Characteristics of the Mercury Free Series
Pressure sensors of this series are sensors with mercury-free filling in the form of oil, NaK or special construction without filling. The most common uses are food, packaging or pharmaceutical applications. If you were used to taking sensors from another series and you were obliged to use mercury-free cartridges, it is also possible to equip standard sensors with an optional configuration - B171 - mercury-free cartridge.
Contact us, we will be happy to help you with the configuration.
ECHO (NaK) Series
Mercury-free. Trusted for Quality, Reliability and Accurate Performance at an Affordable Price
Dynisco's Echo™ Series of melt pressure sensors offer quality performance and value for plastic processing utilizing standard configurations and pressure ranges. Echo sensors are designed to meet customer requirements by providing a combination of economic value and performance for general extrusion applications while providing a ±0.2% repeatability when measuring process pressures. Use Echo Series sensors when the application requires a quality measurement for optimized control, but not the costs of all the extra features.
