The Valeport miniTIDE is a small Tide Recorder, designed for short-term underwater deployments, ideal for academic studies.
Fitted with a 0.01% temperature compensated piezo-resistive cell, the miniTIDE will record high accuracy pressure data for a period of one month at a 10-minute sampling interval, using a single alkaline C cell. It is available with a choice of pressure ranges, and with either 500m acetal or 6000m titanium housings.
The miniTIDE is fitted with a novel temperature compensated piezo-resistive pressure transducer that offers levels of performance previously only available from costly resonant quartz transducers.
Temperature compensated piezo-resistive
10, 30, 50, 100, 300 or 600 Bar
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 regular time 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.
The instrument 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:
Up to 200m cable, direct to serial port
Up to 1000m cable
4800 - 460800
8 data, 1 stop, No parity, No flow control
The miniTIDE is fitted with a solid state non-volatile Flash memory, capable of storing over 30 million lines of data.
