Page 3: Introduction
The T1 and T1R temperature sensors are designed to provide trouble-free submersible operation when properly installed. The T1 (non-recording version) operates on an external (9 to 16 VDC) power supply and is ideal for use with many data loggers and SCADA systems. -

Page 30: Trouble Shooting
The single most important step in minimizing a ground loop is to tie all equipment (sensors, dataloggers, external power sources and any other associated equipment) to a single common grounding point. Seametrics recommends the following: (1) the sensor cable shield (the wrapped shield inside the cable) be attached to the power ground on the datalogger and (2) the grounding lug be connected via a 12 AWG or larger wire, to a grounding rod driven into the earth. -
