High-precision autonomous level logger — DCX-22

Description

The DCX-22 data logger is a standalone device with a stainless steel housing, powered by a lithium battery. The logger allows measuring and recording water level (pressure) and temperature over extended periods.

Two versions of the device are available:

DCX-22

All sensor parts – the sensitive element, electronics, and housing with battery – are housed in a single welded sealed enclosure. To download data, first, the logger must be removed from the measurement point. Then, the cap must be removed to access the data reading connector. The DCX-22 logger uses an absolute pressure sensor. This is acceptable in cases where atmospheric pressure changes can be neglected, or if there is a barometric sensor on the surface measuring atmospheric pressure in parallel. In this case, you can accurately calculate the liquid level on a computer using the logger readings and atmospheric pressure values.

DCX-22 SG/VG

In this version, the connector for connection is mounted on the surface to provide easy access to the data reading connector. Installation of this version is easy and quick. Various sizes of mounts can be used. Installation can be carried out in wells with a diameter of 1" or more. The surface head for storing the connection connector must have a diameter of at least 2”. The logger versions can be relative with separation (SG) or relative with a capillary (VG). In the latter case, a special breathing tube runs along the cable. Inside the housing, the breathing tube is protected by a special seal made of Gore-Tex^® material.

The device is equipped with a modern microprocessor, allowing high accuracy and high resolution in measuring level and temperature. The measured values undergo software processing and temperature compensation to obtain a linear signal. The logger uses a stable memory device protected against voltage surges, ensuring complete data preservation. The modular sensor design allows the DCX-22 SG/VG to be used with various mounting devices and enables connection of the logger to a GSM module. GSM is offered as an option and allows data transmission from the logger to a modem. Data can also be sent to a mobile phone via a standard SMS message.
