About Sensors

Our sensors consist of models that are generally designed for long-term installation under adverse environmental conditions. Most of the sensors listed on our web site measure environmental and water resources parameters, but our dataloggers are not limited to measuring environmental sensors. Sensors used in industrial applications such as strain gages, accelerometers, hydraulic pressure transducers, etc. are also available, either through our applications engineers or from a third party.

Our dataloggers have many channel types and programmable inputs, enabling them to measure most commercially available sensors. Sensors that output voltage, pulse, SDI-12, RS-232, or 4-20 mA signals can be read using the datalogger's analog (single-ended and differential), pulse counter, SDI-12, RS-232, continuous analog output, digital I/O, anti-aliasing filter, and switched excitation channels.
