Sherborne Sensors LSW Series Weatherproof Servo Inclinometers

Product catalog summary

Overview
The Schaevitz® LSW Series is a DC-operated, gravity-referenced, weatherproof servo inclinometer designed for high precision and demanding all-weather applications. It features a stainless steel construction and a waterproof moulded cable system that is field replaceable.

Features

Weatherproof to IP67, ensuring dustproof and temporary water immersion protection.
High-level DC output signal proportional to the sine of the angle of tilt.
Available in angular ranges from ±3° to ±90°.
Rugged design capable of withstanding 1500g shock.

Applications

Geophysical and seismic studies such as bore-hole mapping and dam shifts.
Offshore, military, and civil engineering applications.

Environmental Characteristics

Operating temperature range: -18°C to 70°C.
Survival temperature range: -40°C to 70°C.
Shock survival: 1500g, 0.5msec, ½ sine.
Vibration endurance: 35g rms, 20 Hz to 2000 Hz sinusoidal.

Specifications by Range at 20°C

Excitation voltage: ±12 to ±18 Volts DC.
Current consumption: ±15 mA (nominal).
Full Range Output (FRO): ±5 Volts DC.
Non-linearity: 0.05% to 0.02% FRO depending on range.
Resolution: 0.2 to 4.0 arc seconds depending on range.
Thermal zero shift: 0.03% to 0.003% FRO/°C depending on range.

Ordering Information
Specify the model type with the appropriate range, e.g., LSW-14.5 for an inclinometer with a range of ±14.5°.
