Food Extrusion Pressure Transducer 

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.

PT415D Pressure Sensors - 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.
