Sherborne Sensors T435 Series Servo Inclinometers

Product catalog summary

Overview
The Schaevitz® T435 Series is a high precision, DC-operated, gravity-referenced servo inclinometer designed for applications where space is limited, such as down-hole logging. It is compact, measuring only 40.6mm in height and less than 37mm in diameter, and can be stacked for simultaneous X and Y measurements.

Features

Fully self-contained system requiring only a DC power source and a readout or control device.
Provides a high-level DC output signal proportional to the sine of the tilt angle.
Available in ranges from ±3° to ±90°.
Extremely rugged, capable of withstanding 1500g shock.
Stackable design for multi-axis measurements.

Applications

Geophysical, seismic, and civil engineering studies such as bore-hole mapping and dam monitoring.
Ideal for environments where space is constrained.
