LSR : Closed Loop Single Axis Servo Inclinometer, ±5V Out Features Single axis angle measuring Output fully conditioned offering a complete stand alone measurement system Ranges ±1° to ±90° Extremely rugged (withstands 1500g shock) Measurement resolution down to 0.1 arc seconds Options for voltage (±5V) or current (4-20mA) output. Solder pin outputs Stackable for X and Y dual axis measurements 100% Over-range ability 2 Year Warranty Applications Description The LSR series is a high precision closed loop gravity referenced servo inclinometer, it is designed for use where overall space is limited. The device incorporates a closed loop mechanism suspended in an oil damped chamber. The unit can be stacked to provide dual axis x and y measurements. Models are available in a wide variety of angle ranges and solder pin terminations are standard. There is also a 4-20mA output version available.

LSR : Closed Loop Single Axis Servo Inclinometer, ±5V Out Voltage Output Change With Angle As the LSR sensor is tilted the sensing element is subject to gravitational acceleration which exerts force on the proof mass. The proof mass is attached to a torquer mechanism in a closed loop configuration. A feedback current is applied to the torquer mechanism to maintain the mass in a positional equilibrium. The amount of feedback current is proportional to the acceleration (due to gravity) acting on the mass, and this current is converted to a voltage at the output stage. As such the voltage...
