Pressure sensors

Vertex - Mercury-free melt pressure sensor in a different type of construction.

Vertex Series

Dynisco’s Vertex melt pressure sensor innovation matches or exceeds the performance of the traditional sensor. The big differences are that Vertex is more robust, much faster, and significantly friendlier to the environment. The direct measurement tip is a simple and elegant design with a more robust diaphragm. Direct measurement of the process reduces errors that are transferred by complicated internal support structures, transmission fill materials, or moving pushrods. The diaphragm thickness is pressure range dependent and can be up to 7.5 times thicker than a traditional sensor. Add to these features, a diaphragm composition of Inconel 718 coated with the corrosion and abrasion resistant properties of Dymax® and experience the true definition of a robust sensor that has proven to increase the life of the sensor and significantly lowers the cost of ownership. Vertex design innovation also extends to the speed of response of the sensor. Faster processes and controls demand faster sensing measurements. Vertex is many times faster than traditional sensors improving real-time production.

Environmental regulations and community conscientiousness are driving sustainability policies and programs in large and small companies. Waste stream reduction and longer life cycles are good for the environment and the budget. There is no mercury, no NaK, no oil, no Gallium, no fill material what-soever. Vertex is also RoHS compliant. Vertex sensors are designed to work with universal pressure indicators. HART digital communication is available for more extensive diagnostics and remote configuration. An optional Type J or K thermocouple is available to provide a melt temperature signal as well as a 4-20 mA temperature output. Vertex is equipped with a 1/2-20 UNF for installation in standard transducer mounting holes. An adapter is also available to install 1/2-20 UNF units into a Button Seal application. A sealed welded shell and electrical connection are available if washdown capability is needed for food or medical applications (not available if thermocouple option TCx is selected).

A New Standard in Durability, Environmental Safety, and Reliability

The pressure range for Vertex is now available from 250 - 10,000 PSI.  Vertex is more accurate within our Polymer Test  equipment than any other mercury-filled sensor and is ideal for industrial applications that require low pressure. Not only is this an overall improvement to one’s process, but it helps with customers that are focused on sustainability and zero-waste. 

Vertex Series - With rigid stem


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.

Vertex Series - With rigid stem and flexible capillary


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.

Vertex Series - Combined sensor with rigid stem, flexible capillary and built-in temperature sensor


Combined 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.

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.
