4 ... 20 mA 2-wire / 3-wire and Modbus/RTU
Operating pressure of 0 ... 1.6 MPa (Optional 35.0 MPa)
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.
Dew Point Monitoring According to ISO 8573-1
The plug & play dew point solution monitors the compressed air quality and purity according to the ISO 8573-1 standard. Meeting these requirements help to 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 Dew Point Sensor are 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 wires option)
Robust Materials for High Reliability
The new dew point sensors have been redesigned from ground up, integrating the latest technology and all our experience. The sensors are fully backwards compatible to existing installations.

SUTO Exchange Service
The SUTO Exchange Calibration Service eliminates downtime and enables users to have a seamless record of their dew point measurements.
The user receives a calibrated instrument in advance with a calibration certificate and the same instrument settings. The onsite instrument is then switched with the calibrated one and returned to the supplier. here you can find more information about our SUTO Exchange Service.
Please contact us here for special requests, such as custom dew point ranges or different gas types or applications.
