Calculator for 4-20mA Signal to 1- 5Volt and PLC 16-bit Raw Count Values

The converter calculation involves converting analog signals, such as 4-20 mA currents, to meaningful digital values for a PLC’s 16-bit analog-to-digital converter.  For 4-20 mA to 1-5 volt conversion, the input current is mapped to an output voltage within a defined range. Then, the voltage is scaled to fit the 16-bit ADC range, accounting for …

Why 4 wire RTD’s measurement accuracy is better than 2 and 3 wire RTD?

RTD Measurement: An Overview  The Requirement for Compensation Benefits of 4-Wire RTD Measurement In comparison to the 2-wire and 3-wire configurations, the 4-wire RTD measurement configuration is clearly superior, principally because lead wire resistance is completely eliminated.  With a 4 wire RTD, resistance is not used to determine the temperature. The two lead wires of …
