Selection Guide
Output Selection
Choose 4-20mA for runs over 10 feet or in electrically noisy environments. Use mV/V only for legacy systems.
Stem Length
Match stem length to barrel wall thickness plus 1". Standard barrels use 6"; large machines may need 12".
Pressure Range
Select range 20-30% above your normal operating pressure. Running at full scale reduces sensor life.
Brand Cross-Reference
½-20 UNF is universal across Dynisco, Gefran, Omega, Kistler, and most OEM extruder brands.
