CTD (Conductivity, Temperature & Depth) Sensors
CTD Sensors are primarily used for detection of changes occurred in conductivity, salinity, TDS (Total Dissolved Solids), temperature and depth. Conductivity, Salinity and TDS are measured by one sensor. Salinity is defined as the presence of salt and other seawater compounds in the water. Conductivity is traditionally defined as “the ability of passing electric current”. Salinity and Conductivity combined are used as the parameter for checking the water condition in water log area, for Irrigation purposes. Depth of water is also the measure of the water login ability of the underground water. So CTD sensors play a vital role in determining the present condition of Irrigation system, Land, Water Qality and can be useful for Irrigation, Agriculture, Water Quality Control, Pesticide, Construction companies & departments and Farmers.
What is it and why do we use it?
A CTD — an acronym for Conductivity, Temperature, and Depth — is the primary tool for determining essential physical properties of sea water. It gives a precise and comprehensive charting of the distribution and variation of water temperature, salinity, depth and density that helps to understand how the fresh, ground, salt and ocean water affect life.
How does it work?
The CTD is made up of a metal probe attached to a Data Logger via communication cable. The probe is lowered down to the ground water and user can observe the water properties in real time via a conducting cable connecting the modem in CTD logger. A remote GSM modem can receive the real-time values via cellular network. Interval for taking the reading is configurable via software locally and remotely.
CTD sensors has the wide variety of application such as Control Measurement in areas of potential pollution, e.g.
CDigital has installed CTD Sensors at different locations. Some of them are:
