TrueMelt To accurately measure extrusion pressures, Nominal Controls’ line of transducers reliably compensate for thermal zero shift, a phenomenon in which sensors detect pressures due to a change in temperature, rather than force.
What’s new? A new pressure transducer released late last year that supports pressures ranging from 0 pounds per square inch (psi) to 500 psi. Versions offered earlier top out at higher pressures of 1,500 psi, 3,000 psi and 5,000 psi.
Benefits Accurate pressure readings at temperatures of up to 750 degrees Fahrenheit, due to Nominal Controls’ thermal-zero-shift-error technology. Other transducers can produce false low-pressure readings due to thermal-zero-
shift errors at very high melt temperatures. Because of the accuracy of the transducers, users can better prevent rejects and waste.
