SL Series
WATERPROOF
MANY CONFIGURATIONS AVAILABLE
FOR ALL TYPES OF SENSORS
The waterproof SL wireless module offers a variety of configurations to read and transmit data from any electrical and/or vibrating wire sensors.
The SL Series is a robust interface module designed to read data from installed sensors (electrical and/or vibrating wire) in a borehole. The module can be configured to meet your exact project specifications.
The PVC housing has been tested under water at pressures up to 3 bars. Its waterproof design is ideal for applications where extensometers, piezometers or in-place inclinometer sensors need to be read at a location completely flush with the surface. The battery pack is installed in an isolated housing at the bottom to allow easy access for battery replacement.
The SL module can also be used as a standalone logger. Typical application would be the installation of a datalogger in a manhole located on a roadway or runway. The in-road antenna would transmit the data to a base station located in a safe indoor or outdoor environment. The proposed antenna is waterproof, robust and resistant to many chemical products like oil or gasoline.
