The newest addition to Acromag’s Vertu™ brand of innovative instrumentation is the VPM2000 Series of loop-powered display meters with process current output and alarm capabilities. These instruments supplement the digital indicator functions of a panel meter with optional 4-20mA isolator output and/or alarm trip solid-state relays. A dual-line LCD display has large 0.7 inch digits, an optional bargraph, and a backlight for clear visibility in bright sunlight or dim lighting. The backlight glows red and flashes under alarm conditions. No separate power supply is required for easy installation almost anywhere. They are even UL/cUL approved for use in hazardous locations requiring intrinsically safe, non-incendive devices.

The VPM2000 displays are simple to set up and install. USB connection to a PC makes setup fast and easy with the free configuration software which can save the file for copying to other units. Front-panel pushbuttons can also set operating parameters and serve as function keys to change the display or acknowledge alarms. A shallow-depth 1/8 DIN enclosure with a NEMA 4X IP65 front panel facilitates mounting. Internal PCBs are conformal coated for protection from the elements while a -40 to 75°C operating range enables use in extreme environments.

“These versatile instruments combine the functionality of a 4-20mA signal isolator, a dual-relay limit alarm, and a digital display in a single unit that is powered off a process current loop” explains Robert Greenfield, Acromag’s Business Development Manager.

Other advanced capabilities add further value. Two open collector outputs and a digital input are standard. The discrete outputs are useful for alarm indication or pulse output. The discrete input can trigger or reset alarms. Square root, exponential, and linearizer calculations perform scaling for flow and volume computation. The two-line display can show the measured process value in different scales such as tank height on the top line and volume on the bottom. Pushbuttons toggle display of min/max values or other units. Dual relays enable a variety of alarm trip configurations for high/low, high/high, and low/low limit triggers. Relays can also be used for process on/off control and pump alternation applications with display of runtime and cycle counts.

Acromag, a mid-sized international corporation, has been developing and manufacturing measurement and control products for more than 60 years. They offer a complete line of industrial I/O products including process instruments, signal conditioning equipment, data acquisition boards, distributed I/O systems, and communication devices.

Condition monitoring of critical components on machines delivers enormous benefits to productivity in a plant.  Rather than have a motor, pump, or compressor unexpectedly fail and the machine be inoperable until a replacement part is installed, condition monitoring of those critical pieces on the machine can provide warning signs that something is about to go terribly wrong. Vibration measurements on rotating equipment can detect when there is imbalance or degrade on rolling bearing elements.

Unplanned downtime threatens productivity and profit across industrial and commercial sectors. In a recent survey of these customers, 20% rate reaching zero unplanned downtime as their top priority, and 70% consider it a “very high priority.”

 Often, downtime comes as a surprise because facility operators lack visibility into their operations. Hardware failures and malfunctions account for 45% of downtime incidents – but 71% of field service decision makers aren’t fully aware of their assets’ maintenance schedule.

Those of you in the food industry are already familiar with the Food Safety Modernization Act (FSMA)—a law that focuses on preventing contamination, rather than reacting to the problem after the fact. A big part of FSMA compliance has to do with the design of plant equipment, which includes the electrical components that provide power to manufacturing lines.

Fortunately, MENNEKES offers a variety of electrical products that make FSMA compliance easier than ever. Let’s explore this topic in our new blog post.
