Casing wear is an increasingly typical problem that leads to a decrease in collapse resistance in deep wells, ultradeep wells, horizontal wells, and extended reach wells. Casing wear is an ...
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 ...
