Acromag announces the first release from their new Vertu brand of
innovative instrumentation – the VPM3000 Series of universal input displays with transmitter
and alarm capabilities.
These instruments combine the digital indicator function of a panel
meter with optional signal conditioning for 4-20mA transmitter output and/or
alarm trip solid-state relays. The big and bright 31mm high numerals are
clearly visible from far away, even in bright sunlight. Field-selectable inputs
accept process current/voltage and temperature sensor signals including 4-20mA,
±20mA, 0-10V, ±10V, Pt RTDs, and most common thermocouple varieties. For
additional versatility, units can provide power to drive a 4-20mA transmitter
and other instruments. Modbus RTU serial communication is also supported.
Key features of the VPM3000 displays include easy set up and installation;
configurable using front-panel pushbuttons, free Windows software, or a copy
function from other units; models available for operation from 85-265V AC or 12-36V
DC power sources; AC units providing single or dual isolated 24V DC supplies to
power a 4-20mA transmitter or other instruments; shallow-depth 1/8 DIN
enclosure with NEMA 4X front panel simplifying installation; and UL/cUL listing
meeting industrial control equipment safety requirements.
These versatile signal conditioners can satisfy requirements for a
process or temperature transmitter, alarm trips and high-visibility display
with a single unit.
Also, advanced capabilities of the VPM3000 displays increase value. In addition
to converting sensor signals to a scaled 4-20mA current for retransmission to
controllers or recorders, units can also perform flow computation functions.
The square root function can linearize the signal from a differential pressure
transmitter to display flow rate in engineering units. A low-flow cut-off
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 pushbutton easily toggles display of min/max values. Dual relays
enable a variety of alarm trip configurations for high/low, high/high, and
low/low limit triggers.
Acromag’s new line of
panel meters can also be used for 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 your PC.
