WHS_1000
Wireless Hydrophone Systems

Lotek Wireless Hydrophone Systems (WHS) represent a unique, hybrid technology that brings the flexibility of radio telemetry to acoustic applications. WHS systems are capable of detecting underwater acoustic signals and relaying those signals through the air, in real time via VHF transmission, to a radio telemetry receiver.

Some of the key features and benefits of the Wireless Hydrophone System:

• Real time monitoring
  
  
• No need for cable connections
  
  
• Ease of deployment
  
  
• Exceptional range performance
  
  
• Adaptive and manual gain control
  
  
• Field replaceable battery pack
  
  

As an integral component within your telemetry system, the SRX 400 receiver complements your Wireless Hydrophone System with respect to both performance and applications potential. Possibilities include use with:

• Coded transmitters
  Up to 210 uniquely identifiable codes can be assigned on a single frequency to significantly reduce scan cycle time.
  
  
• CART tags
  Combined acoustic radio transmitters optimize signal mode for water conditions based upon user specified time, depth, or conductivity set point.
  
  
• Remote control
  Download data and upload receiver settings via land line, cellular, radio modem or MSAT link.

WHS_1100  Single acoustic channel retransmission via VHF
Valid signals detected on a single acoustic channel are relayed in the VHF band. Permits precise temporal resolution typically required for studies that examine movement patterns of large numbers of solitary animals.

WHS_1200   Dual acoustic channel retransmission via VHF
Valid signals detected on two acoustic channels are multiplexed and relayed in the VHF band. Dual channel capability benefits applications that involve larger numbers of tagged animals and studies in which animals congregate in the same study area(s).

The temporal resolution of the WHS can be enhanced. Ask our application engineers for details.

Periodic design modifications may alter specifications.
It is recommended that specifications be confirmed when placing an order.
