With Perpetua products, you have the freedom to increase and vary sampling rates without having to sacrifice battery life. Increasing the sampling rates makes many types of sensing feasible that weren’t possible before.
MorePerpetua’s products are priced to break even on the first battery replacement. With lifetimes that match the products being powered, typical payback periods are short, total cost of ownership is favorable, and ROIs are high.
Battery changes are costly in terms of labor, storing replacements, and disrupting operations, and in general are a hassle in the sensor industry. Perpetua’s products remove the need for battery replacements.
MoreBecause of the limits of battery-powered sensors, many applications simply weren’t feasible previously, such as 1-second sampling rates for process pressure and temperature readings. With Perpetua’s products serving as renewable power sources, new applications in sensing, monitoring, and control are possible.
Update rates
The life of batteries powering wireless sensors is decreased as the data update rate increases. For many, running the update rates at the desired level results in unacceptably short battery life. This requires reducing the update rate and foregoing the benefits of more timely and robust data. Battery life is also shortened by high or low temperatures typical in industrial applications.
Using warm-to-the-touch surfaces, Perpetua's Energy Harvesters generate sufficient power to fully drive sensors at their maximum network update rates without sacrificing battery life. This allows users the operational benefits of having a more complete and timely picture of the equipment and processes being monitored for the full life of the sensor.
Battery
Sensor battery expense is only one component of the cost of replacing batteries in wireless sensor deployments. Typically, the storage and handling required for batteries as well as labor and operations disruptions associated with battery replacements are several times the battery costs. Over the life of the sensor, this cost represents substantial expense and erodes the benefits of wireless sensor deployments.
Perpetua's products are typically used in a "belt and suspenders" configuration with the energy harvesting energy used instead of the batteries but still having the batteries available as a backup if equipment is taken down for maintenance for example. This approach means that in all conditions the battery life will be extended and in most cases where Perpetua Energy Harvesters are supplying in excess of the sensor power requirements, the battery will effectively not be used and its life will be determined by its no-load storage life. Foregoing the need to replace sensor batteries over the sensor life creates major cost savings and eliminates battery maintenance hassles.
