S220 Dew Point Sensor

S220 Dew Point Sensor

S220 is a very compact ultra-low range dew point sensor for high purity air/gas systems. This unit is ideal for mounting directly into compressed air desiccant dryers through standard G1/2″ male thread and provides both 4-20mA and SDI (SUTO Digital Interface) communications to interface with plant control systems and other SUTO products.

  • Range -100degC to +0degC
  • Pressure range -0.1 to 1.6MPa
  • Output 4-20mA 3 wire or 2 wire loop powered
  • Power supply 12-30Vdc 30mA
  • RS 485 Modbus and dual 4-20mA output options
  • Integral pressure sensor option
  • OLED display option

The compact dimensions, G1/2″ mounting and IP65 rating allows easy installation of S220 sensors in ultra dry compressed air systems. S220 offers several variants for dual variable measurement such as dew point and temperature or dew point and pressure with dual 4-20mA outputs or Modbus communications. The QCM sensor is designed to be sensitive to moisture changes in the ppb range which makes it both accurate and very quick to respond to changes in the airstream.
