BCP Pressure Switch
Brand: DanfossThe BCP type is a series of dedicated pressure switches for safety and pressure monitoring of steam and hot water boilers.
The BCP incorporates a single-pole changeover microswitch where the contact position depends on the pressure in the connection port and the range set value.
For installations, in which operation is particularly critical for safety reason, the use of fail-safe control is recommended.
Features- Available as high and low pressure limiters as well as pressure controllers
- Wide pressure range: from low pressure BCP1 with narrow differential to high pressure BCP7
- The fail-safe dual bellows enable premature cut-out when fault occurs
- DIN plug mounted on the top of control for easy electrical wiring
- Single-pole changeover switch (SPDT), switch + alarm
- Direct mounting on pressure connection or wall mounting by means of a bracket
- Versions with automatic and manual resets available
- Screw adjustments made on top of housing
- Manual reset for pressure limiters possible only by means of tools
- Safety Integrity Level: SIL 2 according to IEC 61508:2010
