Air Temperature, Humidity, Pressure sensor

An integrated sensor measures Air Temperature, Humidity, and Barometric Pressure, featuring RS485 Modbus RTU output, ensuring accurate environmental monitoring by measuring multiple factors concurrently.

ALT-TH110-P is a combined Air Temperature, Humidity, and Barometric Pressure sensor with RS485 Modbus RTU output represents a comprehensive and integrated solution for environmental monitoring applications. This multi-parameter approach allows for a holistic understanding of the ambient conditions.

 

The sensor body constructed from stainless steel (SS) material, featuring a stainless steel sintered porous filter, enhances the robustness, durability, and performance. These materials are chosen for their ability to withstand harsh environmental conditions, ensuring the sensor's stability and accuracy over an extended operational life. 

 

The sensor is designed to adhere to the stringent accuracy requirements outlined in the IEC 61724-1:2021 standard, achieving Class A accuracy. This ensures that the parameter measurements are of the highest precision, reliability, and optimizing overall system performance.

 

The sensor features an RS485 Modbus RTU output, allowing real-time data output suitable for integration into weather stations, HVAC systems, Building Management Systems (BMS), industrial processes, industrial automation systems and SCADA systems. The sensor can be used outdoors with a UV radiation shield (to be ordered separately) as well as indoors directly without radiation shield.

Product Features

The sensor conforms to the Class A accuracy standard of IEC61724-1:2021, guaranteeing precise measurement performance according to industry regulations.

Temperature sensor accuracy is ±0.1°C between +5°C to +60°C, while humidity sensor accuracy is ±1% RH within 5% to 80% RH.

The industry-standard RS485 Modbus RTU output streamlines integration, ensuring effortless compatibility and user-friendly operation across diverse industrial applications and systems.

The sensor's stainless steel (SS) body, featuring a porous sintered filter and IP65 rating, guarantees ruggedness and suitability for all weather conditions.

The sensor's versatility extends to both indoor and outdoor settings, with an optional UV radiation shield, making it the optimal choice for all applications.

An all-in-one sensor simplifies environmental monitoring by providing comprehensive data collection for various parameters within a single device.
