Dew Point Transmitter
This transmitter (sensor) measures dew point in the dry compressed air from -60 to +60 °C Td. It is designed for reliable and accurate analysis even in high pressure industrial processes. By installing the dew point sensor, people can monitor the dew point and maintain an optimal humidity condition. It is used to meet the needs for industrial applications, such as compressed air system, pharmaceutical industry, food processing facility, etc.
Dew Point Transmitter / Sensor
During coating process, dew point meter with automatic temperature compensation and manual periodic calibration is essential to analyze the ideal ambient conditions because moisture can affect the success of the surface coating. Obviously, dew point temperature plays an important role in many industrial processes. BDTH01-01 dew point transducer is equipped with both 4-20mA transmitter and RS485 (Modbus RTU) output. Its user-friendly design makes your installation and operation simple. There are several features that make this dew point meter useful and cost-effective. First of all, wide dew point ranges, covering an overall range from -60 °C to +60 °C, are available. Second, it provides you with multiple process connections. Third, its rugged stainless steel housing offers protection to IP65. Last but not least, it provides long-term stability and reliability at a competitive price.

Compressed air is often used in industrial applications for a diversity of purposes, such as drying, blowing, mixing, cleaning, etc. When it comes to monitoring compressed air, dew point sensor can be a critical role throughout the entire industrial process. Take food industry for example, compressed air has direct or indirect contact with products in the food supply chain and finished products. Products may be contaminated because of the moisture in compressed air. To prevent products from deteriorating, compressed air must be dry and clean. For the same reason, compressed air system need dry and clean air, too. When moisture gets into compressed air, it may contaminate the compressed air and cause damages, such as icing, rusting, wear parts, etc. Rust can lead to disintegration of materials, especially metals. If compressed air pipes are corroded, compressed air may leak. Also, having moisture in compressed air can have negative influence on process and product quality. So, selecting a dew point transmitter with suitable measuring range is necessary. Monitoring dew point not only can ensure the working life of your machinery and the quality of final product, but prevent your products from being damaged.
