Electricity-Contact Manometer
-
0.00 ~ 0.00/
1/ (Min. Order)
Key Features of an Electrical Contact Manometer:
✔ Pressure Sensing – Measures gas/liquid pressure (usually in psi, bar, kPa).
✔ Electrical Contacts – Built-in switches (mechanical or solid-state) that activate at set pressures.
✔ Adjustable Set Points – Allows customization of high/low pressure triggers.
✔ Output Types – Can be SPST (Single Pole Single Throw) or DPDT (Double Pole Double Throw) for different control needs.
✔ Materials – Often made with brass, stainless steel (SS), or phosphor bronze for durability.
Brass vs. Stainless Steel (SS) for Electrical Contact Manometers
| Factor | Brass | Stainless Steel (SS) |
|---|---|---|
| Corrosion Resistance | Good for air, water, oils | Excellent (handles harsh chemicals, seawater) |
| Durability | Moderate (softer metal) | High (strong, long-lasting) |
| Cost | Lower | Higher |
| Electrical Conductivity | Better (good for contacts) | Lower (but still functional) |
| Typical Use Cases | HVAC, compressed air, low-corrosion environments | Chemical plants, marine, food processing |
Recommended Applications:
-
Brass Contact Manometers: Best for compressed air systems, water pumps, and general industrial uses where corrosion is minimal.
-
SS Contact Manometers: Ideal for chemical processing, marine applications, and food-grade systems where rust resistance is critical.
