Quick Start
System Overview
- The LIBERO Gx realtime data logger family described in this document are used for temperature monitoring. The measured values are transmitted via the cellular network to a monitoring software (ELPRO Cloud) which stores and analyzes the data, provides alerts if alarm limits are violated, and generates reports. The system provides superior visibility and transparency in meeting GxP requirements. The sensor-based monitoring software is easily accessible via a web browser and is also used to configure the devices.

External Pt100 Probes for LIBERO GE
LIBERO GE can be used for different applications, depending on the sensor element. ELPRO offers standard probes for three main applications:
- Cryogenic shipments and storage
- Dry ice shipments and storage
- Freezer (-25 °C..-15°C, typical) / fridge (+2 °C..+8 °C) / ambient (+15 °C..+25 °C) shipments and storage
to ensure correct measurement values, do only use external sensor elements provided by ELPRO
Cryogenic shipments and storage
For cryogenic applications the LIBERO GE is usually mounted directly to the container or the container lid, using the optionally available bracket with the sensor leading into the tank. ELPRO offers an easy, turnkey service for mounting the assembly and calibration.
ELPRO offers two Pt100 standard probes for cryogenic applications with M8 connector in different lengths:
- PRO_PT100_ST300D3_M8_CRYO (part number 802287)
- PRO_PT100_ST350D3_M8_CRYO (part number 802288)
Dry ice shipments and storage
Also in dry ice applications, the LIBERO GE is usually attached to the outside of the container using the optionally available bracket and the sensor leads into the tank. ELPRO offers an easy, turnkey service for mounting the assembly and calibration.
For this application, ELPRO offers two standard probes with a probe length of 10 cm and Teflon cable in different lengths:
- PRO_PT100_ST100D4_PTFE1_M8 (part number 802284)
- PRO_PT100_ST100D4_PTFE2.65_M8 (part number 802285)

- PRO_PT100_P20D5_PLA2.65_M8 (part number 802291)
Extension of sensor cables
An extension cable with two M8 connectors at a length of 1m is also available to attach the data logger and the probe.
ATTENTION:
Total cable length (including sensor and cable tail on the data logger) must not exceed 3 m!
- ECA_PLA_1M_M8 (part number 802282)
M8 connector incl. mounting service on Pt100 probe
ELPRO offers a mounting service, adding an M8 connector to a Pt100 temperature sensor in order to use any 4-wire Pt100 probe in combination with LIBERO CE.
