Fixed silicon hydride gas detectors with high humidity resistance detailed introduction of the product The fixed gas detection transmitters produced by our company are widely used in industries such as metallurgy, petroleum, petrochemicals, chemical engineering, petrochemicals, ships, electric power, mines, and urban gas. With an explosion-proof design, they are equipped with imported sensors and original imported electronic components. The machines are assembled using surface mount technology on a strict dust-free assembly and debugging production line. It features a three-wire 4-20mA or four-wire RS485 standard signal output, enabling long-distance data transmission and seamless integration with DCS systems. The instrument is characterized by high sensitivity, rapid response, long service life, and short polarization time, ranking among the leading domestic products of the same kind.
Performance Advantages Advanced microprocessor technology, with good stability, strong anti-interference ability, and excellent resistance to poisoning. It has a three-wire 4-20mA analog output and 2 SPDT relay outputs (RS485 is optional). The standard three-wire current loop has high accuracy and no temperature drift throughout its lifetime. It can be adjusted on-site to adapt to unconventional hosts or DCS.
bit industrial-grade high-performance microprocessor technology, along with CMMI4 high-maturity software design.
Ultra-bright LED for on-site concentration display. Automatic fault identification and alarm. Alarm for gas concentration exceeding the limit at high levels.
A user-friendly menu operation mode, eliminating the need for users to remember complicated button-pressing patterns.
