Wired Temperature and Humidity Monitoring System

Since 2009 year PJSC TERA designs, manufactures and installs wired / wireless automatic temperature and humidity monitoring systems (ATHMS) for the companies being into pharmacological and food industries. Every complete monitoring system successfully passed required validated procedures by TERA’s customers corresponding to requirements GMP, GDP, GCP, GPP, FDA 21 CFR (Part11), GAMP and HACCP.

WHAT’S INCLUDED

ATHMS includes the following parts:

  1. CS10600 Data Logger is using for data collecting of wired transducers. This device acts several functions: aggregates and saves information receiving from transducers, provides with data access via Internet using the web interface of the pre-installed software inside, notifies alarms, functions as database server. Data Logger has RS485 port for TSP RST & DVT RST wired transducers connection. Регистратор-вебсервер использует порт RS485 для подключения проводных преобразователей TSP RST и DVT RST. Internet access implements via Ethernet or built-in 4G/LTE modem. Data Logger is fixing inside of a plastic box along with N1-UPS Uninterruptible Power Supply. Data Logger is able to aggregate and save data of up to 30 wired transducers. Non-volatile memory is able to store information of the period by over than 10 years.
  2. Y-Case Wired Temperature Transducers TSP RST and Y-Case Wireless Humidity & Temperature Transducers DVT RST designed for placing it in warehouses, on shelvings, shelves, in freezers and refrigerators. Transducers has dual-channel temperature and humidity sensor. It may have one or two more channels for temperature probe connection. An external temperature probe measures temperature of goods inside of a package or inside of a freezer. Transducers use RS485 interface for data transfer. It has magnetic holder for comfortable placing.
  3. The shield with the uninterruptible power supply supplies with power CS10600 data logger. It transduces mains power 230 VDC to 24 VDC. The shield contains two replaceable AGM storage batteries (gel-based lead-acid) with capacity 9 Ah for each one to power the data logger and a net of coordinators uninterruptibly during 20 hours in a case when there is no mains power (depends on a number of transducers on RS485 line).
  4. LOCAL WEB is pre-installed application in Data Logger, which uses WEB HMI interface, developed with web technologies. This application developed to fulfill all necessary functions of the monitoring system in real-time, namely transducer’s data collecting, processing, displaying and archiving, notifying alarms, database storing, user’s action and event logging, access, roles and rights administration, data export, reports and graphs generating, etc. The application requires Internet or Ethernat access and Google Chrome browser to get access for users.

FEATURES

Advantages

  • The most budget option for warehouses with big number of rooms, low ceilings and number of storeys
  • Transducers can be easily mounted and dismounted by M12 connector, that eases to serve it by staff and to fulfill periodical verification
  • Transducers are consistently connected on a single RS485 line
  • Much stable system due to data transfer by a cable between a transducer and Data Logger
  • Wired transducers are cheaper a little comparing to wireless ones
  • The distance of data transfer between a transducer and Data Logger can reach 1000 meters
  • Real response time of a transducer starts from 1 second

Disadvantages

  • Montage is expensive a little, than the wireless system due to cabling
  • It needs more time to montage
  • Montage is fulfill by persons with engineering qualification
  • In case of moving the system to the new spot, it requires new cabling
  • Long cabling lines with transducers require installation an extra power supply at the end of line

PLACING MONITORING SYSTEM 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 MONITORING SYSTEM 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.
