Our Dew Point Sensors are designed to give accurate, stable, and quick readings to ensure your air and gas systems are operating effectively and free from potential contaminants.
Whether you are running a PSA Nitrogen Plant, PSA Medical Oxygen Plant, Compressed Air Dryer, or Gas Purification Unit, our Dew Point Sensors help maintain system safety and that your air systems are dry, protecting your equipment and your product.
What is a Dew Point Sensor?
A Dew Point Sensor measures the temperature at which moisture in air or gas will begin to condense, thereby indicating what is known as the dew point. Knowing this value will help in compressed air systems and gas generation units to prevent water vapor contamination, equipment corrosion, and degradations in performance.
Harsiddhi Air Solution’s Dew Point Sensors utilize the latest capacitive thin-film polymer sensing technology, which ensures increased stability and accuracy in harsh industrial conditions.
How the Dew Point Sensor Works
- Sampling: The dew point sensor receives a flow of compressed air or gas that fills the sensor chamber.
- Moisture Detection: The sensing element will react to changes in both the humidity level and temperature so it can ascertain what the dew point is.
- Signal Conversion: The sensor will convert the dew point measurement into electrical signals, either 4–20mA or RS-485.
- Output Display: The output is indicated on a digital readout or sent to a PLC or SCADA system.
- Continuous Monitoring: Continuous feedback allows the system to remain in the dry range desired.

FAQs – Dew Point Sensor
Q1: What is a dew point sensor for?
A: It is used to measure the moisture content in compressed air or gas systems to ensure dryness and reduce condensation.
Q2: How often should I calibrate the dew point sensor?
A: We recommend calibrating the sensor every 12 months, in order to ensure you are getting accurate readings. Our sensors can either be calibrated at the factory or in the field.
Q3: Is your dew point sensor capable of use in PSA systems?
A: Yes, our dew point sensors are widely used in PSA Nitrogen and Oxygen Plants to monitor drying of the compressed air and rest assured gas produced remains pure.
Q4: What dew point is suitable for compressed air?
A: Commonly between -40C to -70C for industrial applications, but depending on the specific requirement of the system.
Q5: Can the sensors be used for high pressure?
A: Yes, our dew point sensors support a reliable operation of up to 20 bar, which is suitable for most compressed air or gas systems.
Q6: Do you have a digital display option?
A: Yes, we have an optional digital or HMI display so you can view the dew point in real-time.
Q7: How does dew point monitoring save energy consumption?
A: Monitoring the dew point shall manage the optimized operation of your air dryer eliminating over drying. This reduces the load on the compressor and saves energy.
