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. Echo was designed with the best engineering practices and is backed by Dynisco with two full years of warranty - double the protection of comparably-priced sensors. Echo sensor diaphragms are coated with Titanium Aluminum Nitride, as a standard offering, providing superior performance over less effective Titanium Nitride coatings. Dynisco technology is widely accepted by OEM's and end users throughout the world. The Echo Series sensors are available with 3.33mV/V, 4-20mA, 0-5VDC or 0-10VDC outputs designed to work with most industrial controls. In addition to melt pressure measurements, Echo Series offer a optional melt temperature measurement with type J, K thermocouples or RTD. The Echo Series are equipped with a 1/2-20 UNF or M18 thread for installation in standard transducer mounting holes. Additional mounting configurations are available.

Rigid Stem pressure sensors are easily installed into the mounting hole of the production line, ensuring a simple and robust design that is suitable for applications where the sensor is not exposed to radiant heat from the line and the electronics are not subjected to extreme temperatures. We do not recommend installing these sensors in a vertical position above the line (12 o'clock position), as radiant heat can negatively affect the sensor's electronics lifespan. In such cases, we recommend using a sensor design with a flexible capillary, which allows the electronics to be diverted away from the radiant heat, ensuring a long sensor life. The main advantages of this type of sensor include resistance to impacts and vibrations, enabling them to withstand mechanical stress, which increases their lifespan and reduces the need for maintenance. They also feature high accuracy, ensured by quality materials and advanced measurement technology, which is crucial for efficient process control.
Pressure sensors with flexible capillaries represent a professional solution suitable for applications with limited space or exposure to radiant heat from heating elements in production lines. Thanks to the thoughtful extended design, the sensor's electronics are located out of reach of the radiant heat source, reducing the risk of damage.
The flexible capillary is designed to be resistant to damage and allow a high degree of bending, which facilitates installation and handling of the sensor. It is essential to properly secure the sensor head to the included adapter, which is part of the package. To achieve optimal performance, we recommend placing the adapter on a part of the machine where unwanted vibrations or shocks do not occur, as these could negatively affect the sensor.
The length of the rod and flexible capillary can be customized according to individual needs, as well as other optional components. This ensures maximum flexibility in integrating the sensor into a wide range of industrial applications.

Additionally, these sensors are equipped with a temperature sensor, allowing the customer to choose the type of sensor, whether it is a type J, K thermocouple, or an RTD (pt100). By selecting a compatible sensor for temperature measurement, the customer obtains information about the melt temperature from a single process connection, increasing measurement efficiency and accuracy.

*Accuracy is defined as the combined error expressed as a percentage of full scale output. Combined error includes linearity (BSL), as defined in ISA-S37.1. **To avoid bending a 6" snout using a 12" wrench, do not apply more than listed torque without supporting bending moment. When applying torque to a snout longer than 12", counteract the bending moment with a support.
