PF261 Titan Flush Diaphragm Medium Pressure Switch
Brand: Pyropress Engineering Company LimitedPF261 Titan Flush Diaphragm Medium Pressure Switch
Brand: Pyropress Engineering Company LimitedThis range incorporates a flush diaphragm and is suitable for settings up to 32 bar.
It has been designed for use on processes involving mediums of a high viscosity level or containing suspended solids which would otherwise clog conventional recessed diaphragm models.
Resistors can be incorporated for ‘end of line’ and short circuit monitoring.
