This precision dew point sensor is suitable for refrigerant, desiccant, drum and membrane dryers. The sensor design provides long-term, reliable, high-accuracy measurements. Its proven polymer technology provides strong contamination resistance and ability to withstand exposure to higher moisture levels. This sensor is deal for dew point ranges of -60°C to +60°C (-76°F to +140°F).
The Dew Point Sensor is available with an in-built display or without a display. The display option includes an alarm relay and allows you to adjust the dew point settings (gas type, measurement units, modbus and 4-20mA settings, etc).
Best suited to
- Compressed air and gas systems to 4 Mpa (600psi)
- Refrigerant, membrane, drum or hybrid dryers operating at or above -50°C (-58°F)
- Dew point range of -60°C to +60°C (-76°F to +140°F)
- Tough Conditions
