATEX certification
Incorrect selection = safety risk.
5. Brand and Reliability
In industrial equipment, brand choice directly affects performance. Reliable manufacturers provide:
- Longer service life
- More stable operation
- Lower maintenance costs
Brands such as Fantini Cosmi and Pakkens are commonly preferred in this field.
Conclusion: Right Choice = Fewer Failures + Higher Efficiency
Although pressure switch selection may seem like a small detail, it is a critical decision that directly affects system performance.
With the right product selection:
- Failure rates decrease
- Energy efficiency increases
- Operating costs are reduced
