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.

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.
