Units are compensated for effects of temperature on both sensitivity and zero, and incorporate positive mechanical stops, conferring excellent shock resistance.

The Sherborne Sensors A640 series range is designed to operate from an unregulated DC power source and offers a high useable frequency response. An unfiltered output offering a usable frequency response up to 600 Hz and an additional 5Hz low pass filtered output is standard on all units. . Signal ground is isolated from power ground. Electrical termination is via a military-style, Bayonet lock connector. Units may be supplied with the output biased at 1 g, to offset the effect of gravity. Other model variations are available upon request.

Typical applications include data acquisition systems, crash recorders, fatigue life monitoring and prediction, road bed analysis, mass transit system monitoring and deceleration control, high-speed railway fault detection equipment monitoring, military and civil flight simulators, autopilots and low-frequency vibration monitoring.

Tilt sensors

New digital tilt indicators
Converts inclinometer output to display angle, with a resolution as low as to 0.001°

Sherborne Sensors has announced the launch of the DTI series, a family of 5-digit, programmable digital panel meters, offering improved tilt measurement system versatility and performance.

The DTI series is designed to take an output from any of their gravity referenced inclinometer, provide the necessary trigonometric conversions, and display the output as an angle, with a resolution down to 0.001°. For seamless interface with a data acquisition system, two supplementary outputs, an analog voltage output and a RS422/485 serial output, are supplied. The enclosure is manufactured from recyclable and flame retardant (VO) materials, with front panel conformance to IP65: NEMA 4.

Because of its versatility, the DTI Series can be effectively implemented into simple, measurement-only applications, as well as those requiring digital communications, alarms and mathematical functions. The powerful menu-driven software, also supplied, enables fast and flexible set-up from the front panel or via serial communications link. In addition, built-in, comprehensive alarm functions for the DTI Series makes them particularly suitable for monitoring, switching and control functions. The hysteresis facility prevents noisy signals from switching alarms erroneously, with high and low deviations facilitating control around a set point. On and off delay times can be set with individual alarms, configured as latching or non-latching, depending on user requirements.

The DTI Series is suitable for use with most of their gravity-referenced inclinometers, as well as other manufacturers' products. An integral 12 VDC power supply is intended to provide excitation voltage for MEMS- based inclinometers. Bi-polar voltage supplied inclinometers may be also powered via Sherborne Sensors XT-0102 or XT-0103 series power supply modules. For customer convenience, the DTI Series can also be supplied as a completely calibrated tilt monitoring system, including the inclinometer.
