Compact Dual Axis PWM Output Inclinometer - H4PD1-22

Model H4PD1-22 provides dual axis inclination sensing in a rugged environmentally protected housing. This unit incorporates a MEMS (Micro-Electro-Mechanical Systems) sensing element referenced to gravity with integrated temperature compensation over the industrial operating range of 40 to +85C. The digital Pulse Width Modulated (PWM) output is linear with respect to the input angle directly.

Small dimensions and footprint make it easy for mounting to a horizontal plane, well suited for equipment with limited space requirements.

The H4PD has applications in leveling and tilt/slope monitoring; platform leveling equipment; material handling/process control equipment; aerial, scissor and boom lifts; cranes; and Derricks lift equipment/vehicles.
