The Smart Solo IGU-16HR 3C is a compact all-in-one 3-channel sensor & datalogger with onboard GPS timing, and a self-contained power supply. Similar to the FairfieldNodal ZLand 3C, it has been adopted by the academic community as a useful sensor for both active and short-term passive experiments.

The units require a pre-deployment plan to be filled out with the sample rate, gain, and minimum or linear phase specified. The units must be sent back to EPIC for data offload, unless the portable harvester system is requested for the experiment.

The FairfieldNodal ZLand 3C is a compact all-in-one 3-channel sensor & datalogger with onboard GPS timing, and a self contained power supply. Originally designed for use in large N industry deployments, it has been adopted by the academic community as a useful sensor for both active and short-term passive deployments.

Unlike other sensors & dataloggers at EPIC, use of the ZLand 3C requires a deployment plan to be filed in advance with EPIC for handheld unit pre-programming.  Likewise, the units must be sent back to EPIC for data offload.

The Power Box is a combination of enclosure, solar charge controller, and connectors which ensure the battery is charged and the instrumentation is powered. Below are some pictures of the EPIC power box (and below that is the old standard EPIC power box) . All the power boxes have a 12-15 amp load capacity and a Low Voltage Disconnect (LVD) to prevent damage to the battery. These boxes are designed to work with any nominal 12 volt solar panel and any deep cycle gel-cell lead acid battery.

Introduction

“Huddle”-testing sensors before field deployment is a key part of any seismic experiment.  Huddle-testing involves testing almost all components of the field station, for many stations, in parallel.  The number of stations that can be tested at one time is limited only by availability of personnel and lab space.

Huddle-testing potentially reduces crew time spent in the field, cost of the experiment, and the need to revisit sites.  Huddle-testing improves crew consistency and most importantly, the likelihood of successful station deployments and survival.
