The SDT270 has two measurements channels for external sensors:
The first one is equipped with a black collar. It corresponds to the B choice on the display. The black collar
LEMO is reserved for ultrasonic and Mass Flow sensors.
The second one with a red collar. It corresponds to the R choice on the display. The Red collar LEMO connector
is reserved for accelerometers.
The connections for external sensors are LEMO connectors. They are a commonly used industrial connector, considered
for their reliability and their robustness. They have a sprung-loaded knurled barrel and mechanical polarisation to go
