dol SENSORS DOL 104 Humidity Sensor

PRODUCT DESCRIPTION

DOL 104 is a high-precision sensor for measuring relative humidity. It is intended for application in livestock houses but is also well suited for a number of industrial applications

MAINTENANCE

IMPORTANT
Clean DOL 104 using water and a brush. Do not use:

High-pressure cleaner
Highly compressed air

Solvents
Corrosive/caustic agents

Alcohol-based disinfectants
During cleaning and disinfection, the sensor must be protected using a protection cap and be placed in vertical position.

After the sensor has been exposed to water and condensation, the sensor requires time during which the relative humidity is less than 80% in order to measure correctly.
Do not bend the sensor as this would inflict permanent damage on the electronics of the sensor. dol-sensors reserve the right to change this document and the product herein described without further notice.

LED Green	Red	LED/LIGHT PROTOCOL Status
ON		Operation OK
Flash		Outside normal range (below 10% RH or exceeding 95% RH)
	ON	Connection error Load error, Fig 4.
	Flash	Sensor defect Over/under voltage alarm Overload

INSTALLATION

For optimum mounting of the sensor, use mounting clips or mount it free-hanging in the cable. The sensor element requires free air passage.
See Figure 1. Mount the sensor so it is not exposed to direct sunlight, as this would affect the measurement.
REMEMBER TO PUT ON A PROTECTION CAP BEFORE MOUNTING THE CABLE.
