General Description
The MPS4264/EPx miniature pressure scanner
represents the forefront of pressure measurement
technology. It has been designed from the groundup with size, accuracy, and functionality in mind.  
It boasts 64 pressure channels, TCP/IP Ethernet
connectivity, and a wealth of other features.
A new valve was designed that fully isolates thesensors from purge pressure and provides longterm, maintenance free operation. Not only isthe valve design an improvement over legacy
products, but also introduces a new method ofvalve operation never before used in Scanivalve
products.

MPS4264/64EPx Ethernet
Pressure Scanner

The EPx version still maintains the same robustfeatures that are found in the MPS4264 seriesscanners. Communication protocols remained
unchanged. Precision Time Protocol is available
for time correlated data, and scan data can becollected via TCP, FTP, or UDP at scan rates up to2500Hz*. A TCU option is available for the MPS/EPx.

The EPx was designed to be used in applications
where a pneumatic supply for control pressure isinconvenient or unavailable. The NPx and CPx
variants of the MPS4264 require pneumatic control
pressure to change the valve state, where the EPx
utilizes an internal motor to change the valve state.
This electronic valve provides users with the abilityto change the valve state from measurement mode
to calibration/purge mode with a simple softwarecommand. An optical valve position sensor canalso be queried with a software command todetermine the valve position.
The power requirements and scanner footprint
are the main differences when comparing the EPx
to the typical CPx or NPx MPS4264 model. Theinternal motor that drives the valve requires a 1836VDC to operate the electric valve.
