Loop Powered Indicators

We are dealing in loop powered indicators, 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.

Loop Powered Indicator

GENERAL DESCRIPTION

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.
	No need of external power.
	High accurancy & linearrity and low voltage drop.
	Flame proof, weather proof, Genaral purpose versionsavailable.
	High accuracy & linearity.
	Low loop voltage drop.

CONSTRUCTION & OPERATION

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 avoltage drop are fed to display the process parameter. The rangeability is added parameter. The rangeability is added withzero, 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.

GENERAL DESCRIPTION

Signal isolators are used to provide isolation between both field DC signals and final control element. The instrument provides 1.5 KV DC galvanic & opto isolation between the input signal & output signals. These instruments accepts 0/4 to 20mA singal proportional to input.The high accuracy, linearity & very low temp. drift is the added feature. The instrument is housed in a std DIN rail housing with zero, span adjustments are user accessible.The instrument in packaged in plastic DIN rail also suitable for wall mounting. 24v DC output is optional to power field transmitters.Dual I/P & Dual 0/P version available. Also 8 I/P and 8 O/P version in DIN rail mounting available. Any I/P & O/P configuration as per system requirement can be given.

FEATURES

Eliminates ground 100 P problems.

Duel l/P-Dual O/P, Four I/P- Four O/P versions available. Also 81/P-8O/P version available.

All I/P-I/P, I/P-O/P & O/P-O/P isolation (Threeport isolation)
