Pressure is a critical process variable that needs to be measured and controlled. Gauges report how much pressure is being generated. Differential pressure switches offer proof that a pump or fan is working. Transducers convert pressure into a signal sent to a controller to manage the pressure at the production source. Relevant Solutions offers many devices to measure and control pressure for both commercial and industrial applications, with products from many manufacturers including ACI, Dwyer, Honeywell, INTEC Controls, Johnson Controls, Setra and Veris.
