Pressure Sensor

SPOTTER PLATFORM

Pressure Sensor

Add a rugged, piezoresistive subsurface pressure sensor to your Spotter Platform to monitor water level in real time.

Combine with Spotter’s built-in barometer to track tidal changes, measure precise water depths, and detect storm surge.

Deployment & Best Practices

Configuration Options
Ideal for moored coastal deployments with one Spotter or a network.Integrate up to two more devices (e.g. pressure/oxygen) per Smart Mooring (max 3 total).

Remote Configuration & Controls
Direct control via Spotter Dashboard, binary/ASCII commands, and Sofar remote support.

Maintenance and Calibration
Mount with sensor head (pressure port) pointing downward to prevent debris clogging. Rinse with fresh water after retrieval. Recalibrate annually to offset drift (±0.05% FS/year).
