The loop powered indicators are designed to display any process parameter like temp, flow,pressure,ph & others. These instruments accepts, 4 to 20 mA DC signal and generates the power from the signal it self. No external power or battery is required.The loop powered indicators are available in flame proof, weather proof, general purpose housing with wall mounting, panal mounting & 2" pipe mounting types. The CMRS certificates as per IS 2148 for flame proof versions are also available with the instrument. The state-of-the art of technology to display the parameter with high accuracy & linearity & low temp.Drift is employed. The range & decimal point are selectable on site with the help of DIP switch.
FEATURES
Range & Decimal point field selectable by DIP Switch.
The glass epoxy, Green mask with high quality component board is mounted on brass studs. The instrument is mounted on a MS plate & this plate with 2" U clamps are fitted on 2" pipe. DIP switch & LCD are visible from outside to adjust & read the ranges. Zero, span trimpots are accessible from outside for ON - line calibration for flame proof versions. The 4 to 20 mA signal generates the power for 1C, & a series resistance generating a voltage drop are fed to display the process parameter. The rangeability is added parameter. The rangeability is added with zero, span calibration trimpots.
APPLICATIONS
For local indication of process parameter in a huge plant Loop powered indicator is ideal since no power is required. These are used in steel, fertiliser, food, chemical, dairy, rubber & sugar industries.
