Compressed air dew point
Compressed air dew point monitoring
Dew point meters, transmitters and hygrometers for compressed air systems, dryers, OEM skids and dry process gases.
Application overview
Why dew point matters in compressed air
Dew point indicates the moisture level in compressed air. Reliable monitoring helps protect pneumatic equipment, dryers, instruments, production processes and quality-critical applications.
Dryer monitoring
Continuous dew point control after refrigerant or adsorption dryers.
Pipeline installation
Direct installation, sampling line or bypass according to process conditions.
Alarm and output
Local display, relay alarm and analog output for control systems.
Selection path
How to choose a dew point instrument
1
Dew point range
Define the expected dry range and alarm threshold.
2
Pressure
Confirm line pressure and whether pressure dew point is required.
3
Installation
Choose direct mount, sample cell, bypass or portable kit.
4
Output
Specify display, alarm relay, analog output or digital communication.
Suitable solutions

FAQ
Common questions
Why measure dew point in compressed air?
Dew point shows the amount of moisture in compressed air. Monitoring helps prevent corrosion, icing, product contamination and dryer failure.
Where should the sensor be installed?
Common locations include the dryer outlet, critical branch lines, process air supply points and quality-control test points.
Do I need an online or portable instrument?
Online instruments are best for permanent monitoring and alarms. Portable analyzers are useful for checking multiple points, maintenance and periodic audits.
What data is needed for model selection?
Specify gas, pressure, expected dew point range, installation method, output requirements, display or alarm needs and operating conditions.
