Dew Point Sensors

Dew Point Sensors

Dew point control is a critically important task for many industries where precise measurement of moisture levels in air or other media is required. The dew point determines the temperature at which water vapor begins to condense, which can cause corrosion of metal structures, mold growth, disruption of technological processes, and other negative consequences. Dew point sensors allow timely detection of hazardous conditions and taking measures to eliminate them.

The "Izmerkon" website offers a wide range of dew point sensors available for purchase at manufacturer prices. All devices feature high measurement accuracy, reliability, and the ability to integrate into automated control systems. In this section, we will review the main types of sensors, their features, and areas of application.

Why are dew point sensors needed?

The dew point plays a key role in the following areas:

• Compressed air preparation systems: Dew point control prevents moisture condensation, which can cause corrosion, equipment damage, and deterioration of the final product quality.
• Pharmaceutical manufacturing: Dew point control is critically important to prevent moisture condensation that can lead to drug spoilage, microorganism growth, and sterility breaches.
• Microelectronics manufacturing: Humidity control in microelectronics production is critical, as even slight moisture can cause conductor oxidation, electromigration, and degradation of nanoscale elements, leading to chip failures.
• Ventilation and air conditioning systems: Dew point control helps prevent condensate formation on the walls of ventilation and air conditioning systems.
• Refrigerated chambers and warehouses: It is important to maintain a certain humidity level in refrigerated rooms to avoid product freezing or mold formation.
• Food production: Air humidity affects product quality, especially during raw material storage.
• IT infrastructure: In server rooms, humidity control is important to prevent electronics corrosion.
• Logistics and transportation: Maintaining optimal humidity during cargo transport is important to avoid product damage.

Dew point measuring instruments allow you to:

• Timely detect hazardous conditions.
• Prevent corrosion and mold growth.
• Ensure stability of technological processes.

How to Choose the Right Dew Point Sensor?

The choice depends on many factors. Here are the main criteria:

1. Measurement Range

Determined by operating conditions. For example, for supplying air to machines and equipment in assembly shops, a sensor with a measurement range around +3°Ctd is sufficient, while for compressed air used in pharmaceutical enterprises — up to -100°Ctd and beyond.

2. Accuracy

Especially important in laboratories, medical institutions, and when working with sensitive technological processes. For such tasks, it is better to choose sensors with an accuracy class of ±1°Ctd or better.

3. Output Signal

Digital (Modbus, RS-485) or analog (4–20 mA). The choice depends on the type of control system and data transmission method.

4. Environmental Conditions

It is necessary to consider the level of dust, presence of aggressive substances, vibrations, and pressure fluctuations. For such conditions, sealed housings and corrosion-resistant materials are provided.

5. Availability of Additional Functions

Alarms, self-diagnostics, wireless data transmission — all these increase ease of use and reliability of control.

6. Price and Maintenance Costs

It is important to consider not only the initial price but also costs for installation, calibration, and replacement. Budget models may require frequent maintenance, which will increase overall expenses.
