1DESCRIPTION
1.1Introduction
The GE Druck RTX 1000A series is a process pressure transmitter that measures
the pressure of liquid, gas or vapor and gives an analog output proportional to
the applied pressure. The transmitter is available in a compact and lightweight
metal housing with facilities for direct mounting to pipeline installations. The type
of housing is specified in the order.
To adjust the transmitter operation, there are push-buttons and switches on the
electronics module
1.2About the Electronics Housing (Figure 1-1)
The electronics housing contains a digital pressure module (DPM), electronics
module, connecting cables and the terminal block.

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.
An optional LCD shows a value proportional to the measured pressure. Unless
an alternative configuration is specified in the order, the factory configuration
shows the pressure value as a percentage of the calibrated span. To change the
configuration, refer to section 4.
1.3Identification 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.
