PLX Boost/Vacuum Sensor Module

PLX Devices


SM-Vac/Boost accurately measures the vacuum pressure and boost pressure of any intake manifold. This is ideal for turbo and supercharged applications with monitoring the intake pressure is vital. Up to 32 SM-Vac/Boost modules can be daisy chained together in the iMFD system. SM-Vac/Boost can also be used as a stand alone unit capable of interfacing with 3rd party hardware. All Sensor Modules are housed in high quality extruded aluminum designed to operate even in the most extreme conditions. In addition, all SM modules offer outstanding digital accuracy, response and resolution which far exceeds that of a standard gauge.
