Is now a good time for your business to upgrade to higher-performance digital sensor hardware?
Jewell Instruments has officially expanded its Ruby MEMS sensor platform with the launch of new digital accelerometers and inclinometers. This hardware update, which is now available, replaces the legacy JDI, DMH, DML, DMS, and DKA series.
Why it matters
By unifying these disparate sensor lines under the digital Ruby platform, the company is simplifying its hardware stack for industrial applications. This transition facilitates easier integration through shared mounting configurations while providing standardized digital outputs.
The new sensors feature an IP67-rated enclosure and utilize internal temperature compensation to maintain accuracy. The hardware is tested to withstand a 180 g shock for 0.011 seconds and supports connectivity via DB9 or M12 interfaces.
The players
Jewell Instruments
A developer of inertial sensors and measurement instrumentation used in industrial, aerospace, and robotics applications.
Althen Sensors & Controls
A distributor and sensor solutions provider that manages the selection and procurement process for the new Ruby sensor line.
The details
The Ruby series utilizes MEMS (Micro-Electro-Mechanical Systems) technology, where microscopic mechanical elements are etched onto silicon to measure physical forces like acceleration or tilt. Each sensor includes internal compensation circuitry that adjusts readings based on real-time temperature data, preventing drift. The units are drop-in replacements for the older JDI series, meaning they share the same physical mounting footprint and dimensions.

The Tech Race
The rollout follows the release of the Analog Ruby MEMS sensors in 2025. This digital update positions the platform as a long-term successor to the legacy JDI series by consolidating multiple sensor lines into a single, standardized digital ecosystem.
Users can now source the Ruby digital sensors through Althen Sensors & Controls, utilizing the same mounting configurations found in the legacy JDI series. Each device ships with a calibration report and is backed by a three-year warranty.
The takeaway
The move to the digital Ruby platform signals a shift toward simplified sensor maintenance for industrial users. Engineers should monitor the platform's performance against the legacy JDI series benchmarks to confirm reliability in high-vibration environments.
