Math Computation Modules

Math computation modules are signal conditioning instruments that perform a wide variety of advanced transfer functions on sensor inputs and process current or voltage signals. The processed output signal is available as a scaled DC voltage/current output or frequency/pulse-width modulated output. Typical applications include calculating a sum, delta, average, flow rate, volume, weight, power, and other scaled or computed variables. The math/computation equations are entered into configuration software in a freeform format, the same as in most popular spreadsheet programs. A simulator screen provides instant feedback to test equations and see the output response before actual installation. Math Functions: • Add, subtract, multiply, divide • Square root, exponential (en) and power (Xn) • Logarithmic (natural and base 10) • Sine, cosine, tangent, and inverse • Absolute value • Minimum/maximum • Conditional arguments and Boolean logic (if, then, else, and, or, >, <, , =,<=,/>=) • Input scaling • High/low signal selector or discriminator • Track and hold For more information, watch our process automation products overview.
