Truedyne DGF-I1 Density Sensor for Gases revolutionizes gas density measurement by enabling direct measurements within the gas line or tank. At its core lies a MEMS-based tuning fork oscillator. The surrounding metal housing is filled with the gas to be measured, and the oscillator’s natural frequency varies in response to changes in gas density. To account for temperature variations, an integrated platinum resistor precisely measures the local temperature.
With its compact dimensions of 31mm diameter and 63mm length, the DGF-I1 can be easily installed in even the most confined spaces. A threaded connection and filter safeguard the sensor from contamination. Measured values are transmitted to a higher-level system via an RS485 interface. The sensor’s rapid response time of 5 seconds allows for real-time density measurement directly within the process, eliminating the need for interruptions.
