Libratherm offers digital temperature scanners, which are suitable for continuous monitoring of temperature or process values at different locations, hence eliminates the need for number of individual temperature or process indicators and hence saves on cost and panel space. The temperature is indicated within the accuracy of +/- 0.5% having 0.5 or 1 7-segment display along with the respective channel number at the adjustable scan interval of 2-20 seconds. The standard features includes scan/hold facility to either scan the channel or hold particular channel, and it can be incremented using the advance front panel membrane switch. Other than input from temperature sensors these models can also accept [4-20] ma or [0-5] volt signals to monitor other process variables like pressure, flow, ph, orp, ac voltage, ac current, etc. [4.4 to 4.6] : libratherm also offers microprocessor based temperature / process scanner model msi-80xx series, which is also suitable for continuous monitoring of temperature or process at different locations with higher accuracy and additional useful features of common and individual high or low alarms. Being microprocessor based it is more user friendly to operate. The model accepts thermocouples or rtd [pt-100] sensors, as inputs. The temperature is indicated within o o the accuracy of ± 1 c or ± 0.1 c of the specified input range, in spite of non-linear behavior of the standard thermocouple and rtd [pt-100] sensors.
The features of the digital & microprocessor based temperature scanners are:
Available in standard din sizes.
Digital and microprocessor based models.
Highly accurate and sturdy in operation.
Elegant looks and very easy to operate.
Accepts standard inputs like thermocouple, rtd - pt-100 2 or 3-wire input, etc.
