Dynisco LLC of Franklin, Mass., introduced two new products.
The SPX-T pressure sensor has a built-in RTD (resistance-temperature-detector) temperature sensor to provide more accurate readings.
With temperature compensation, drift in pressure readings from the impact of ambient temperature is reduced by as much as 80 percent, and the user does not need to reset the sensor after the process is brought up to temperature.
Temperature readings also can be linked to a controller display, giving the user the convenience of both pressure and temperature sensing in a single instrument.
Opt-Trol is a low-cost, modular polymer-melt-control system with a color, touch-screen operator interface.
Users can precisely control pressure and temperature on most extrusion lines. The unit offers adaptive, auto-tuned control of temperature, pressure and speed control, plus differential control and process-variable trend charts.
The temperature card was developed for single-screw, twin-screw, coextrusion or blow film extrusion.
A system can be configured with as few as eight zones, then expanded in increments of eight zones to a maximum of 80 zones of control.
