RS485 Oxygen Temperature and Humidity Multi Parameter Sensor

Product Introduction:

The RS485 oxygen gas detection sensor is an intelligent monitoring terminal that integrates high-precision electrochemical sensing technology and industrial grade bus communication capabilities. The product adopts imported first-line brand oxygen sensors as the core detection components. Through exclusive compensation algorithms and multi-stage standard gas calibration, it achieves measurement accuracy of up to ± 2% FS and repeatability of ≤ 1% within the range of 0-30% VOL. The response time is fast to within 10 seconds, and the annual stability is ≤ 5% of the signal value. The service life can reach more than 24 months, fully meeting the strict requirements of long-term continuous, stable, and reliable monitoring of oxygen concentration in industrial sites. Based on the standard RS485 interface and ModBus RTU communication protocol, this sensor can easily connect to PLC, DCS, configuration software, and various upper computer systems, supporting long-distance transmission up to 2000 meters and free networking of up to hundreds of nodes, greatly reducing deployment costs and construction complexity.

Core advantages:

• 1.Accurate and reliable gas sensing. The equipment is equipped with an original imported electrochemical sensing unit, coupled with a 32-bit microprocessor and high-precision data acquisition circuit, combined with full range temperature and humidity compensation and zero drift suppression technology (zero drift is only ± 0.3% VOL), to ensure that the output data remains true and stable in a wide range of working environments of -20~50 ℃ and 5~95% RH. Its 10 second fast response and 5-minute preheating design enable real-time and efficient on-site monitoring.
• 2.Flexible and powerful bus networking. The standard RS485 interface supports ModBus RTU protocol, and the device address and baud rate (adjustable from 1200~115200bps) can be flexibly modified through instructions. The bus can mount up to 254 nodes. Only one four core shielded wire is needed to complete power supply and communication, with simple wiring, especially suitable for large-scale scenarios such as chemical parks, underground pipe galleries, and warehouses that require multi-point control.
• 3.Integrated multi-dimensional monitoring of temperature and humidity (optional). This model supports three in one output of oxygen, temperature (-40~+80 ℃, accuracy ± 0.5 ℃), and humidity (0~100% RH, accuracy ± 3% RH). One machine can synchronously collect three key environmental parameters, greatly reducing equipment procurement and maintenance costs. You can also choose a single oxygen detection version according to actual needs.
• 4.Durable and sturdy on-site adaptability. The product adopts a wall mounted waterproof shell with high protection level, which can effectively prevent dust and splashes; Support 10-30V wide voltage DC power supply, suitable for various on-site power sources; Optional high-quality OLED display screen for real-time viewing of numerical values on-site. Thoughtful installation accessories and clear wiring labels make installation and debugging more efficient.
