4WPB100, 4WPB1K PRT Bridge

Terminal Input Modules

1. Function

Terminal input modules connect directly to the datalogger's input terminals to

provide completion resistors for resistive bridge measurements, voltage

dividers, and precision current shunts. The 4WPB100 and 4WPB1K are used

to provide completion resistors for 4 wire half bridge measurements of 100

Ohm and 1 killohm Platinum Resistance Thermometer (PRT), respectively.
