- with capacitve Mela® humidity sensing element
- with current or voltage output
- compact sensor in a high-grade steel housing
- IP 65 protection
General information
Accuracy
• Humidity ±2% rh (5...95 %rh at 10...40 °C)
• Temperature
± 0,2 K with voltage output
± 0,2 K - 0,6 K with current output
The sensors of the VC and VR series are rod-shaped, compact sensors. They can be used in a wide range of applications and have been specially developed for use in extreme conditions. Their design also makes them ideally suited for performing equilibrium humidity measurements in bulk materials and in brickwork.
