Digital Pressure Module (DPM) - (Figure 1-2)
The sensing element in the DPM is constructed from a micro-machined silicon
diaphragm assembly bonded to a stainless steel or Hastelloy body. A Hastelloy
isolation diaphragm and silicone fluid isolates the sensing element from the
process media.
The sensor piezo-resistors, diffused into the surface of the silicon diaphragm,
produce a signal in response to applied pressure. The accuracy of the sensor
element is enhanced by measuring the residual errors over its operating
temperature and pressure range and applying digital compensation in the
transmitter electronics.
Electronics Module (Figure 1-2)
The electronics module uses microprocessor technology to give a compact
circuit with the minimum of components. The module produces an extremely
stable signal unaffected by changes in ambient temperature.
®
The HART communication module gives digital two-way communications. The
®
HART protocol gives easy access to the process data and makes it possible
to adjust the transmitter configuration from any point in the loop.
An optional LCD module shows the applied pressure value in two ways:
• as a % of calibrated span represented by a bar graph
• as a value in the applicable engineering units.
The LCD shows the Primary Variable (PV) value for the applied pressure. The
LCD value is not affected by the re-range facilities.
1.3 Identification Codes (Table 1-1)
Table 1-1 shows the identification codes for the transmitter. Before you install
the transmitter, use this table to make sure that the data on the transmitter is
correct.
