Processed parts must be electrically in contact with rack holding the parts. The maximum resistance allowable between the rack and the parts is 1.2ohms.
Number of circuits needed is 5
I would like a circuit designed out of commercially available components that will provide a red light when resistance being measured is >1.0 ohms and a green light when resistance being measured is <0.9ohms. The setpoint of each light should be adjustable over a range of 0.5ohms.
1. Power source GFI protected 120VAC 1 phase
2. Lights to be powered are LED - Flat Indicator Light, LED Lamp Type, 110VAC Voltage, 16mm Mounting Dia. Size Item # 24M175 Mfr. Model # 24M175 Catalog Page # 248 UNSPSC # 39121534.....Grainger catalog information
3. Circuit will be housed in damp environment
4. Test leads to connect to racks and parts will be standard test equipment test leads
