Kinemetrics MBB-2

Salient Features

The MBB-2 is a compact, triaxial broadband seismometer engineered for high-performance seismic monitoring in a wide range of environments. Built into a durable, passivated stainless steel housing, the MBB-2 provides a velocity-sensitive output across a broad frequency passband from 120 seconds to 150 Hz. With a nominal sensitivity of 750 V·s/m and low self-noise, it is capable of capturing both small ground motions and large seismic events with precision.

Accelerometers

EPIC Accelerometers: Titan Accelerometer Features:

Strong-motion sensors are accelerometers, and are designed to measure the large amplitude, high-frequency seismic waves typical of large local earthquakes. These seismic waves result in the strong ground motion we feel during a large earthquake. Strong ground motion is often to blame for the structural damage that occurs during an earthquake. The data seismologists record with strong motion sensors is used to improve the design of earthquake resistant buildings and to understand earthquake-induced geologic hazards like liquefaction and landslides. The range of motions of interest for strong-motion applications includes accelerations from 0.001 to 2 g and frequencies from 0 to 100 Hz or more.

3-Channel Dataloggers

Quanterra Q330

Q330's are typically used for broadband standalone and telemetered real-time data recording. They have an external storage device (either hard drive or USB flash drive) and lend themselves for a variety of telemetered modes.

 

Reftek RT130

Q8 Datalogger

The Q8 is a 6 channel high resolution datalogger. It is low power and configurable for a wide range of applications and sensors. It is housed in a machined aluminum enclosure and is nearly waterproof.  It has an external accessible data store of 32GB.  It has built-in sensor controls, scheduled mass recentering, and calibration functions. The Q8 is programmed with a via a webpage interface through either ethernet or wifi.

Updating Firmware For RT130's

The following is the procedure to upgrade the firmware of a RT130. The upgrade is applied to the RT130 from a firmware file which is copied to CF card and inserted to the RT130 before it is powered on.   NOTE: For EPIC RT130 dataloggers, please contact us before changing the firmware, we may not support all versions.  Thank you.   2013-04-02: We are updating to RT130 firmware version 3.4.3.  This update will not be made in the field as it includes reprogramming chips from several boards.  Please contact us for further information.    
1.  Obtain a copy of the new firmware.  EPIC will supply this.
 

Data Downloading & Backups from Q330's

This page provides instructions for downloading Balers using the EzBaler program and reviewing the State of Health (SOH) data using PQL. EzBaler is the best option for downloading data from multiple Balers at one time. Known problems are: it will sometimes fail to connect to a Baler (just try again) and it will hang up if it encounters corrupted data.  These instructions are written specifically for use with a PASSCAL MacBook field computer, but in general apply to other platforms as well.

The data downloading is in two parts.  The first part is downloading the SOH data which contains the low sample rate seismic data and systems data to be used for doing field Quality Assurance (QA) for the station.  The second part is downloading all of the seismic data for archiving.
