Product Datasheet (pdf 906 KB) Inclinometer Selection Tool SUBSEA-2-30-RS485 – Underwater Dual Axis Inclinometer, ±30°, RS485 Interface

The SUBSEA-2 series inclinometers are specifically designed for installation on underwater structures or 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. 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.
