Detailed Product Description
S231 Compressed Air Dew Point Transmitter for Ex Applications (-50~+20 °C Td)
OVERVIEW
The SUTO S230 / S231 Heavy-Duty Dew Point Transmitters provide reliable, long-term stable dew point monitoring for compressed air and gases in harsh and hazardous applications. The fast response time ensures safe and reliable indication whenever dew points are out of valid ranges.
FEATURES

 

· Ex Areas Solution

The optional IECEx approval makes it the perfect tool to be used in explosive environment (Ex area). SUTO’s unique dual sensor technology optimizes sensor sensitivity and accuracy by automatically selecting the ideal sensor type for the situation.

· User-Friendly Output Signals

The S230/S231 come ready to use and simple to install with your choice of 4-20mA or Modbus RTU (RS485) outputs. If required, parameters can be quickly monitored through the SUTO service software. The transmitters can also be connected the SUTO S331 (stationary) or S551 (portable) data logger and the data can be transferred for further analysis.

 

APPLICATION SCENES
 

S231 Dew Point Transmitter comes with a standard range from -50… +50 °C Td, offering a wide range of dew point monitoring applications for compressed air and gases.

  1. Dew point measurement in explosive environments
  2. Outdoor / all-weather flow applications
  3. Explosive environments
