This calculator is based on the Sensor Total Cost of Ownership white paper (http://spaceagecontrol.com/s054a.htm). It allows you to compare the lifetime costs of ownership of two sensors or transducers.

Directions: 1. Enter values into all cells in the Assumptions section and press Set Assumptions. 2. Enter values in all remaining cells based on a quantity of 1 sensor. Then, press Calculate.

What Is The Purpose of This Calculator?

This calculator provides insight into what the lifetime costs are in purchasing, maintaining, storing, replacing, and otherwise using a sensor or transducer. The results from the calculator can often indicate that the initial purchase costs are just a small fraction of the sensor's lifetime costs. The calculator is a model only that is subject to the assumptions above as well as factors unique to your application.

The calculator does not address the time value of money.
