Note on performance specifications:
The specifications are expressed with sim-
ulated inputs, because the DO402G can be
used with many different sensors with their
unique characteristics.
The following tolerance is added to above
performance.
mA output tolerance : ± 0.02 mA of
"0/4 - 20 mA"
Digital display tolerance : +1 digit
C. Response time
0- 90% : 10 s
D. Ambient operating temperature
: -10 to +55 °C (14 to 131 ºF)
E. Storage temperature
: -30 to +70 °C (-22 to 158 ºF)
F. Humidity : 10 to 90% RH non-condensing
G. Housing
Case : Cast aluminium with chemically
resistant coating
Cover : flexible polycarbonate window.
Case color : off-white (munsell 2.5Y8.4/1.2)
Cover color : moss green. ( munsell
0.6GY3.1/2.0)
Cable entry : via six Pg13.5 nylon glands.
Cable terminals: for up to 2.5 mm 2 finished wires.
Protection : weather resistant to IP65
standards.
Mounting : Pipe, wall or panel, using
optional bracket.
H. Data protection
: Non volatile memory for
configuration and logbook, and
lithium battery for clock support.
I. Watchdog timer
: Checks microprocessor
J. Automatic safeguard
: Return to measuring mode
when no keystroke is made for
10 min.
K. Power interruption
: Less than 50 milliseconds no
effect.
L. Operation protection
: 3-digit programmable password.
M. Connection via cables:
The distance between the ensor and trans
mitter can be up to 50 m if the WTB10 junc
tion box is used. This junction box can
not be used for the DO70G, for which the
allowable maximum distance is10 m.
