Ex-HK320C flameproof weighing instrument

Ex-HK320C flameproof weighing instrument

It is specially developed for weighing and control of dangerous chemical occasions. It can be used for filling, quantitative control and material level indication of dangerous chemical products, and can transmit the weighing signal of dangerous area to the automatic control system of safe area by analog or digital communication. It integrates on-site display and remote transmission. It is suitable for weighing control applications in dangerous gas environment.

The analog weight transmitter series is a product launched by our company for the industrial control field (or other applications that require analog output)
