The MM4420 provides a DC output voltage or current proportional to the quotient (ratio) of two DC inputs. Typical input ranges are 4/20 mA, 10/50 mA, 0- 1 V, 0-5 V, and 0-10 VDC. Other ranges are available down to minimum spans of 1 V or 1 mA DC. Standard calibration provides the output at full scale (100%) when both inputs are at full scale (100%). Other calibrations are available.
All Wilkerson products are designed with RFI filters and lightning protection to reduce susceptibility to electrical noise and damage by lightning.
TYPICAL APPLICATIONS
Controlling relative speed, mixing rates, compensating flow readings for temperature changes (mass flow = flow rate/temperature), etc.
