KELLER DCX-22-ECO Pressure Level loggers

Product Description

 
 
 
   
 
The DCX-22-ECO data loggers are a cost-effective alternative to the highly accurate DCX-22 loggers and are only available in the cable-free «cigar» design. Thanks to their long-life battery, they can keep measuring the water level, water pressure and temperature for years (up to 10 years at a rate of one measurement per hour). The data logger can be configured using the supplied software (measurement interval, incident management, delayed measurement start etc.) and data that has been read can be displayed in a graph or chart, corrected using air pressure values, converted into fill levels or other units, and exported.
 
The DCX-22-ECO is an autonomous, battery powered instrument made of stainless steel designed to record water depth (pressure) and temperature over long periods. The sensor, electronics and battery are housed in a sealed stainless steel tube, for submersible deployment. For data read-out the DCX-22-ECO must be recovered from the measurement point. The O-ring sealed end cap is then removed to get access to the data connection.
 
The DCX-22-ECO works with an absolute pressure sensor. In shallow water depths where the influence of barometric pressure changes should be considered, it is recommended that a second data collector DCX-22 (Baro) is placed at the surface, to record the barometric pressure. The Windows software KOLIBRI Desktop then calculates the differential pressure resp. the water depth by subtracting the two measured values.
 
The submersible level transmitter with a 22 mm diameter – suitable for installation in monitoring pipes from 1” – contains a battery compartment with a double O-ring seal (battery life approx. 10 years) as well as the electronic circuit with microprocessor technology. This records the pressure and temperature with high accuracy and resolution, mathematically correcting any linearity or temperature errors in the pressure sensor. A non-volatile memory is used to ensure a high degree of data security. Thanks to the various configuration options, the data logger can be adapted to suit the measuring site so that only useful data is saved, or a significant event is detected and measured values are then recorded over a shorter interval. It is also possible to store installation data and comments about the measuring site in the transmitter.
