Latest Patents
LaRoche's latest patents include the "Saturation-controlled loop current regulator" and the "Process fluid transmitter with an environmentally sealed service block." The saturation-controlled loop current regulator features device circuitry that generates values to be conveyed on a current loop. A series control transistor is positioned in series between the current loop and the device circuitry, while a saturation prevention circuit ensures that the series control transistor does not enter saturation. The process fluid transmitter incorporates an environmentally sealed service block, which is mounted inside a field wiring compartment. This service block includes field wiring terminals, sealed jumper assemblies, and sealed pushbutton switches connected to a sealed cable and plug. The sealed plug connects to a permanently sealed transmitter assembly, and the high impedance programming circuitry linked to the jumper assemblies and pushbutton switches is completely sealed, preventing malfunction due to contamination.
