Description:
Libratherm offers large display digital temperature/process indicator to monitor the temperature/
process value from long distance or height. The design is based on Analog and Digital circuit using 3 and
½ digit DPM or 4 digit DPM and 7 segment LED display modules.
The indicator is housed in a sturdy powder coated metal enclosure and can be mounted on wall or on
ceiling or on the shelf at a height. It accepts factory set thermocouple, Pt-100 or universal analog signal
of 4-2mA, 0-20mA, 0-5VDC or 0-10VDC which can be scaled and calibrated as per user requirement in
the range of 0 to 1999 or -1999 to 1999 or 0 to 9999 or -1999 to +9999 counts.
