Evaporation Sensor (Capacitance Type)

Overview

The EMCON Evaporation Sensor (Capacitance Type) is designed for
meteorological observation where reliable measurement accuracy and
long-term stability are required.

The sensor provides a linear output corresponding to changes in
water-level fluctuations inside an evaporation pan. It is designed
for long-term operation in hostile weather conditions with minimum
maintenance requirements.

Key Features

• Capacitance-type evaporation sensing
• Linear output for water-level fluctuations
• Long-term stability
• Good repeatability and accuracy
• Does not respond to changes in ambient temperature
• Does not respond to atmospheric pressure fluctuations
• Fully sealed construction
• Suitable for remote, hostile and coastal areas
• Small-size design
• Fully indigenous make
• Excellent sensor interchangeability
• Minimum maintenance requirements

Measurement Principle

The sensor is designed to measure changes in water-level fluctuations
inside an evaporation pan. The capacitance-based sensing system
provides a linear output corresponding to changes in the water level,
allowing evaporation-related water-level changes to be monitored.

Applications

• Meteorology
• Agro Meteorology
• Hydrology
• Evaporation pan monitoring
• Long-term environmental observation

Water-Level Measurement

The sensor provides a linear output corresponding to changes in water
level inside an evaporation pan. The available measurement range is
0 to 300 mm.

Long-Term Stability

The EMCON Evaporation Sensor is designed for applications where
long-term stability, repeatability and good measurement accuracy
are required. It can operate for extended periods with minimum
maintenance.
