Sherborne Sensors T700 Series Inclinometers

Product catalog summary

Introduction
The Sherborne Sensors’ T700 series are solid-state inclinometers designed to measure inclination proportional to the sine of the angle in single or dual axes. Utilizing MEM technology, these devices offer excellent shock resistance due to positive mechanical stops. The -0101 version includes a temperature sensor for individual characterization over its operational temperature range, allowing for high accuracy by minimizing errors related to zero offset, sensitivity, linearity, and thermal shifts.

Design and Specifications
The T700 series operates from an unregulated DC power source and is housed in a robust aluminum alloy casing with an integral shielded cable. The cable can optionally be fitted with an electrical connector. Key specifications include:

Full Scale Acceleration: ±30° or ±90°
Signal Output: Analog
Full Scale Output: ±1.000 ± 0.020 Volts (±30°), ±2.000 ± 0.040 Volts (±90°)
Zero Offset Voltage: 2.5 ± 0.1 Volts

Insulation Resistance: > 100 MΩ @ 25 volts DC

Additional Specifications for -0101 Version
After error correction, the -0101 version offers:

Accuracy X-Axis: < ± 1 Milliradian
Accuracy Y-Axis: < ± 1 Milliradian
Temperature Output: 1 µA / kelvin

The characteristic error correction equation is provided for each unit, allowing precise angle calculations.

Self-Test Feature
The T700 series includes a self-test feature. By applying 5 volts to the self-test connection, the output changes by approximately 4 volts, verifying sensor functionality.

The inclinometer utilises MEM technology and has positive mechanical stops confering excellent shock resistance. The -0101 version incorporates a temperature sensor enabling each sensor to be indivually characterised over its operational temperature range. A data sheet containing the characteristic output equation is supplied with each sensor enabling errors due to zero offset, sensitivity error, linearity, thermal zero shift and thermal sensitivity shift to be minimised. By entering the equation coefficents into the host operating software, cost-effective high accuracy acceleration sensing may be achieved. Designed for operation from an unregulated DC power source, the T700 is packaged in a robust aluminium alloy housing with an integral shielded cable connection; the shield is connected to the sensor case. The cable may, as an option, be fitted with an electrical connector.
