Introduction

This is a list of easily obtainable 4-20mA Loop Panel Meters for use with the 4-20mA transducer and Current transformer Bundles. This includes Loop Panel Meters compatible with the following Transducers and Transducer Bundle Series:

    • SCT-0400-XXXX-4-20B
    • SCT-0750-XXXX-4-20B
    • SCT-1250-XXXX-4-20B
    • SCT-2000-XXXX-4-20B
    • SCT-3000-XXXX-4-20B

    • UCT-0300-XXXX-4-20B
    • UCT-0500-XXXX-4-20B
    • UCT-0750-XXXX-4-20B
    • UCT-1000-XXXX-4-20B
    • UCT-1250-XXXX-4-20B

  • OSM-333-0420

Each of the transducer bundles is paired with a SCT or UCT series current transformer. This gives the total measurable current range from a custom load of 1A to a current load of 3000A or more. The current transformers are both solid core and split core and have a wide range of openings. The largest transformer has an opening of 3 x 5 inches.

List of Process Meters (Current Meters) 4-20mA Loop

The following is a list of Process Meters (4-20mA Loop) for use with the SCT and UCT series current transformer/transducer bundles. These Process Meters are used to measure current form a 4-20mA source. All of these Process Meters (4-20mA Loop) are panel mountable meters. All of these meters are easily obtainable and are generally in distribution with inventory

Although it is very common that a panel meter requires a loop supply some panel meter can be supplied from line voltage or an auxiliary AC source that is 120,240 or other. The Red Lion Controls PAX is an example of a panel meter that is capable of source in the 4-20mA loop current and being supplied by a source voltage of 85-250VAC.Â

Panel Meters Block Diagrams

There are two very typical topologies being use with process meter 4-20mA loop power current panel meters. The first topology is a process meter connected to a transducer and the loop power supplied by a loop supply such as a 24V supply as seen in the block diagram below. The second topology is a meter that connects to an AC voltage supply that has a self contained loop power supply. These supplies are the current source for the 4-20mA current loops.Â
