Chemical warehouse ammonia toxic gas leak detection and alarm device， The QB10N toxic gas detector adopts an imported catalytic combustion sensor, which has good sensitivity and excellent repeatability; LCD or LED digital displays suitable for factory applications display the concentration value of leaked gas in real time, and immediately activate the sound and light alarm signal or drive the exhaust system when the preset alarm point is exceeded; The international standard 4-20mA signal can be directly connected to the factory DCS system, and the RS485 digital signal is connected to the factory upper computer; The instrument adopts embedded microcontroller technology, with simple operation, complete functions, high reliability, and reliable overall performance.

The QB10N toxic gas detector consists of a cast aluminum housing, a stainless steel sensor breathing apparatus, a sensor module, a display module, a main control module, a digital communication module, a dust cover, and a calibration cover.

Standard three wire 4-20mA current signal output, compatible with existing alarm control units or DCS (Distributed Control System)

◆ LED on-site display suitable for factory applications (optional LCD display)

◆ Automatic recognition and on-site display of sensor faults, while outputting corresponding fault current signals

Standard three button implementation for single person single point on-site maintenance

On site two-level light alarm, relay output (external sound and light alarm or drive exhaust and other peripheral devices)

Main functions:

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, which can be optionally equipped with relay output and sound and light alarm output. Inserting an RS485 communication module provides isolated RS485 signal output. Inserting an LCD display module or a digital display module provides 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 easily damaged or expired sensors fail, customers can easily find and solve problems themselves through the convenient replaceability of integrated detectors, avoiding delays and labor costs in on-site services.

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

11. Automatic diagnosis range locking, automatic fault warning;

12. Replaceable modular sensors that can be remotely calibrated;

13. Adopting a 16 bit embedded microcontroller;

14. Automatic calibration function to reduce measurement errors;

15. Calibration operations require password verification to effectively prevent accidental operations;
