General Instruments Intelligent single crystal silicon pressure
/Differential pressure transmitter
The intelligent pressure/differential pressure transmitter utilizes a microprocessor at its core and supports a modular design, enhanced by advanced digital isolation technology. This provides the instrument with high anti-interference capability and stability. Additionally, the transmitter features a built-in temperature sensor for compensation, improving measurement accuracy, reducing temperature drift, and offering excellent long-term stability, high reliability, and robust self-diagnostic capabilities. The transmitter can also be easily calibrated, set, and configured by the user through a HART operator.
