• HydroTest software
• Hydrophone Test Cable

The  ARS series servo controllers are universal controllers, which can flexible be integrated with numerous components like motors and drives. Due to an automised initial operation the servo controllers will be fast and easy optimised for the corresponding drive solution. The drives are suited for various application areas due to universal interfaces e. g. encoder analysis and fieldbus connections:

• Digital control engineering, highly dynamic, exact, drift-free
• Devices for single-phase supply with 230VAC and three-phase direct connection to the 400 VAC mains available
• Wide voltage range, also applicable for US systems
• Compact design, directly side-by-side mounted
• Integrated supply and brake unit
• Integrated line and motor filter

The Wireless Trigger Box (WTB) system is designed to operate with any Seismic Recording system and remote trigger unit. The WTB system requires at least two complete units: one WTB transmits trigger signal to all remote units and remote WTB units are typically connected to the Seismic Recording system.

Each WTB unit consists of a VHF radio with 3 selectable frequencies and Radio Trigger Module (RTM) for the trigger units synchronizing.

The standard WTB unit has been designed to operate with the DAQlink II seismic acquisition units and a Hammer Switch. One Hammer Switch WTB can trigger multiple DAQlink units connected to remote WTB units.

The standard Wireless Trigger Box System includes the following:

• Wireless Trigger Box for Hammer Switch
• Wireless Trigger Box for Seismic Recorder
• Cable to connect WTB to a Hammer Switch
• Cable to connect WTB to a DAQlink
• Cable to program WTB/RTM unit
• RTM Software CD
• Microphone/Speaker
• 12 V power cable

VLF surveying relies on radio signals that are broadcast from navigation stations around the world. The principle is that these signals are deflected in certain ways when they pass through conductive ore or water-filled vertical-to-sub-vertial fractures in the earth. By monitoring these deflections, the position and, potentially, size of the target can be determined.
