BATTERY HOUSING with INTELLIGENT BATTERY MONITOR – for autonomous monitoring
Our battery housings include a unique power and sensor management system for the sensor and battery but do not include the battery.
For batteries, we are working with Blue Robotics and have housings suitable to accept one or two of the Lithium-ion 14.8V, 15.6Ah or Lithium-ion 22.2V, 28Ah batteries.
Our battery housings:
– Depth Rating: 900m
– Dimensions: 480mm (l) x 120mm (d)
– Power Management System: built-in to allow a low current draw when not sampling, for optimal battery lifetimes
– Battery Voltage Monitor: to ensure the voltage stays above its recharge minimum
– Onboard SD Card: for quick data retrieval post-deployment. Just pop out the SD card and take the data straight from the unit, removing the need to download the data from the sensor
To find which battery pack is best suited to your deployment, please check the table below as a guide to show how long each battery pack will last under various sensor measurement frequencies.
| Continuous (23 secs) | every 15 mins | every 1 hr | every 2 hr | every 3 hr | every 4 hr | |
| BP14V8S | 7 days | 19 days | 77 days | 152 days | 226 days | 298 days |
| BP22V2S | 12 days | 35 days | 138 days | 274 days | 406 days | 535 days |
| BP14V8D | 13 days | 39 days | 154 days | 305 days | 452 days | 596 days |
| BP22V2D | 23 days | 70 days | 277 days | 547 days | 812 days | 1070 days |
DATA TRANSFER UNIT – for easy communication to/from your sensor
The Data Transfer Unit (DTU) allows easy access from the sensor to a USB of a computer.
There are two different models:
| Depth Rating | Function | |
|---|---|---|
| DTU | Non-Submersible | DTU |
| DTU-A | Non-Submersible | DTU and Analog out functions |
ANALOG SIGNAL UNIT – for Voltage or Current output
The Analog signal units allow for either a current or voltage analog output from the sensor.
The different models are:
| Depth Rating | Function | |
|---|---|---|
| DTU-A | Non-Submersible | DTU and Analog out functions – Current or Voltage out |
| ACU300 | 300m | Analog out functions – Current out |
| ACU1250 | 1250m | Analog out functions – Current out |
| AVU300 | 300m | Analog out functions – Voltage out |
| AVU1250 | 1250m | Analog out functions – Voltage out |
The units can be terminated via SubConn or pigtail
