Whats necessary for Viscosity Control?
All our circuit cards have either 0-4Vdc or 4-20ma analog outputs for monitoring or control. The output is viscosity and temperature in engineering units. To control, the analog outputs need to be input into a third party controller which outputs either a switch closure or an analog level for control of a proportional switch. There are literally hundreds of excellent controllers to choose among, easily procured for several hundred dollars. An excellent source for this equipment is Omega Engineering in Stanford CN.
