Bestech Australia gives the DCX-22 ECO from Keller — a submersible, battery-powered, autonomous data logger designed for recording strain and temperature over lengthy intervals of as much as 10 years. Housed in a 22 mm chrome steel tube, the sensor can be utilized with a second data logger to behave as a barometric strain sensor to compensate for the affect of barometric strain in shallow water depths.
The sensor is designed with the newest microprocessor expertise to supply high-resolution alerts. This characteristic permits for data linearity and temperature errors to be mathematically compensated. It additionally gives non-volatile reminiscence storage, which ought to guarantee excessive data safety.
The collected data might be retrieved by firstly recovering the data logger from the deployment level. Then the top cap, which is sealed by two O-rings, is eliminated to entry the serial interface to gather the data. The battery is rechargeable through USB reference to the serial Ok-114M converter related to the PC.
The DCX data logger is paired with KOLIBRI software program for studying and visualising data in addition to conducting evaluation resembling differential strain calculation. The sensor might be configured to solely acquire helpful data or file data at shorter intervals. It can be set to avoid wasting the set up data and site the place the sensor is deployed.
The measurement vary is 0.8–1.3 to 0.8–11 bar, with 0.1% typical accuracy.
