The miniTIDE is a small Tide Recorder, designed for short term underwater deployments. Fitted with a 0.01% temperature compensated piezo-resistive cell, the miniTIDE will record high accuracy pressure data for a period of 1 month at a 10 minute sampling interval, using a single alkaline C cell. This makes it ideal for use in short term projects or for academic studies. Available with a choice of pressure ranges, and with either 500m acetal or 6000m titanuim housings.

The miniTIDE is fitted with a novel temperature compensated piezo-resistive pressure transducer that offers levels of performance previoulsy only available from costly resonant quartz trandsducers. |
| Pressure: |
Range : 10, 30, 100, 300 or 600 Bar |
| Resoluton : 0.001% range |
Accuracy : ±0.01% range |
| |
| Data Acquisition: |
| The miniTIDE features a selection of pre-programmed sampling patterns, allowing the device to monitor (and average) pressure readings for a number of seconds at a regular times intervals, e.g. 40 seconds sampling every 10 minutes. |
| Alternatively, the instrument may be set to output data at a fixed sample rate of 1 or 2 Hz, for continuous monitoring applications. |
| |
Communications: |
| The instruments will operate autonomously, with setup and data extraction performed by direct communications with PC before and after deployment. It also operates in real time, with a choice of communication protocols fitted as standard and selected by pin choice on the output connector. |
