Time-stamped data provides valuable information for identifying and verifying past events. Harsh environments don't affect the reliability of our systems. Statistical and mathematical functions are built into our units, allowing data reduction at the measurement site. Each control unit has multiple channel types, allowing nearly all sensor types to be measured by a single unit. For example, one control unit can measure voltage, air velocities, air temperature, relative humidity, energy use, water temperature, and steam pressure, as well as solar radiation, external temperature, wind speed, and air quality.
Most sensors connect directly to the control units, eliminating external signal conditioning.
Multiplexers and other peripherals can be used to increase the number of channels and channel types. Powerful on-board instruction sets allow unattended measurement and control decisions based on time or conditional events. For example, alarms can be triggered, phone numbers dialed, or equipment shut down if a boiler's water temperature is outside the desired range.
