Loop Power Indicator

INTRODUCTION :

ANADIG LOOP POWER INDICATOR is a precision PROCESS INDICATOR to measure & Indicate current signal 4 - 20 mA from Two Wire TRANSMITTER. lt is SELF POWERED additional power source is not required, as power to the indicator is derived from Current Loop itself. A most versatile and Accurate Measuring Displaying unit for PROCESS PARAMETERS Such as TEMPERATURE, FLOW, PRESSURE, LEVEL, SPEED, % etc.

The Instrument is provided with jumper selection to achieve zero suppression or elevation. Both zero and span adjustable by multiturn Potentiometers, glass cover or accessible externally in flameproof W/P field mounting enclosures.

Enclosures :

Panel Mounting, Field Mounting, Flame Proof, Weather Proof Class MA, MB.

Field Mounting :

The cast ALUMINIUM weatherproof or flameproof housing is wall mounting type for which 2 Nos. Mounting holes are provided on the base of the casting for field mounting.

Installation & Wiring :

Unscrew the bottom cover the three Terminal will be visible. First two Terminals are marked as + & - these two terminals are used as current input from two wire transmitter. This current input signal also acts as a power to the instrument. The Detail wiring is given separately.
