Overview
Rugged TROLL Overview
The Rugged TROLL 100 and 200 instruments are designed to measure pressure, level,
and temperature in natural groundwater and surface water. They also can be used at
industrial sites, landfills, and other installations.
Both instruments have completely sealed housings that contain an absolute (non-
vented) pressure sensor, temperature sensor, real-time clock, microprocessor, lithium
battery, and internal memory.
The Rugged TROLL 100 is designed to hang by a backshell hanger from a suspension
wire. The Rugged TROLL 200 can utilize the backshell hanger or can connect to a
cable for easy top-of-well RS485 communications via RuggedReader Handheld PC or
laptop computer. Additionally, Rugged TROLL 200 cables with stripped-and-tinned
cable ends can communicate with data loggers, TROLL Link Telemetry Systems, or
PLC devices via RS485 or SDI-12.
Rugged BaroTROLL Overview
The Rugged BaroTROLL measures and logs barometric pressure and temperature in
air. This data is used to correct the Rugged TROLL 100 and 200 data by compensating
for barometric pressure effects during the course of a log.
