PT Series

PT130 | PT140 | PT150 | PT160 Hydraulic sensors

PT130 | PT140 | PT150 | PT160 Hydraulic sensors

PT130, PT140, PT150 and PT160 are designed to measure hydraulic pressure on injection molding machines. The PT series resists cyclic pressure and provides excellent performance even in demanding conditions. Changes in the hydraulic pressure profile indicate irregularities during the injection phases together with the performance of the forming operation and provide information on the stability of the overall system.

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

Ideal For High Temperature Processes

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.
