The RDI provides single or dual axis inclination sensing in a rugged environmentally protected housing. This is a semi-custom unit where all subassemblies are stock but specific functions are customized. A modular design allows the customer to select the measurement range, output type, and temperature compensation that best suits the individual application. Standard input ranges ±10°, ±30° and ±70° are available for both single and dual axis models – these can be scaled to specific ranges (ie: ±45º) per axis. Special single axis ranges up to ±100° are available. Non-symmetrical (or scalable) ranges (ie: -10° to +90°) are available for applications that only tilt in one direction.
