Explosion proof oxygen content analyzer

Introduction to Explosion proof Oxygen Content Analyzer

The explosion-proof oxygen content analyzer consists of a converter and a detector (commonly known as an oxygen probe). On the core component of the detector, the zirconia concentration cell, nanomaterials and * * * production processes are used, and additives that inhibit electrode aging are added to the electrode coating. Greatly improved the accuracy and service life of zirconia measurement probes. The detector adopts a direct insertion probe structure, which does not require a sampling system and can timely reflect the combustion status inside the boiler. If used in conjunction with an automatic control device, it can effectively control the combustion status. The converter adopts intelligent design of single-chip microcontroller and Chinese character LCD display, making data display and function control more user-friendly; Can be connected to various types of DCS data access devices. Make the operation of the instrument simple and easy to master.

Explosion proof oxygen content analyzer has the following characteristics:

1. It has strong universality and can directly replace oxygen analyzers from other manufacturers.

2. Large screen blue background white text LCD display.

3. Full Chinese operation menu (English menu can be provided for export products).

4. The oxygen range can be freely set within 0.01-25.00% (* * range 0-5%).

5. The temperature is controlled by PID, with constant temperature points of 700 ℃ and 750 ℃ (can be selected on site).

6. Oxygen content upper and lower limit alarm indicators and temperature upper and lower limit alarm indicators can be set.

7. One click correction of background potential.

8. Standard gas can be used for online calibration.

The 4-20mA standard current output is optically isolated from the main circuit and can be directly transmitted to the DCS system.

10. Multiple fault information prompts.
