Gefran's wide range of sensors offer the ability to measure the primary process variables: position, pressure, force, temperature and humidity.
For example, the product portfolio for Melt pressure measurements includes:
     • mercury filled sensors for measurements up to 400°C
     • oil filled sensors (FDA approved) for measurements up to 315°C
     • NAK filled sensors (GRAS) for measurements up to 540°C
     • non filled sensors (IMPACT series) for measurements up to 350°C

In particular the IN and IE Melt pressure series is:
     • robust
     • reliable
     • modular
     • suitable for static and dynamic pressure

Moreover, the TR load cell family is specifically designed for plastic films tension control and a wide range of temperature sensors provides an accurate measurements for the control loop.
