What is the Specific Device Profile for a Vacuum Pressure Gauge - ETG.5003.2080

ETG.5003.2080 describes the network visible component of a semiconductor Vacuum Pressure Gauge (VPG).  This SDP identifies three different classes of vacuum pressure gauges. A Vacuum pressure single gauge device (VG) uses a singular pressure sensor. A combo device (CG) uses multiple pressure sensors but only the signal from one of these sensors is read at a time as the other sensors are either over-range (measured pressure is higher than the sensor can read) or under-range (measured pressure is lower than the sensor can read). This allows for higher precision measurements and a wider pressure range for the vacuum pressure gauge. The third class of vacuum pressure gauges is Multi Device (MG) which also consists of multiple pressure sensors but at least two of these sensors are reading the pressure at the same time while the rest are out of range. Again, this allows for larger pressure range and accuracy. Trip points are loaded into the object dictionary to determine which pressure sensors are active in certain pressure ranges.  

This SDP calls out specific hardware requirements with respect to power connection and labeling. It also has well defined object dictionary specifications such as objects for customer specified offset and gain. The PDO mapping specifications break down requirements for each class of vacuum pressure gauge as well.
