DCX22_Datalogger for pressure and temperature Riels - 1

DATALOGGER FOR PRESSURE AND TEMPERATURE Autonomous data collector 100% waterproof Riels DCX-22 is an autonomous, battery powered instrument made of stainless steel designed to record water depth (pressure) and temperature over long periods. Two versions are offered: DCX-22: The sensor, electronics and battery are housed in a sealed stainless steel tube, for submersible deployment. For data read-out the DCX-22 must be recovered from the measurement point. The O-ring sealed end cap is then removed to access the data port. The DCX-22 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 PC then calculates the differential pressure resp. the water depth by subtracting the two measured values. Tutti i dati ed i contenuti di questa scheda sono di proprietà esclusiva di Riels Instruments DCX-22 SG/VG: The sensor is connected by waterproof cable to a surface mounted housing with the data read-out port. This arrangement allows for easier data recovery from fixed installations. The DCX-22 SG/VG does not have to be removed from the dip pipe for data read out. The DCX-22 SG/VG is supplied with a 2” diameter fixing plate to enable mounting at the top of the dip pipe. The sensor can be sealed gauge SG, or vented gauge VG, the cable carries the vent tube for VG version sensors, vent port in the housing is protected by a breathable Gore-Tex® membrane. The electronics employ the latest microprocessor technology, which give high accuracy and resolution for the pressure and temperature signals from both the depth sensor and the barometric sensor. The measured values are mathematically compensated for all linearity and temperature errors of the pressure sensors. The use of a non-volatile memory ensures high data security. The electronics housing is mounted at the top of the borehole to give easy access for data downloading. The level sensor (diameter 22 mm) is connected via a sealed cable to the bottom of the electronics housing. Installation is quick and simple, using fixing devices in various sizes, suitable for cap lock units of different manufacturers and for well access points starting from 1” (caps starting at 2” include a hole to lower a dip meter). Thus enabling measuring stations to be set up at considerably lower costs compared to conventional systems. The modular design offers the user the two options for collecting the data. Standard design requires the user to visit the location, connect via data-cable and download data. The optional GSM-1unit allows the transmission of data, and instructions (re-programming) to the data-collector from/to a remote location. The data can be sent to any mobile phone as a short message (SMS).
