Dynisco's Vertex Mercury Free Pressure Sensors are now available with optional ATEX IS (intrinsically safe) approval, making them the first mercury-free sensor approved for use in hazardous environments. The latest Vertex are also available with new washdown compatible configurations.

Dynisco claims that its Vertex melt pressure sensor matches or exceeds the performance of the traditional sensor. According to the company, the big differences are that Vertex is more robust, much faster, and significantly friendlier to the environment.

The direct measurement tip is a simple design with a robust diaphragm. Direct measurement of the process reduces errors that are transferred by complicated internal support structures, transmission fill materials, or moving push rods. The diaphragm thickness is pressure range dependent and can be up to 7.5 times thicker than a traditional sensor, according to Dynisco. The sensor has a diaphragm composition of Inconel 718 coated with the abrasion resistant properties of DyMax®.

Vertex sensors are designed to work with universal pressure indicators. According to Dynisco, 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 adaptor 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 mechanical applications.

Dynisco is known worldwide for leading-edge pressure and temperature measurement and control products for the plastics extrusion industry. Dynisco specializes in developing solutions to address processing requirements of extrusion, molding, and process control applications. Among Dynisco´s early pioneering achievements was the first transducer to successfully measure melt pressure during the extrusion process.
