Industrial Temperature Monitoring and Control
The System records measurements and stores their results in nonvolatile memory of the control unit (TTA-08) providing the option to submit them to the data processing system.
The key component of Multipoint Temperature Measurement System is TTA-08 access and sensor control unit.
The following components are required to build the Multipoint Temperature Control System:
- System controller – TTA-08 access control unit
- Power/Interface Unit
- Required number of cascade temperature sensors
Power/Interface Unit features two connectors to which the opening link of the sensor chain and it closing link are connected thus forming the sensor ring.
To control and monitor temperature remotely at several objects at a time Multipoint Temperature Measurement System is equipped with the dedicated software, which is SNMP-based TTA Monitor network monitoring application.
To communicate with devices either SNMP or internal communication protocol is used.
Cascade temperature sensor
The dedicated cascade temperature sensor is an important component of the system. It allows to deploy comprehensive Multipoint Temperature Measurement and Monitoring System based on TTA-08 access and sensor control unit.
The number of the temperature measuring points can vary from a few points up to several dozens of points and threshold temperature values can be set for each sensor.
The cascade temperature sensor is an electronic unit with 2 RJ-45 connectors placed in a polymeric enclosure. The temperature sensors are interconnected serially and they are connected to TTA-08 controller using power/interface unit.
The temperature sensors are connected using the standard patch cords or CAT5/5e UTP cross patch cords used to build local computer networks. The patch cord can be from 0.5 to a few tens and even a few hundreds of meters long.
When the chain with very long connections (up to several hundreds of meters) is being built then an intermediate power/interface unit and power supply shall be additionally installed.
The current temperature values can be obtained from the sensors in two ways:
- Through Web interface featuring the tab with the temperature values (up to 25 sensors)
- Using SNMP-based connection to the monitoring system. In this case the temperature values can be obtained from as many as a few hundreds of sensors
Multipoint Temperature Measurement System allows to enter high and low temperature limit values as required for each connected sensor providing the option to issue SNMP trap message when the limits are exceeded. Information specifying that the limit temperature values have been exceeded is stored in nonvolatile memory of TTA-08.

Permissible absolute accuracy limits:
- ±0.5°C typical accuracy @ 25 °C
- ±1.0°C in 0°C-70°C range
- ±1.5°C in -40°C-120°C range
Power consumption: 3W
Supply voltage: 20-70V
Dimensions of system units:
- TTA-08 controller: 150х100х40 mm
- Cascade temperature sensor: 80х35х15 mm
Average lifetime: 10 years at minimum
Multipoint Temperature Measurement System is not limited to measuring temperature. Its application can be significantly expanded by using optional products.
The following sensors for monitoring the standard security equipment can be connected to TTA-08 access control unit:
- motion sensor
- broken glass sensor
- window/door sensor
- smoke sensor
- flood sensor
TTA-08 monitoring and control unit features 2 inputs designed to connect 220V AC voltage detection sensors and one input designed to measure battery voltage.
Battery voltage is measured within a range from 0 to 90VDC with +/- 1V accuracy.
The system software allows to assign high and low battery voltage thresholds for alarm reporting (SNMP trap, sound or visual alarms).
Using Multipoint Temperature Measurement System allows to create multiple comprehensive solutions for controlling and monitoring temperature modes of remote facilities:
- Temperature mode measuring system for data processing centers and server rooms
- Temperature monitoring and measuring system for:
– industrial premises;
– storehouse facilities;
– pharmacy premises;
– food production and refrigeration facilities.
- Temperature monitoring and measuring system for telecommunications facilities using GSM and LAN networks.
SNMP-Based Network Control and Monitoring System
The network device monitoring system is an SNMP-based turnkey solution.
To control and monitor several Multipoint Temperature Measurement Systems simultaneously you can optionally use TTA Monitor application.
The application designed to communicate with devices can use either SNMP or internal communication protocol. TTA Monitor can operate under Windows or Linux operating systems.
TTA Monitor application features the standard multiwindow interface displaying the main window with child windows that can be opened from the main window.
All monitored system devices are displayed as a tree within the main application window.
Each connected device has parameter monitoring and configuration forms implemented for the device itself and its connected sensors.
Remote object monitoring will allow the operator to find correct solutions in emergency cases, instruct the staff accordingly, switch systems remotely or change settings of the devices and connected sensors.
Optional products will allow to monitor fire safety of the facilities, prevent them from intrusion, monitor 220V AC availability at the facilities and monitor battery voltage.
