Note on performance specifications:
"F.S." means maximum setting value of
transmitter output. "K" means cell constant.
YOKOGAWA provides conductivity sensors
which cell constant are 0.1 to 10 cm -1 .
The following tolerance is added to above
performance.
mA output tolerance : ± 0.02 mA of
"4 - 20 mA"
Step response: 90 % (< 2 decades) in 7
seconds
B. Ambient operating temperature
: -10 to +55 °C (-10 to 130 ºF)
C. Storage temperature
: -30 to +70 °C (-20 to 160 ºF)
D. Humidity
: 10 to 90% RH non-condensing
E. Housing
: Cast aluminium case with chemically resist-
ant coating, cover with flexible polycarbonate
window. Case color is off-white (Equivalent
to Munsell 2.5Y8.4/1.2) and cover is
Deepsea Moss green (Equivalent to Munsell
0.6GY3.1/2.0). Cable entry is via two PG13.5
nylon glands. Weather resistant to IP65 and
NEMA 4X standards. Pipe wall or panel mount-
ing, using optional hardware.
F. Data protection
: EEPROM for configuration and logbook
G. Automatic safeguard
: Return to measuring mode when no key-
stroke is made for 10 min.
H. Operation protection
: 3-digit programmable password.
I. EMC Conformity standards
