General Instruments TT HART with Digital Indication
GIC is the leading TT HART with Digital Indication Manufacturer in India providing reliable solutions for accurate temperature measurement to process industry worldwide.
The smart transmitter is a hart temperature transmitter with high precision and high stability. It integrates most standard HART protocol commands and some custom commands. It is suitable for signal transmission of up to ten types of thermocouples and thermal resistors. The product uses 24 bits of independent ADI company Σ- △ analog sampling chip to ensure high accuracy of measurement; Perfect anti surge and anti-reverse connection design to avoid mis installation and mis operation in engineering application; Enhanced software security design, including independent watchdog, low-voltage monitoring reset, multi task scheduling optimization and other functions. All imported components are used to ensure long service life and stability. The button and HART communication line device can be used for configuration settings.
