Description
The DCX-22 AA data logger measures and records liquid level using two absolute pressure sensor technology 2 AA. The sensor submerged at depth measures the liquid level. On the surface, there is an additional barometric sensor (also sealed) for measuring atmospheric pressure and an electronics unit. The sensor does not use capillary tubes. This means that the DCX-22AA is suitable for harsh application conditions and environments with high humidity. Temporary full flooding of the system is also possible.
The electronics and battery housing are located at the top of the well, providing convenient access for data collection. The submerged probe (22 mm diameter) is connected to the electronics housing via a cable. Installation is very quick and convenient, with various mounting options available. The device is suitable for installation in any tubes with a diameter greater than 1”. Thus, using this system allows savings compared to standard systems commonly used.
The sensor is equipped with a latest-generation microprocessor, which ensures high accuracy and resolution of signals received from pressure and temperature sensors. Measured values are compensated for nonlinear and temperature deviations of the pressure sensors.
The use of direct current guarantees the preservation of measured data.
The modular design of the DCX-22 AA offers the user two data storage options: the standard version requires the user to visit the installation site to connect to the sensor. The optional GSM-1 module allows remote data retrieval and sensor programming. Data can be sent to any phone via a regular message (SMS).
