S2IP measures and records the pressure and the tilt of immersed instruments such as the particle collectors or trawl panels.
The measurements of tilt are made along 2 perpendicular axes.
S2IP can have an autonomy in excess of one year depending on the settings and the sampling rate.
Tilt range : +/- 85°
Resolution : < 0.1° at 30°
Accuracy : +/-0.3° at +20° and -20°
Tilt sensor : Accelerometer +/-2g
Pressure sensor : Piezoresistive (case and diaphragm made of hastelloy)
Response time of sensors : 10 ms
300m Depth range (S2IP300) Accuracy : 0.9m, Resolution : < 0.15m
6000m Depth range (S2IP6000) Accuracy : 18m, Resolution : < 3m
Weight (in air) : 600g
Length : 235 mm
Diameter : 40 mm
Material : Titanium and ketron
Sampling rate : Programable from 0.05 s to 99 hrs
Programable starting : immediate, delayed, timed or set threshold (depth or tilt)
Memory capacity (*) : 1Mb (with data compression)
(*) the recording autonomy depends on the resolution and the sampling rate.
