Digital promoters [india] pvt ltd, an iso 9001-2000 certified company, since 1979, produces wide range of industrial instrumentation. Strip chart recorders are part of those products. Strip chart recorders are microcontroller based for precision, convenience and flexibility. Salient features are as follows:
1. smps voltage power supply
2. polynomial based linearization for rtd, ma, mv and
3. thermocouple types j, k, r, s, t with software compensation for
4. cold junction temperature
5. software based mechanical calibration [pen alignment] for easy maintenance
6. stepper motor driven, pen and chart movement, the benefits of which are:
A. elimination of the need for mechanical feedback systems
I. and potentiometers
B. repeatable and enhanced reliability
C. reduction in maintenance
7. an optional digital display for continuous reading of parameter values and displaying messages
8. mechanical and electronic calibration done from front panel keyboard
