A new product range is available for measuring relative humidity and associated variables in process and environmental test applications.
Handheld meter detects moisture in oils
The Vaisala Humicap MM70 handheld moisture and temperature meter for oil detects moisture in lubrication, hydraulic and transformer oils.
The sensor is based on infrared optics and laser technology.
What makes it unique is that it helps its users to determine the friction coefficient of the road and therefore identify the prevailing driving conditions.
The new sensor will serve as an effective decision making tool for winter maintenance authorities.
Road salting, vital for traffic safety, can now be better timed, which reduces both costs and the strain on the environment.
The sensor can also be used in other road weather applications, such as weather adaptable speed limit systems, maintenance quality control, maintenance of walkways and garage slopes, as well as with automatic de-icer spraying systems.
The new road surface state sensor is installed differently to traditional sensors.
Previously, sensors have been installed on the road surface.
The new sensors are installed 3-10m up on a post by the road side, which makes installation and maintenance work much easier, and less dependent on weather conditions or timing.
The sensor has been developed in co-operation with the Technical Research Centre of Finland (VTT) and the Finnish Road Administration.
Before official sales launch, it has been in trial use in Finland, UK, and the United States.
Vaisala has also introduced a new sensor for road surface temperature measurement. Request a free brochure from Vaisala ...
