No P/N Calibration certificate No P/N The 3 Dew Point Transmitters S211, S215 and S220 are offered in different versions. Depending on the version the options might be different, see table below for an overview about the different models, their signal output and available options. -
Page 14: Installation Requirements
• The device is for indoor use only! At an outdoor installation, it must be protected from solar radiation and rain. • It is strongly recommend not to install S211 / S215 / S220 permanently in a wet environment, which usually exists right after a compressor outlet. -
Page 15: Installation Procedure
3. Connect the measuring chamber to the compressed air system using a quick connector. Make sure the Dew Point Transmitter is screwed on the chamber before connecting. The measuring chamber will create a purge flow. S211/S215/S220... -
Page 16: Install With By-Pass Measuring Chamber A699 3493
Note: The full flow must pass the measuring chamber. Ensure a certain flow rate to get fast response time. 2. Connect the outlet of the chamber to your system using the 6 mm hose quick connector. See figure below for details. S211/S215/S220... - Page 17 If there is no pressure difference between P1 and P2, there will be no flow through the chamber and therefore the response time will be very slow or the device will not even respond at all to the dew point changes.

Page 28: Connect Modbus/Rtu Devices To A Master
9.2.2 Connect Modbus/RTU Devices to a Master Sensors and devices with a Modbus/RTU output can be connected to a Modbus master device. This master can be either SUTO displays and gateways or any third-party Modbus/RTU master. See below specifications of the Modbus/RTU connections. - Page 29 (A553 0123). • The shield must be connected at one end to the master GND connection. • At the end of the bus, a 120 Ohm resistor should be placed a termination resistor. See the below picture for details. S211/S215/S220...
