Intended Use
The High Pressure / Pirani Gauges of the type HPG400-SD
and -SP have been designed for vacuum measurement of
non-flammable gases and gas mixtures in a pressure range
of 2×10
-6
… 1 mbar. The control range of the gauge allows a
trend display from
<1 mbar (5×10
-2
mbar) ... 1000 mbar.

HPG400-SD DeviceNet
General Information
The HPG400-SD gauge has a fieldbus interface that
conforms to the DeviceNet standard (
→ [8]).
Via this interface, the following and further data are
exchanged in the standardized DeviceNet Protocol
(
→ [3], [8]):
• Pressure reading
• Pressure unit (mbar, Torr, Pa)
• Gauge adjustment
• Status and error messages
Two adjustable switching functions are integrated in the
gauge. The corresponding relay contacts are available at the
sensor cable connector.
The basic sensor and sensor electronics of the HPG400-SD
type are the same as in the standard HPG400 (
→ [1], [2]).

Supply Voltages
DANGER
The gauge may only be connected to power
supplies, instruments or control devices that
conform to the requirements of a grounded pro-
tective extra-low voltage (SELV-E according to
EN 61010). The connection to the gauge has to
be fused.
Supply voltage at the sensor
connector, Pin 8
+24 VDC (+20 … 28 V)
Power consumption
<16 W
DeviceNet operation requires an additional, separate
power supply.
Supply voltage at the DeviceNet
connector, Pin 2
+24 VDC (+11 … 25 V)
Power consumption
<2 W
The gauge is protected from reversed polarity of the supply
voltage.
