Nexisense High-Temperature Temperature and Humidity Transmitter: Powerful Tool for High-Temperature Scenario Monitoring, Full Analysis of Maintenance and Advantages
I. Pain Points in High-Temperature Scenario Monitoring, Nexisense Provides Professional Solutions
In many critical links of industrial production, such as steel smelting furnaces and kilns, tobacco high-temperature drying, and petrochemical flue gas emission monitoring, high-temperature environments are ubiquitous. In these scenarios, the stability of temperature and humidity parameters directly determines product quality, production safety, and process compliance—during precision ceramic firing, a temperature difference of just a few degrees Celsius may cause finished products to crack; in the tobacco drying stage, humidity deviation directly affects taste and shelf life; during chemical reaction processes, loss of temperature and humidity control may even trigger safety hazards.
However, ordinary temperature and humidity monitoring equipment often faces issues such as component aging, precision drift, and sharply reduced service life in continuous high-temperature environments, making it difficult to meet long-term stable monitoring needs. Nexisense, deeply engaged in the industrial monitoring field, has specifically developed the 808-H series high-temperature temperature and humidity transmitter, which, with its excellent high-temperature resistance and precise monitoring capabilities, has become an ideal monitoring partner for high-temperature scenarios. This article will comprehensively analyze the value of this equipment from dimensions such as maintenance, core advantages, and application scenarios, providing practical reference for enterprise selection and operation & maintenance.

III. Maintenance Techniques for Nexisense Transmitter in High-Temperature Scenarios
The particularity of high-temperature environments accelerates equipment wear, and scientific maintenance is the key to extending the service life of the Nexisense 808-H series transmitter and ensuring monitoring accuracy. Combined with high-temperature scenario characteristics, it is recommended to standardize operation and maintenance from the following four dimensions:
(I) Regular Cleaning and Appearance Inspection, Building Basic Protection
In high-temperature scenarios, dust, oil stains, furnace slag, and other impurities easily adhere to the transmitter surface, especially blocking the sensing area of the 316L stainless steel probe, directly affecting temperature and humidity acquisition accuracy. Therefore, a regular cleaning mechanism should be established: Use clean, soft lint-free cloth to gently wipe the housing and probe, avoiding corrosive cleaning agents; after cleaning, focus on checking whether the appearance has damage, deformation, coating peeling, or corrosion traces, particularly whether the connection between the probe and housing is well sealed.
For example, in furnace and kiln operation scenarios, high-temperature dust and slag easily condense on the probe; if not cleaned weekly, it may cause temperature measurement deviation exceeding the allowable range; in petrochemical flue gas monitoring environments, sulfur-containing flue gas may corrode the equipment housing—upon discovering abnormalities, timely assess the impact on measurement performance, and replace seals or probe components if necessary.
(II) Standardized Calibration and Accuracy Testing, Ensuring Data Reliability
Continuous erosion in high-temperature environments can cause parameter drift in internal components of the transmitter, thereby affecting measurement accuracy. Therefore, detection and calibration must be strictly carried out according to the calibration cycle: Use professionally calibrated instruments certified by metrology, compare the transmitter's measured values with standard values in a standard temperature and humidity environment, and adjust internal parameters through the equipment's built-in calibration interface until precise measurement is restored.
It is routinely recommended to perform a comprehensive calibration every 6-12 months; if the equipment is in 24-hour continuous high-temperature operation (such as power plant boiler monitoring), shorten to every 3-6 months. Taking high-temperature oven baking applications as an example, precise calibration ensures the equipment strictly follows the preset temperature curve, avoiding uneven baking due to temperature deviation and ensuring product quality stability.
(III) Specialized Probe Protection and Heat Dissipation Optimization, Extending Core Lifespan
The probe is the core component for temperature and humidity acquisition and requires focused protection in high-temperature scenarios: On one hand, avoid mechanical damage such as collision or extrusion to the probe, and keep it away from direct high-temperature airflow impact areas to prevent erosion; on the other hand, the installation position should be chosen in areas with stable airflow that truly reflect environmental temperature and humidity, avoiding installation at equipment air outlets or local high-temperature dead corners.
In addition, heat dissipation conditions directly determine equipment service life: Leave at least 5cm of heat dissipation space during installation, avoiding close contact with other heat-generating equipment; for extreme scenarios exceeding 150°C, optionally install simple heat sinks or forced air cooling devices to prevent internal circuit damage due to overheating. In coke oven gas pipeline monitoring scenarios, reasonable planning of installation angle (45° with airflow) and adding heat dissipation sleeves can extend equipment service life by more than 30%.
(IV) Line Inspection and Connection Tightening, Ensuring Transmission Stability
High-temperature environments accelerate aging and embrittlement of line insulation layers, easily causing damage, short circuits, open circuits, etc., while vibration may loosen connection joints, affecting data transmission stability. Therefore, line status should be checked monthly: Inspect whether the insulation layer has cracking, discoloration, or hardening, focusing on whether terminals, plugs, and other connections are secure, with no oxidation or loosening traces.
Upon discovering line defects, promptly replace with high-temperature resistant dedicated cables (such as PTFE insulated cables); when connections are loose, use appropriate tools to tighten joints, avoiding excessive force that damages interfaces. In industrial automated high-temperature production lines, stable line connections are the foundation for real-time temperature and humidity data transmission, effectively reducing production downtime caused by data interruption and improving overall production efficiency.
IV. Advantages of Nexisense High-Temperature Transmitter Compared to Ordinary Equipment
Compared to ordinary temperature and humidity monitoring equipment, the Nexisense 808-H series high-temperature temperature and humidity transmitter has been fully optimized for high-temperature scenarios, with core advantages reflected in the following aspects:
(I) Excellent High-Temperature Resistance, Easily Handling Extreme Environments
Ordinary monitoring equipment mostly can only withstand temperatures below 80°C, easily suffering component burnout and precision failure in high-temperature scenarios. In contrast, the Nexisense 808-H series adopts ultra-high-temperature resistant sensing elements and 316L stainless steel probe, with temperature measurement range up to 190°C, stably adapting to conventional high-temperature environments of 80-185°C.
Taking steel smelting furnaces and kilns as an example, where furnace temperatures are maintained at 160-180°C for long periods, ordinary equipment may fail within 1-2 weeks, while the Nexisense transmitter can operate continuously and stably for months in this environment, continuously and precisely feeding back temperature changes, providing critical data for real-time smelting process control and ensuring steel product composition stability and mechanical properties.
(II) Precise Temperature and Humidity Measurement, Adapting to Complex High-Temperature and High-Humidity Scenarios
