Temperature Scanner

Libratherm offers Digital Temperature Scanners model MSI-8 for 8 channel, MODEL MSI-16 for 16 channel, Model LSI-16 for 16 channel with higher accuracy, Model MSI – 8000 is Microprocessor based 16 channel and Model DATALOG – 16 is microprocessor based DATA LOGGER. All these models are suitable for continuous monitoring of temperature or process variables at different locations. These instruments eliminates the need of number of individual temperature or process indicators and hence saves on cost and panel space. Each model offers different features and can be used as per the requirement in terms of number of inputs, accuracy and price.
Model MSI-8 accepts 8 thermocouples or RTD (Pt-100) sensors. The temperature is displayed along with the respective channel number. The scan rate is adjustable from 2 to 20 seconds. The standard features include SCAN/HOLD facility and manual increment of the channel number using ADVANCE front panel membrane switch. MSI-8, can also be used to monitor other process parameters. MSI-16 offeres similar features but for more than 8 channels with larger display and enclosure.
The Linearized models LSI-16 series are made available to monitor upto 16 channels, with +/1 oC or +/-0.1 oC indicating accuracy and larger display size.
The above models accepts 1 to 16 inputs but of single type only and having same measuring range. To suit applications where monitoring of different process parameters having different measuring ranges are required, the microprocessor based models are more suitable.
Microprocessor based Sixteen Channel Temperature Scanner /Data Logger model MSI-8000/DATALOG-16 are suitable for continuous monitoring of temperature/process variables at 16 different locations with the indicating accuracy of 1oC or 0.1 oC and for other process inputs the instruments offers absolute indicating accuracy. Each input has independent amplifier and hence each input can be of different type. For example, out of 16 channels, 8 can be thermocouples, 4 can be RTD (Pt-100) and rest 4 can be (4-20)mA.
Wherever, in addition to only monitoring the process parameters, the data logging, memory storage, common or individual high and low alarm relay outputs, printer or pc interface is also desired, the model DATALOG-16 offers them all as per the requirement. For this facility the built in real time clock allows real time data logging, parallel printer port allows on line and off line printing of the data and RS-232/RS-485 port allows data logging on to the PC. Necessary data logging software operating on Windows is also offered for both graphical and tabular representation of the data of all the channels which are logged in.
