AXONModel J2D -Contactless Strain Gauge Telemetry System

SHARE

AXON J2D is a compact telemetry system designed for the simultaneous and contactless transmission of two independent strain gauge signals, catering to high-demand environments. It incorporates a unique contactless and wear-free design that ensures consistent and high accuracy under harsh operational conditions. The system operates up to temperatures of +125 °C, which is subject to confirmation, and features an inductive power supply that enhances its reliability and longevity. The AXON J2D includes a rotor unit that captures and digitizes dual strain gauge signals and a stator unit that inductively powers the rotor while receiving the measurement data. Additionally, it includes a control unit that handles power supply management and outputs two analog measurement signals. The system's compact design and focus on analog outputs make it an ideal choice for high-precision industrial applications where durability and accuracy are crucial.

Product Description

The AXON J2D telemetry system extends the capabilities of the J1DB by simultaneously capturing and transmitting two strain gauge channels. It is ideal for applications where two strain measurement points (e.g., bending and torsion) need to be monitored simultaneously on a rotating shaft. It offers the same robustness, contactless operation, and high accuracy as the proven AXON systems.
