Pressure switch
Type BCP
The 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
Approvals
yy Available as high and low pressure limiters as well as pressure controllers
yy Wide pressure range:
from low pressure BCP1 with narrow differential to high pressure BCP7
yy The fail-safe dual bellows enable premature cut-out when fault occurs
yy DIN plug mounted on the top of control for easy electrical wiring
yy Single-pole changeover switch (SPDT), switch + alarm
yy Direct mounting on pressure connection or wall mounting by means of a bracket
yy Versions with automatic and manual resets available
yy Screw adjustments made on top of housing
yy Manual reset for pressure limiters possible only by means of tools
yy Safety Integrity Level: SIL 2 according to IEC 61508:2010
