I recently contributed a design for a simple platinum resistance temperature detector (PRTD) resistance two-wire 4-20mA transmitter circuit illustrated in Figure 1. Figure 1 A two-wire, 4 to 20 mA ...

The temperature coefficient of resistance (TCR), also referred to as RTC, is a performance characteristic that is heavily influenced by resistor construction for very low resistance values and can be ...

Twelve volts was a big deal when domestic manufacturers adopted it in the '50s. Doubling their voltage from 6 made electrical systems comparatively efficient and the increased power ushered in a new ...
