Language
Earlier Alarm, Faster Fire-fighting, Less Loss.
Characteristics And Benefits:
Industry standard 4-20mA standard signal output.
Alarm light, fault light, running light prompt.
Have two relay outputs.
Independent sound and light alarm active output interface.
Use 128*64 high-definition dot matrix LCD screen, unique large character design, observe the output value is very clear.
Two relays can be designed for different alarm values, which is convenient for separate control for early warning and alarm.
Infrared remote control function, easy to operate from a long distance without opening the cover.
The displayed value and 4～20mA can be calibrated separately to improve the accuracy of the instrument.
Product Overview:
The intelligent gas detection transmitter is designed by digital and analog hybrid communication technology. The intelligent gas detection transmitter has excellent performance, high stability, communication and self-diagnosis functions, easy installation and maintenance. On-site safety monitoring requires high reliability of equipment. It is widely used in petroleum, chemical industry, metallurgy, refining, gas transmission and distribution, biochemical medicine and other industries. The instrument is compatible with control systems which can realize remote detection, control and alarm.
