Published:2013-8-27   Views:3402
Product introduction:
JC100T intelligent modular gas detector for natural gas diffusion concentration detection, using imported electrochemical sensors, catalytic combustion type sensor, infrared sensor or PID detector, with excellent sensitivity and good repeatability; suitable for factories and application of LCD LCD or LED digital display shows the concentration value of gas leakage, exceeds the preset alarm immediately start sound and light alarm signal or driving the exhaust system; the international standard 4-20mA signal can be connected directly to the factory DCS system, RS485 digital signal connected with the factory PC; instrument using micro control technology, embedded system has the advantages of simple operation, complete function, high reliability, the performance of the leading domestic level.
JC100T intelligent modular gas detector has excellent performance, stable and reliable operation, convenient installation and maintenance, the measurement of gas range and other characteristics, great to meet the industrial site safety monitoring of equipment reliability and stable operation and measurement of gas species diversified requirements; has been widely used in petroleum, chemical, metallurgical, petrochemical, gas distribution, biochemical medicine and water treatment and other industries.
Function characteristics:
The instrument uses ultra low power 16 bit embedded advanced micro controller
The user can set the high and low alarm
◆ important operation need password authentication, effectively prevent the misoperation
The standard three wire 4-20mA current signal output, compatible with the existing alarm control unit or DCS (distributed control system)
◆ RS485 isolated digital signal is connected with the upper machine factory
◆ LED digital tube display or LCD display
◆ sensor fault automatic detection and display, and output the corresponding fault current signal
◆ -40 ~ +70 ℃ digital automatic tracking compensation, to ensure the accuracy of
The standard three button to achieve single point field maintenance
The two stage light alarm, relay output (external sound light alarm or drive exhaust and peripheral equipment)
The detector can be replaced with the type of sensor, the sensor can also be changed with different gas species, different range sensor module, detector, automatic recognition, without the need for calibration
