S215 Dew Point Transmitters for Fridge Dryers (-20… +50 °C Td)
The SUTO S215 Dew Point Sensor provides reliable dew point monitoring in industrial applications, with long-term stability and high accuracy over the full range of -20 … +50 °C Td. Along with its compact design, this makes it the ideal solution for compressed air and gas dew point measurements in refrigeration dryers.
The plug-and-play dew point solution monitors the compressed air quality and purity according to the ISO 8573-1 standard. Meeting these requirements helps ensure fridge-dryer efficiency and reliability.
Output Signals for Great Flexibility
The dew point transmitter is available with 2-wire or 3-wire analog 4… 20 mA output signals, as well as Modbus/RTU digital interface. By offering various output signals, the sensor can be integrated seamlessly into any process.
Modbus Sensor Network with S331
The Modbus/RTU bus allows connecting several devices to a single bus line via Daisy-Chain. For example, up to 16 devices to a STUO Data Logger S331. The S331 is a powerful yet cost-efficient data logger and display solution.
Pressure Sensor and OLED Display
The S215 is offered with an integrated pressure sensor, combining a pressure and dew point sensor into a single instrument. The optional OLED display directly mounted on the sensor provides real-time values at the point of use. The display can be rotated by 340 ° to fit in any application. (Not available with 2-wire option)
