PPS-02-T-A-LL-PP-CA

A: Absolute (relative on request)

LL: 10 m¹ plus L x 5.0 m increment sensor cable.

PP: 300/500/1000 kPa absolute pressure range.

CA: 45, 50, 32, 36

Example:

PPS-02-T-A-25-300-45

Pore Pressure Sensor, equipped with a Temperature sensor, Absolute pressure, 25-meter cable, a pressure range of 300 kPa and

45 mm SS P-I adaptor.

Auxiliary pieces and consumables:

Ø36 x 25 mm CPT Push-in adaptor rod, with threads from all commonly known CPT-manufacturers.

Silicone oil.

Cable repair kits.

Communication:

The PPS-02-T is designed to be connected to the MicroSense-NBIoT

or the TinySense-4 low power wireless datalogger.

The MicroSense is suited for one sensor and the TinySense-4 can connect to four PPS-2-T sensors at once.

Both data communication devices operate on the LTE-NB, LTE-M1 and the GPRS (2g) nationwide networks.

Data is sent in a standardized way such as MQTT, HTTP mail, UDP or TCP. Data is presented as a JSON datagram.

Data presentation:

A feature of the above communication equipment is that it can transmit data in many standardized formats.

This makes it suitable for almost all commercially available Cloud‑Based, data presentation platforms, including the Inducon Data‑panel as a service. Plus, many others such as: Thingsboard, AWS, Azure etc. etc..
