Product Datasheet (pdf 906 KB) Inclinometer Selection Tool SUBSEA-2-05-RS485M – Marine Dual Axis Inclinometer, ±5°, RS485 ModBus

The SUBSEA-2 series inclinometers are specifically designed for installation on underwater structures or marine equipment & are rated for use up to 500m below sea level. Each unit is fitted with an industry standard male SubConn Micro connector. They are a range of high performance dual axis tilt sensors for measurement of angle in both pitch and roll axes while submerged in sea water or during marine and splash-heavy applications. These devices are available with standard measurement range options of ±5°, ±15°, ±30° & ±45. They utilise a very high performance MEMS sensor which exhibits low long term drift. RS232 or RS485 interface options are available with our standard communication protocol, we also offer a multi drop RS485 interface with ModBus communication protocol. They are CE & RoHS certified, & are manufactured, calibrated and tested in our UK factory to guarantee performance to the stated specification.
