PT Series



The PT435A series of pressure transducers is the ideal choice for measuring high-precision polymer melt pressure in places where there is not enough space for a conventional sensor. The exposed part of the capillary allows a bend with a small radius of 3 mm and thanks to the special construction of the tip with a freely rotating nut simplifies installation and allows the use of Dynisco sensors even where it is not possible to install a standard sensor with a fixed rod or flexible capillary.

Standard transducers are supplied with a DyMax® coated membrane to increase wear resistance and long life. The 8-pin Bendix connector is used for easy connection and disconnection.

 All sensors in this series can be configured according to your needs. Contact us, we will be happy to help you.

High accuracy melt pressure transducer for space restricted areas

Our pressure sensors offer efficient, accurate, and durable solutions for reliable and safe pressure measurement. These sensors are used in a variety of industrial areas, where they monitor and measure the pressure of molten materials, ensuring optimal operation of production processes. Due to their resistance to high temperatures and pressures, which are typical for these applications, they represent a suitable choice for diverse uses. When selecting a sensor, it is important to consider the specific requirements of your application, such as temperature range, pressure range, and materials with which the sensor will interact. The correct choice of sensor guarantees reliable and accurate results and a long service life of the device without any problems. Installing the sensor into the mounting hole of the production line is simple.
However, if you have doubts about the proper installation, do not hesitate to contact our technicians. We are ready to provide support and offer the ideal solution for your application.
