Campbell Scientific's measurement and control systems optimize HVACR system performance, conserving energy and cutting costs. Like typical HVACR control systems, our systems measure certain parameters and control equipment based on those measurements or based on time.

Our systems feature many capabilities that surpass those of standard systems and offer more flexibility for matching systems to exact needs.

In a typical HVACR application, sensors monitor relative humidity, flow rates, temperature (indoor and outdoor), differential pressures, and equipment status. Almost any sensor may be used with the system, allowing customization for each operation. Each of our control units features a variety of channel types for flexibility in measuring many different types of sensors. Types of common measurements are listed below.

Based on the measurements and the desired outcome, the control units actuate proportioning valves, boilers/heat exchange units, pumps, blowers/air handlers, shutters and other devices required to bring building(s) to the desired state. In case of equipment failure (or other measured event), the system sounds alarms or calls out on a phone, radio, cellphone, or other device. Data can be stored and/or transmitted to an on-site or central computer.

External conditions can be monitored using our meteorological sensors, or simple thermocouples can be used to provide temperature references.
