Introduction:

QB2000 gas alarm control panel is a multi-point monitoring of the latest design with simple operation and it combines with any gas detectors to form an industrial gas detection system.

This control panel embeds micro processor as control unit, when the detected gas density in the air reaches or exceeds the pre-set value, the controller will give out audio-visual alarm immediately to remind you take safety precautions and alert the corresponding valve, exhauster and other equipment to avoid explosion, fire, toxic gases to protect the safety of life and treasures.

This system applies to metallurgy, petrol, petrifaction, chemistry, light industry, coking, municipal administration, gas, pharmaceutical, sewage dealing and many other special industry and field that need proofing for fire, explosion, and toxic gas leakage.

Characteristics:

High-performance sensor
128*64 dot matrix big screen liquid digital display
With English Instruction Manual and pictures easy to operate
Various gas detector together to fix
Display the detected gas density in distance
High sensitivity, and quick response
Automatic compensation for temperature -drift and time drift
The up and low alarm points of each channels can be set separately
8 channel 4-20mA signals output
RS485, RS232 communication port can upload data to computers & 4 Relay output and the relay setting is programmable

4-20mA analog output for direct communication to DCS system or RS485 ModBus RTU output optiona.
Relay output for connecting external device
LCD display screen(LED display screen optional)
Advantage: Sensor module(block) design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
When the sensor out of service or the sensor fails, the user can check and solve the problem by replacing spare modules,saving the time and cost.
The LCD display and LED display module can be interchanged, supporting swift hot swap,support plug and play functionality.
The sensor module and the connection interface in the detector have jack and plug prevent improper insertion.Just spin and press the plug gently,the plug can be inserted the jack.
The sensor module of the detector can be replaced by the same type module and the different gas sensor module,and different range sensor module. The detector can distinguish and operation itself.
Whatever the sensor module is chosen to replace the original one, there is no need to re-calibrate it. The detector automatically distinguishes the sensor module, reads the ex-factory calibration value and the related setting value and operates detecting when the self-inspection is done.
Password verification for repeat operation, avoid fault operations.
-40~+70 following compensation for accurate detecting.
Twp grade visual alarms on-site and Relay (connected with audible/visual alarms or drive exhaust device).
User-selectable alarm setpoint(s).

Mosi2 electrical heating element
MoSi2 electrical-heating element is a resistance generate-heating component made from MoSi2 or the basic material. It is used in high temperature under the oxidizing atmosphere, it looks like glass in its surface and forms a light SiO2 glass film which can protect the element not to be oxidized. So this kind of element has unique effect for resisting oxidization in the high temperature. It is used to the highest temperature up to 1800f¦ during oxidizing atmosphere. According to your request, our company can produce the products of Pole, "U", "W" and "U"-right angle shapes
