ECHO (NaK) Series
Dynisco's Echo Series offers quality performance through the use of standard configurations and pressure ranges. Echo pressure transducers are designed to meet customer requirements, provide a combination of economical choice and good performance for extrusion applications, while providing ± 0.2% repeatability when measuring process pressures. Echo sensors are the ideal choice for all processes and applications requiring measurement for optimized control.
Dynisco has been manufacturing pressure sensors for more than 60 years. The entire range is backed by a two-year full warranty. The membrane of ECHO sensors is coated with titanium, aluminum, nitride, already in the standard version, which offers better performance than less effective coating of aluminum titanium.
Dynisco technology is very popular with all OEMs and end users around the world. The Echo series is available with 3.33mV / V, 4-20mA, 0-5VDC or
0-10VDC outputs designed to work with most industrial controls. In addition to measuring melt pressure, the Echo series offers optional melt temperature measurement with J, K or RTD thermocouples. The Echo series is equipped with a 1 / 2-20 UNF or M18 thread for mounting in standard mounting holes. Additional mounting configurations are available.
