    Overview

    The SUCH industrial-grade online dew point transmitter is designed for compressed air systems to monitor trace moisture in real time, helping improve drying system stability and prevent equipment corrosion, pneumatic failures, and quality issues caused by excessive moisture.With a -60°C to +90°C measurement range and ±2°C Td accuracy, it is suitable for refrigerated dryers, desiccant dryers, and industrial air systems. Featuring anti-condensation design, 16 bar pressure resistance, 150°C temperature tolerance, RS485 Modbus and analog outputs, it enables fast 1-second response and easy integration with PLC/SCADA systems. Ideal for compressed air monitoring, lithium battery, semiconductor, and precision manufacturing applications.

    Feature

    • Multiple Signal Outputs: Supports 4-20mA, 0-5V/0-10V, and RS485 outputs for flexible integration with PLC, SCADA, and control systems.
    • 4-Parameter Display: Simultaneously displays dew point, temperature, relative humidity (%RH), and moisture content (PPMv) for comprehensive process monitoring.
    • Wide Range & High Accuracy: Measures a wide dew point range of -60°C to +90°C with ±2°C Td accuracy. Operates reliably in ambient temperatures from -40°C to +90°C for stable industrial monitoring.
    • Smart Anti-Condensation Heating: Built-in heating function prevents sensor condensation. Heating can be controlled via the display and automatically turns off after 10 minutes to save energy.

    FAQ
    ❯

    Yes, it is built for harsh environments, supporting a high pressure resistance of up to 16 bar and withstanding extreme process temperatures up to 150°C.

    ❯

    It outputs RS485 digital signals and selectable 4-20mA/0-5V/0-10V analog signals simultaneously, enabling seamless control system integration with a fast 1-second response time.

    ❯

    No, the smart heating function activates via the screen to protect the sensor in high humidity and automatically turns off after 10 minutes, eliminating the need for manual monitoring.

    dew point transmitter does the job well
    I needed a sensor to keep an eye on moisture in my air system, and this one has worked as expected. The dew point transmitter is compact and does not require much maintenance after installation. I had to make a few small adjustments at the beginning, but the readings have stayed consistent. It is a practical choice for regular dew point monitoring.
