Detailed information on the German MESA carburizing, nitriding, and dew point measurement control system:

Shenzhen Beituo acts as an agent for Germany's MESA carburizing control system, which includes oxygen probes or lambda probes+carbon controllers.
MESA oxygen probes are divided into direct insertion oxygen probes and sampling oxygen probes.
*The type is: direct insertion type (model: MF160.39.09.0), which directly inserts zirconia into the high-temperature measured gas to directly detect the oxygen content in the gas. This detection method is applied to the temperature range of 700-1050 ℃ in the tested atmosphere, using the high temperature of the tested atmosphere to reach the working temperature of zirconia without the need for an additional heater. High detection accuracy, fast response speed, and minimal maintenance. In addition, MESA adopts the most advanced connection method internationally, which is to weld zirconia and alumina tubes together, successfully solving the high-temperature sealing problem of ceramic materials and achieving excellent sealing performance.
The second type is: sampling style (model: MF060), which introduces the measured gas into the zirconia detection chamber (model MK1) through a guide tube. The detection room heats zirconia to the working temperature (above 750 ℃) through heating elements and outputs a signal. Its detection method is flexible, with a lifespan of up to 5-7 years. During maintenance, only the Lambda probe (L-Sonde) needs to be replaced, greatly saving costs and time. Moreover, MESA company has adopted the design concept of a cooling hood, breaking through the limitations of sensors on the temperature inside the furnace, allowing sensors to sample and measure high-temperature atmospheres ranging from 1200-2000 ℃. (Lambda probe can also be used for detecting oxygen content in boiler flue gas)

For the carburizing control system, MESA's newly developed intelligent heating power supply NTV44P has the following functions:,
1. It can be input as a Lambda signal or a conventional oxygen probe signal
2. The working temperature of the Lambda probe can be controlled at a fixed value
3. The voltage signal of the Lambda probe can be converted into an equivalent isolation signal of the zirconia probe
4. It can output four types: 0-1300mV or 0-10V or 0-20mA or 4-20mA
5. It can calculate the percentage of oxygen content or dew point
6. Different blowing modes can be selected
If you choose MESA's carbon controller (Carbo-M, Carbomat-M), you can directly calculate and control the carbon potential through Lambda signals, without the need to convert it into a regular oxygen probe signal (almost all other carbon controllers on the market can only control carbon through regular oxygen probe signals). It is possible to replace the original system with a Lambda probe (with a lifespan several times that of a regular oxygen probe), a heating power supply (NTV44P), and a MESA carbon controller (which directly calculates and controls carbon potential through Lambda signals). The MESA carbon controller calculates the carbon potential based on the residual oxygen or carbon dioxide content in the furnace gas, and can connect two probes simultaneously to accurately measure the carbon content in the atmosphere of the heat treatment furnace, greatly improving the quality of the heat-treated products. The range of carbon potential measurement includes 0... 1.5% C or 0... 15... 1.5% C or 0... 2% C, and the output signal is 0-1300mV. It can store 99 carbon potential and temperature setting programs; Can display and output various parameters; The corresponding valve can be automatically controlled and regulated to control and adjust the carburizing atmosphere according to the set carbon potential value C. The models of MESA carbon control instruments include Carbo-100 and Carbomat-M (used for carbon potential control), Carbo-M， (Used for both carbon potential and temperature control).

Shenzhen Beituo Agency GermanyMESA Carbon Potential Direct Measurement System FPG1.0
At present, all commonly used methods for calculating the carbon potential inside the furnace on the market are indirect measurements through oxygen probes, CO2 probes, dew point meters, etc. MESA's high-quality portable carbon analyzer FPG1.0 can directly measure the carbon potential inside the furnace and automatically and quickly display and record the carbon content in the furnace atmosphere.

Shenzhen Beituo Agency GermanyThe MESA nitriding control system includes: sampling hydrogen probe+heating power NT46+nitrogen controller.
The MESA hydrogen probe detects the hydrogen content in the measurement chamber through the tail end of the sampler probe. The detection data results are linearized by the intelligent power supply NT 46. This hydrogen probe is not easily affected by temperature, has high reliability, and is resistant to vibration, making it easy to replace. Its measurement range is 0... 80% H2 or 0... 20% H2. The power supply NT46 controls the temperature of different sensors (H2 or CO or CO2) in the measurement chamber and provides a high stable power supply voltage. The MESA nitrogen controller Nitromat-M is a single channel measurement and control system used for controlling the furnace atmosphere in nitriding or carbonitriding processes. The program control of temperature and hydrogen, as well as the program tracking of gases such as NH3 (ammonia), N2 (nitrogen), Endogas (endothermic atmosphere), CO2 (carbon dioxide), etc., can be used to control the nitriding or carbonitriding atmosphere inside the furnace. In addition, MESA provides software for data recording and storage: one is software that only records and stores temperature and nitrogen potential, and the other is software that can record and store all relevant process parameters and configure and program nitrogen controllers.

Shenzhen Beituo Agency GermanyMESA Dew Point Measurement and Control System：
For endothermic gas generators, MESA has an economical and practical dew point control system with a relatively long working life, consisting of the following parts: a Lambda probe with a measuring chamber, a heating power supply NTV44P ordinary type, and a dew point controller DGTP. (Alternatively, a Lambda probe with a measurement chamber and an intelligent heating power supply NTV44P high-end TP can be used to calculate dew point values based on Lambda signals and can be connected to any control device). Its cost is only equivalent to 60-70% of carbon control systems, and its working life is also longer than carbon control systems. In this application, since the Lambda probe is not directly installed in the pipeline but measures the gas entering the measurement chamber, there is no need for even blowing and cleaning. In addition, MESA also offers pointer and digital dew point detectors for selection.

Shenzhen Beituo Agency GermanyMESA gas analysis system
The newly developed portable gas analyzer G5 series by MESA can be configured with up to 6 different gas sensors, mainly used for online measurement of furnace atmosphere. It can achieve 8 analog outputs, 8 digital inputs/outputs, and can be optionally equipped with a serial port. Serial communication can be accomplished through network communication protocols such as TCP, Ethernet, or fieldbus. All analog and digital inputs/outputs can be manually set, including alarms, calibration, or pump shutdown. The device also has a manual or timed data recording function, which can be achieved through USB data transfer or built-in 16MB memory. If users purchase the random software MGAS Viewer, they can view, print, output, or manage the stored data. MGAS automatic zero calibration is effective for all gas components. There is also a "quick calibration" function that allows users to manually change the displayed gas concentration. MGAS G5 can also be configured with several protection functions, such as shutting down the equipment when the dew point value is too high or the process temperature is too low to ensure the working life of the equipment. The MGAS analyzer adopts the most advanced technology of non diffusive high-precision infrared gas sensors, which have high precision, good long-term heat resistance, and long-term reusability. According to different user needs, the MGAS G5 gas analyzer has multiple configuration models that can measure the following gas components separately or integrated: CO, CO2, H2, CH4 and temperature, and can calculate carbon potential and dew point based on the above measurement values.
