PR2 SDI-12 Profile Probe, 40cm, PR2/4-SDI-12

The PR2 SDI-12 Profile Probe is a digital alternative to the analogue PR2 Profile Probe. SDI-12 compatibility allows integration into new and existing SDI-12 systems.

The PR2 SDI-12 Profile Probe builds on the reputation and field-proven technology of the analogue PR2. By adopting the widely used SDI-12 interface (v1.3), the PR2 SDI-12 Profile Probe can be integrated with an even wider range of data loggers, sensors, and equipment. SDI-12 is an established communication standard adopted by many manufacturers of environmental monitoring and control equipment. It is popular because it allows large numbers of sensors (from many vendors) to be connected to a logger via a simple cable network, thereby reducing the cost and complexity of wiring large sensor installations. The PR2 SDI-12 Profile Probe conforms to the industry standard SDI-12 (v1.3) specification.

Cables and connectors

The PR2 SDI-12 Profile Probe has a high-quality, stainless steel IP67-rated connector (M12 x 5-way) connecting to the standard Delta-T range of M12 x 5-way cables and accessories. (NB: The M12 x 8-way range of cables used for an analogue PR2 connection is not compatible with the SDI-12 version of the PR2. (Analogue and SDI-12 sensors cannot be mixed on the same cable system.)

GP2 SDI-12 Data Logger—an ideal partner

The PR2 SDI-12 Profile Probe is fully compatible with the SDI-12-enabled GP2 Data Logger and Controller, which features a simple point-and-click configuration. Up to 50 SDI-12 PR2/6 Profile Probes, or up to 62 SDI-12 PR2/4s, can be connected to a single GP2 SDI-12 Data Logger (subject to cable length and power requirements). In addition to SDI-12 input, the GP2 can log 12 analogue channels. The SDI-12-enabled GP2 Data Logger and DeltaLINK enable quick and easy creation of sensor networks without the need to resort to the often-complex programming methods typically employed by other manufacturers. Due to the flexibility of the SD1-12 interface and the GP2 Logger, multiple power and cabling configurations may be possible when building a sensor network. Please refer to the PR2 SDI-12 Profile Probe User Manual for further information. Alternatively, please contact sales@lasec.com to discuss your application in detail. The SDI-12 Profile Probe’s electronics have been designed to improve power efficiency, reducing the overall power requirement. This is an important advantage for remote site applications.

HH2 Moisture Meter

The HH2 Moisture Meter can display readings from the PR2 SDI-12 Profile Probe*. This is a great advantage for customers who value the freedom to use the PR2 SDI-12 Profile Probe in both installed and portable applications. The PR2 SDI-12 Profile Probe is connected to the HH2 Meter by the SDI-12/5W-HH2 cable.

*Please note that the HH2 only reads SDI-12 digital data from the PR2 SDI-12 Profile Probe; it is not a general-purpose SDI-12 meter.
