QB2000T modular sulfur dioxide detector SO2 detector manufacturer

QB2000T modular sulfur dioxide detector SO2 detector manufacturer(hereinafter referred to as detector) is a fixed instrument that can continuously detect the concentration of toxic and harmful gases in the working environment.

To detect gas concentration through natural diffusion, an imported electrochemical sensor with * sensitivity and excellent repeatability is used; Immediately activate the sound and light alarm signal or drive the exhaust system when the preset alarm point is exceeded; The standard 4-20mA signal can be directly connected to the factory DCS system or RS485 digital signal and connected to the factory upper computer; The instrument adopts embedded microcontroller technology, with simple operation, complete functions, high reliability, and reliable overall performance.

The detector has the characteristics of performance, stable and reliable operation, easy installation and maintenance, and complete measurement of gas types, which meets the requirements of industrial site safety monitoring for high reliability and stable operation of equipment and diversified measurement of gas types; It has been widely used in industries such as petroleum, chemical, metallurgy, refining, gas transmission and distribution, biomedicine, and water treatment.

1. Support the free combination of various modules, which can form gas detectors with different functions. A regular gas detector consists of a main control module and an intelligent sensor module. It can be optionally equipped with an RS485 communication module to provide isolated RS485 signal output. Inserting it into a LCD display module or digital display module will provide digital display, high and low light alarm, fault status indication, and infrared remote control functions

2. RS485 signal output with signal isolation, standard Modbus RTU communication protocol. Supports direct connection with Siemens PLC or domestic and foreign PLCs or acquisition modules without the need for an RS485 isolation module.

3. Support free switching between LCD display module and digital display module, fast hot plugging, plug and play.

4. The new gas detector adopts standard interfaces, and each module has interchangeability, making it easy and convenient to replace the sensor module.

5. The sensor module and detector have anti misoperation interfaces to prevent incorrect insertion. And the positioning plug can be easily aligned and inserted by gently spinning it.

6. The detector can replace sensors of the same type, as well as sensors of different gas types and sensor modules with different ranges, and the operation and recognition are automatically completed. Catalytic combustion sensors and electrochemical sensors can be easily replaced.

7. No calibration settings are required after inserting any sensor module. The detector automatically recognizes, reads factory calibration data and related settings, and runs immediately after self checking is completed.

8. By replacing the newly manufactured sensor module with the old detector, the detector can achieve the same detection and alarm accuracy as before, meeting the requirements for measurement and other testing.

9. Once the most easily damaged or expired sensors fail, customers can easily find and solve the problem themselves through the convenient replaceability of the integrated detector, avoiding delays and labor costs in on-site service.

10. Inventory sensor module and detector module components, produced in combination, greatly shorten production and delivery cycles under the same inventory level.
