Ametek Crystal APMi [APMI-1KPSI] Intrinsically Safe Pressure Module, 1/4 NPT Male, 1000 psi, 3.3 ft (1m) Interface Cable Length.

The Crystal APMi intrinsically safe pressure modules, with integrated CPF female connections offer the functionality and flexibility to read up to 4 pressure inputs with a single HPC50 calibrator. In addition to the two installed modules in the HPC50 Series, two APMi pressure modules can be connected to the device. This provides the flexibility to either expand the range of the HPC50, view all four pressure readings at the same time, or to read two different differential pressures.
