Nexisense HG808-K Temperature & Humidity Transmitter — Ideal Sensor for Harsh Environment Measurement
1. Facing Challenges: Pain Points in Harsh Environment Temperature & Humidity Measurement
1.1 Complexity & Challenges of Industrial Environments
In modern industrial and scientific research fields, many core processes occur in areas with extremely harsh environmental conditions. These “harsh environments” refer not only to extreme temperature or humidity but also to the superposition of multiple challenges:
Extreme temperature: High temperature (e.g., above 150°C) or ultra-low temperature.
High humidity & condensation: Steam and high humidity cause sensor condensation or dewing, instantly invalidating measurement data.
Pollution & corrosion: Oil/gas, dust, chemical corrosive gases (e.g., acid/alkali vapor) erode sensitive components.
Electromagnetic interference: Complex industrial site electromagnetic environment (e.g., frequency converters, high-power motors) severely affects signal transmission.
Traditional temperature & humidity transmitters are often helpless in facing these challenges, resulting in reduced accuracy, shortened lifespan, or even complete failure. Therefore, a transmitter capable of maintaining high precision and stability under all-round harsh conditions has become an urgent industry need.
1.2 Positioning of Nexisense HG808-K Series
The Nexisense HG808-K series temperature & humidity transmitter is designed specifically to address the above pain points. With its unique technical integration and material selection, it provides an ideal and reliable solution for precise temperature & humidity monitoring in various extreme environments.
2. In-Depth Technical Core Analysis: Robust Design Ensures Precision
The HG808-K series stands out due to its triple innovation in core components, structural materials, and intelligent functions.
2.1 High-Precision Ultra-High Temperature Resistant Sensing Element & Wide Range
Core Guarantee: The HG808-K series adopts high-precision ultra-high temperature resistant sensing elements. This is the cornerstone of achieving precise measurement, ensuring extremely high sensitivity and stability within wide temperature range of -40 to +190°C and humidity range of 0–100% RH.
Performance Manifestation: After more than 1 month of long-term precise calibration simulation in industrial extreme environments, it ensures high precision and strong stability of data measurement within the wide range, effectively reducing measurement errors and data drift.
2.2 316L Stainless Steel Probe: Resists Corrosion & Pollution
The transmitter’s “antenna” — the probe — is the vanguard directly facing harsh environments. HG808-K uses 316L stainless steel material for the probe.
Corrosion Resistance: 316L stainless steel is widely used in chemical, pharmaceutical, and marine environments due to its excellent corrosion resistance (especially to chlorides and acid/alkali vapors), effectively resisting chemical corrosive substance attack.
Protection & Mechanical Strength: Mechanical strength and waterproof/dustproof performance provided by 316L material, combined with customizable metal ventilation hood, enable continuous and reliable protection of internal sensitive components in oil/gas dust, high-pressure steam, and other harsh conditions.
2.3 Intelligent Probe Heating Function: Solves High Humidity Condensation Problem
Probe heating function is the “killer feature” of HG808-K series in dealing with high humidity environment challenges.
Anti-Condensation: In high humidity, low temperature, or rapid temperature change environments, water vapor easily condenses into dew on probe surface, instantly distorting measurement results. By heating the probe, surface temperature can be slightly raised above dew point, effectively removing water vapor condensation or dewing, ensuring humidity data reliability.
Self-Cleaning: In environments with high chemical or cleaner concentration, heating function can also assist in removing compound effects on probe, playing a certain “self-cleaning” role, further ensuring temperature & humidity data accuracy.
Convenient Operation: Users can directly control heating anti-condensation and other functions through display screen interface, with user-friendly design that automatically turns off after 10 minutes to avoid unnecessary energy consumption.
2.4 Powerful Anti-Interference & Transmission Capability
Anti-Interference Design: Transmitter adopts professional sensor anti-interference design, effectively shielding complex electromagnetic environment influence, ensuring signal purity.
Stable Transmission: Uses 8-core cable for data transmission, improving signal stability.
Multiple Signal Outputs: Transmitter can simultaneously output digital and analog signals, convenient for user access to different control or acquisition systems. Digital output (e.g., RS485) can simultaneously read dew point, humidity, temperature, and PPM values, providing users with more comprehensive environmental parameters.
