AC Motor Load Measurements

Many facilities have hundreds of motors installed throughout various processing units.  Monitoring of these motors for more precise control or protection is paramount. 

Petrochem facilities have hundreds of motors installed throughout various processing units.  Monitoring of these motors for more precise control or protection is paramount.  The model ECT is a Class I Div 2/Zone 2 DIN rail, loop-powered (two wire) signal converter with an operating range of -40 to 85C (-40 to 185F) that accepts AC current inputs of up to 0-5A AC and outputs a linear and noise free 4-20mA signal readable by the BPCS or PLC.  As an added safety feature, the ECT offers an optional externally mounted mini-CT (Current Transformer) that steps 0-5A AC down to 0-5mA AC  so technicians don’t have to worry about handling high current signals.  ECT also accepts high level AC voltage inputs too.     Key Attributes: -Two wire loop-powered AC signal converter  -Class I Div 2/Zone 2 approvals  -High ambient operating temperature range of -40 to 85C (-40 to 185F)
