Omega introduced its new series of rangeable, very low differential pressure transmitters which can output either static (gage) pressure or differential pressure. The PX2600 series has four unidirectional and four bi-directional ranges, three selectable outputs (0 to 5 Vdc, 0 to 10 Vdc, 4 to 20 mA 2-wire), pushbutton or remote zero, and four-digit LCD with the ability to show either static or differential pressure.
Veris Industries has introduced the E5xxxA Series to its line of power and energy meters. The company says the series combines the metering performance expected from the traditional E5x family with the addition of a built-in integrator and power supply for the needed rope style CTs.
