Mighty Module MM4431 DC Input Expotentiometer Transmitter

MM4431 DC Input Expotentiometer Transmitter Output = Y=X^m

Mighty Module,MM4431,DC Input,Expotentiometer,TransmitterDescription

The MM4431 provides a DC output voltage or current proportional to the exponent (M) of the DC input. Typical input ranges are 4/20 mA, 10/50 mA, 0-1 V, 0-5 V, and 0-10 V DC. Other ranges are available down to minimum spans of 1 V or 1 mA DC. The exponent M can be any value between 0.2 and 5. This range covers the most common requirements for measuring differential pressure in flow applications such as encountered in orifice plate or pitot tubes. The range of M also includes the ranges used to provide flow data from Parshall flumes and V-notch weirs. In a Parshall flume, the flow is related to the height of the liquid level by the 3/2 power of the height. In a V-notch weir, flow is related by the 5/2 power to the liquid height. The module includes filtering and conditioning to reduce susceptibility to transients and noisy operations.

Mounting

The MM4431 is designed to plug into a standard 8-pin relay socket. Part number MP008 is a molded plastic socket suitable for mounting on a flat surface or in a 2 3/4 inch wide PVC snap track (TRK48). Use CLP-1 hold-down clip, if needed. A Killark HK Series explosion-proof housing with dome and 8-pin socket is available (HKB-HK2D-8).
