Product details
Typical applications
SB series online single gas alarmWidely used in industries such as petroleum, chemical, metallurgy, refining, gas transmission and distribution, biomedicine, and water treatment
SB series online single gas alarmcharacteristic
Standard two-wire 4-20mA current signal output, compatible with current
There is an alarm control unit or DCS (Distributed Control System)
● Large screen backlit multi parameter LCD display, visually displaying gases
Concentration, type, unit, percentage, and working status, etc
● Plug and Play! Standard intelligent sensor
Replacing the sensor does not require on-site calibration, and the key parameters of the sensor are automatically identified
● Automatic recognition and on-site display of sensor faults, while outputting phase signals
Fault current signal
● Full range temperature digital automatic tracking compensation to ensure measurement accuracy
The standard three buttons on this machine enable single person and single point on-site maintenance
● PC intelligent user software realizes single person single point setting and maintenance
Standard PDA intelligent user software enables single person single point setting and maintenance
On site and remote maintenance settings do not affect the control unit
