5-2. Connecting to the sensor
Direct mounting
The SA11 can be installed directly on top of the YOKOGAWA labelled sensor by means
of the Variopin connection system. In this case the temperature limit of the device is
determined by the process temperature, limited from -30 up to +100°C / -22 up to +212°F
for power 2.7 to +4.5VDC, -30 up to +125°C / -22 up to +257°F for power supply
+4.5 to +5.5VDC.

CAUTION
Place the Variopin connectors securely to guarantee IP67.
Cable mounting
When there is less room to install the SA11 on top of the YOKOGAWA labelled sensor or
when the process conditions are higher than +100°C (for power 2.7 to +4.5VDC) or
+125ºC (for power 4.5 to +5.5VDC), an alternative mounting method is to install the
SA11 using the optional wall/pipe mounting hardware. The SA11 in this case is connected to
the sensor using the dedicated extension cable model WE10 with a fixed length of 3 meter.
The ambient temperature limit of the device has to be within -30 to +55°C.

CAUTION
Place the Variopin connectors securely to guarantee IP67.
NOTE
Use the correct Variopin cable. For correct measurement without loss of specification the
SA11-P1 must be used with WE10-H-D-003-V1, all other types must be used with WE10-
H-D-003-V2.
