PA1001A Series of Preamplifiers: These preamplifiers are offered in configurations that provide the capability to work with both VR, RF or a combination of both types of sensors. Some of their noteworthy features are: near zero sensing capability, ability to sense very low signal levels, rejection of unwanted noise and spurious signals, user-definable pulse outputs, and optional features such as analog output, pulse scaling and linearization.

PA2001 Series of Preamplifiers: These preamplifiers combine many of the fine features of the PA1001A series in a low cost, compact unit intended for mounting in an elbow condulet box such as Crouse Hinds Model LBY15. Versions are available in either combination VR/RF or VR only.

PCA121S Digital to Analog Converter: A convenient and low cost device that will provide current and/or voltage based analog output from pulsed signals to drive plotters, recorders, printers and other data acquisition equipment. Its intended use is with MSI – or other company's - sensors, preamplifiers and other devices that produce digital, pulsed output, when analog output is desired. It can be used, for example with our Digi-Pulse, Hall Effect and Magnetoresistive sensors, and our PA2001 preamplifier. It can also be used with our intrinsically safe products when it is mounted on the "safe" side of the barrier.
