1 DESCRIPTION
1.1 Introduction
The Druck RTX 1000H series is a process pressure transmitter that measures
the pressure of liquid, gas or vapour and gives an analogue 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.
The transmitter uses the HART®protocol to give digital two-way
communication. The HART®protocol gives easy access to the process data
and makes it possible to adjust the transmitter operation. For example: to make
accurate adjustments to the zero and span. There are also push-buttons and
switches on the electronics module to adjust the transmitter operation.
1.2 About 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.
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.

2.1 Pressure Ranges
The transmitter is supplied in one of the standard (zero based) ranges or it can
be calibrated to any acceptable intermediate span. Refer to Table 1-1.
The transmitter label shows the factory calibrated range and the maximum
working pressure (MWP). The upper range limit (URL) = MWP.

Range adjustment
Figure 2-1: Range limits
Figure 2-1 shows the limits for range adjustment. For example:
Span: The minimum span available for a 2 bar device is 0.02 bar (100:1
down-ranging).
Zero offset: A 2 bar (MWP) gauge device can give 4 to 20 mA in the range
-1 bar to 2 bar. For example: If the span is 0.02 bar, 4 to 20 mA is available
anywhere in the range up to a maximum zero offset of 1.98 bar (calibrated
range = 1.98 to 2 bar).
