AXONModel J2DT -Strain Gauge and Thermocouple Signal Telemetry System

SHARE
The AXON J2DT is engineered to seamlessly combine a strain gauge signal with a thermocouple signal in a compact, contactless, and wear-free telemetry system suitable for demanding applications. With the ability to capture and digitize both strain gauge and temperature signals, it ensures precise measurement and reliable data transmission. The system comprises a rotor unit for capturing and digitizing signals, and a stator unit that inductively powers the rotor and receives the data. The J2DT operates up to a temperature of 125°C and features an inductive power supply along with integrated cold junction compensation. It provides separate analog outputs for strain gauge and temperature measurements. This system is designed for high-performance environments requiring accurate sensor data acquisition and offers variants tailored to specific requirements.
