Universal Breakout Box
This waterproof unit provides a connection and monitoring point for sensor input, power, sensor output, and interfaces to Güralp Handheld Control Units. It is compatible with all Güralp analogue broadband sensors. All input/output connectors are 26-pin and each connector has all inputs and outputs.
The Breakout Box is supplied with 5 m of cable and all the required connectors. The cable length and type can be customised.
Handheld Control Unit
The HCU connects to an instrument either directly or through the Breakout Box.
Two forms of HCU are available: one for CMG-3 weak-motion instruments, and one for all other Güralp sensors.
The meter displays the sensor velocity or mass position signals, and outputs them on banana jacks. Calibration signal input jacks and a CAL ENABLE switch are also provided.
The HCU is supplied with a short (1 − 2 m) cable to connect to the breakout box. A longer cable may optionally be supplied, depending on your requirements.
