Boiler Level Switches
Boiler level switches monitor the water level in a steam boiler, start and stop the feed pump and raise an alarm when the level rises or falls dangerously. They are core elements of safe boiler operation.
Conductivity devices with 4 electrodes combine high level alarm, pump stop, pump start and low level alarm in one body and are used up to 32 bar and 238 °C. The store range also includes capacitive boiler level electrodes in 500–2000 mm lengths.
Main Applications
- Steam boilers
- Hot water boilers
- Feed water tanks
- Condensate collection tanks

Material Options
| Part | Electrode device | Capacitive electrode |
|---|---|---|
| Sensing | 4 conductivity electrodes | Capacitive probe |
| Connection | Flanged or threaded | By model |
| Head | Finned cooling tube | By model |
| Length | Set by cutting | 500–2000 mm |
Which material? Boiler level switches do not replace low water safety; by regulation, independent low and high level alarm switches must also be fitted.
