Harsiddhi Air Solution specializes in providing advanced RH Sensors (Relative Humidity Sensors) with accurate and reliable humidity measurement capabilities for various industrial and environmental uses. Harsiddhi RH Sensors have been designed using leading-edge sensing technology, which allows accurate humidity and temperature measurement of compressed air systems, PSA gas plants, and industrial air treatment.
RH Sensors can assist in creating air quality control, gas purity, or process stability for consistent performance, energy efficiency, and protection of equipment.
What Is An RH Sensor?
RH Sensor (Relative Humidity Sensor) measures how much water vapor is contained in the air or gas mixture as compared to how much the air could hold at a specific temperature. RH Sensors are one of the primary components in air and gas systems where moisture is critical to process efficience and safety.
The RH Sensors made by Harsiddhi Air Solution are designed with capacitive and polymer-based technology, which provides fast responsiveness, stability over time, and high resistance to contaminants, making them ideal for industrial and medical environments.
How the RH Sensor Functions
- Moisture Detection: The polymer element of the sensor absorbs water vapor in direct correlation to the relative humidity of the surrounding gaseous environment.
- Signal Conversion: This change in capacitance is then transformed into an electrical signal proportional to the humidity level.
- Temperature Compensation: Integrated temperature sensors ensure accurate and stable readings under any changing environmental condition.
- Output Transmission: After processing, the signal is displayed locally, or transmitted to control systems such as PLC, SCADA, or HMI panels for monitoring and automation.
Characteristics of RH sensors
- High accuracy: ±1.5% RH typical accuracy providing reliable results.
- Fast response: Quickly detects changes in humidity for precise control.
- Rugged design: Works well in harsh industrial environments and continuous service.
- Dual measurement: Measures both relative humidity and temperature at the same time.
- Digital or analog output: 4–20mA, 0–10V, or RS-485 Modbus compatible.
- Easy calibration: Field calibratable for long term stability.
- Compact and light weight: Ideal for retrofitting into air dryers, and gas system.
- Wide operating range: For use in –40°C to +80°C and 0–100% RH environments.
