PJSC "TERA" has been engaged in the development, production, and installation of wired and wireless automated humidity and temperature monitoring systems for the pharmaceutical and food industries since 2009. All installed monitoring systems have successfully passed validation procedures at PJSC "TERA" customers in accordance with the requirements of GMP, GDP, GCP, GPP, FDA 21 CFR (Part11), GAMP, and HACCP.

COMPONENTS OF THE WIRELESS SYSTEM

The wireless monitoring system based on GSM and Wi-Fi loggers consists of the following components:

1. Wireless GSM and Wi-Fi humidity and temperature loggers use a built-in GSM or Wi-Fi modem to transmit data to a cloud server. The device operates on the principle of waking up, measuring, transmitting, and going back to sleep. In the absence of a connection to the operator’s tower or Wi-Fi router, the logger stores the collected humidity and temperature data in its internal non-volatile flash memory. The logger features a high-contrast OLED display that shows humidity and temperature readings for all measurement channels. Additionally, the display shows signal strength, battery charge, and serial number. The logger comes with a rubber boot for protection against impacts and falls and has a built-in magnetic mount. The logger is equipped with two IP67 M8 connectors, to which one or two external Pt1000 thermocouples or air humidity and temperature sensors (SHT) can be connected. The device also has a USB-C port for connecting the battery charger. The logger's replaceable lithium battery, type 18650, can be quickly replaced by the user if needed.
2. ColdChainCloud software, hosted in the cloud, provides a user-friendly WEB HMI interface built on web technologies. The application is designed to perform all necessary monitoring system functions in real time, including data collection, processing, display, and archiving from sensors, alarm signaling, database management, logging user actions and events, administering access, roles, and user rights, data export, report and graph creation, and more. Users need an internet connection and the Google Chrome browser to access the ColdChainCloud application.

FEATURES OF THE WIRELESS SYSTEM

Advantages of the wireless monitoring system:

• The most budget-friendly option for pharmacies, vaccination points, medicine storage rooms in hospitals or clinics, and food storage rooms in restaurants and cafes—places where it's necessary to monitor one or more points within a single room
• Loggers are easily installed and removed thanks to magnetic mounting, and the system can be easily relocated to another site if needed.
• Simple installation that can be performed by the user.
• The wireless system can be used for equipment and room mapping (finding critical points).

Disadvantages of the wireless monitoring system:

• The radio signal from the logger can be blocked by external obstacles (pallets with goods, walls, etc.) or radio interference.
• Battery life depends on the polling frequency of the logger (the more frequent, the quicker the battery drains).
• The practical polling frequency of loggers is no more than once per minute, with a recommended interval of once every 5 or 10 minutes.
• A monthly subscription fee is required for access to the ColdChainCloud cloud software and for mobile internet.

PLACEMENT FEATURES OF LOGGERS IN REFRIGERATORS

For air temperature monitoring in refrigerators (freezers, cold storage boxes, climatic chambers), single- and dual-channel GSM and Wi-Fi temperature loggers are used. The logger itself is mounted on the refrigerator body using a magnetic mount. One or two wired external thermocouples are routed inside the refrigerator chamber. The cable is either passed through a technical hole in the refrigerator (if available) or through the door (a special thermocouple with a flat cable adapter is supplied to avoid a gap at the cable entry point when the door is closed). If the refrigerator has two chambers with different temperatures, two external thermocouples are used, connected to the logger via two M5 connectors (DLT-20-2Pt model). For cold rooms, a hole is made in the sandwich panel, flanges with gland seals are installed on both sides, through which the wired external thermocouple is routed inside the room. PresentationThis conformity certificate confirms the conformity of the product with essential safety requirements of the following EC/EU New Approach Directives as amended. 2014/30EU    EMC Directive Harmonized standards used for the conformity assessment: EN 61326-1:2013 EN 55011:2016/A1:2017/A11:2020 The certificate has been issued on the basis of the tests of the product type sample.

PLACING ON SHELVING WITH PALLETS

Triple-channel transducer is using for air temperature and humidity monitoring by shelf storage. A transducer itself with built-in sensor is placing on bottom of a shelving by magnetic holder (a green mark on an image). An external probe is placing on top of a shelving (a red mark on an image), that’s connected to a transducer by M8 connector. A transducer with an external probe hides inside of rack to avoid physical damage while loading goods. Such approach solves several issues. Firstly, easy management of whole temperature gradient between of top and bottom of the shelving. That eases for a customer to search critical points on the shelving and to move transducers in the winter-summer mode. Secondly, it cheapens whole system by using triple-channel transducers with an external probe. The external probe costs three times less than a regular transducer.

PLACING IN REFRIGERATOR

Single-channel and dual-channel temperature transducers are using to check air temperature inside of refrigerators (freezers, refrigerator chests, climate cameras). A transducer itself is placing on the refrigerator case by a magnetic holder. One or two external temperature probes are placing inside of a refrigerator. A cable passes either through a technological hole in a refrigerator (if exists), or through refrigerator’s door corner. If a refrigerator has two cameras with temperature difference, then it’s using two external temperature probes, that’re connected to a transducer by M5 connector (2-15 Model). Installation for a refrigeration room require to make a hole in sandwich-structured composite by two sides, to mount a flange with a cable gland, and to lay an external temperature probe through it. Such approach has significant advantage. A transducer with indication placed outside, and it allows to view temperature value without open the door.
