Plug & unplug a sensor
The SDT270 has two measurements channels for external
sensors:
The first one is equipped with a black collar. This
connector is meant for the black TankTest sensor
(emerged sensor) It corresponds to the “TTB2” choice
on the display.
The second one is equipped with a red collar. This connector is meant for the red TankTest
sensor (immersed sensor) It corresponds to the “TTR2” choice on the display.
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 only in one way round.
