Variable frequency drives are workhorses. In industrial and commercial facilities, they regulate motor speed, reduce energy consumption, and protect equipment from the stress of hard starts and sudden load changes. When one fails, operations feel it fast. At Omni Instrumentation & Electrical Services, our teams work across a wide range of facilities and electrical systems, and VFD issues are among the most common service calls we respond to. Over the years, we've seen the s

Control valves are workhorses of industrial process control, and when something's off, the effects ripple through your entire system. Here are five common issues worth having on your radar. Deadband (Hysteresis): Deadband happens when there's a lag between the control signal and the valve's actual position, often caused by backlash, excessive friction, or loose actuator connections. It can trigger oscillations in PI or PID loops and hurt system stability. Step tests or diagno

Omni was approached by a process engineer we'd previously worked with to investigate several challenges at a production facility under their management. The facility operated twelve 7,000-gallon process tanks, each equipped with double agitators, load cells, level transmitters, and temperature transmitters. The tanks handled a range of functions including mixing, heating, pasteurizing, storing, and transferring various liquid products, and the process engineer had been tasked

Every once in a while, a project comes along that truly stands out. As part of a larger scope of work, our client brought Omni on to support the instrumentation, controls, and commissioning of four large dry product storage silos, each standing 65 feet tall with a 75-foot loading platform. The system was designed to move dry product flakes at high velocity through 4-inch stainless steel piping, using blowers and specialized control valves to transport and deliver product with
