WIXOM, Mich. – Acromag in Wixom, Mich., is introducing the VPM3000 series of universal input displays with transmitter and alarm capabilities for manufacturing test and measurement and control applications.

These instruments combine the digital indicator function of a panel meter with optional signal conditioning for 4-to-20-milliamp transmitter output and alarm trip solid-state relays.

The 1.2 inch high numerals are visible from far away, even in bright sunlight. Field-selectable inputs accept process current and voltage and temperature sensor signals including plus-or-minus 20 milliamps, zero-to-10 volts, plus-or-minus 10 volts, Pt RTDs, and most common thermocouple varieties.

Units also can provide power to drive a 4-to-20-milliamp transmitter and other instruments. The devices also support Modbus RTU serial communication.

The VPM3000 displays are configurable using the front-panel push-buttons, free Windows software, or a copy function from other units. Models are available for operation from 85-to-265 volts AC or 12-to-36 volts DC power sources.

A shallow-depth 1/8 DIN enclosure with a NEMA 4X front panel simplifies installation. UL/cUL listing meets industrial control equipment safety requirements. Units also can also perform flow computation functions.

The square-root function of this test and measurement instrument can linearize the signal from a differential pressure transmitter to display flow rate in engineering units. A low-flow cutoff feature sets a user-defined threshold that forces the display to zero for slow flow rates that often produce unsteady output from a differential pressure transmitter.

A push button toggles display of minimum and maximum values. Dual relays enable a variety of alarm trip configurations for high/low, high/high, and low/low limit triggers.

They also can process on/off control and pump alternation applications. For desktop monitoring and data acquisition applications, the free software can display and log data from multiple meters on a PC.
