MDA Series

MDA435 - Melt pressure sensor with flexible and exposed capillary


The MDA435 models are robust and reliable sensors. These models are equipped with a flexible and exposed capillary for easy installation and use in extremely cramped conditions or deviation of the sensor measuring head from the radiant heat of the machine.

The entire MDA range provides an industry standard with a 3.33 mV/V output signal designed to work with most pressure indicators and regulators. This sensor model is equipped with an eight-pin Bendix connector and a 1/2 "-20 UNF 2A or M18x1.5 mounting thread.

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

High Accuracy, Simple Installation, Repeatability And Reliability

Special sensor for confined installation spaces or injection applications.

MDA435 Pressure Sensors - With flexible and exposed capillary

Innovative pressure sensor, perfectly designed for injection applications with minimal installation space. Thanks to its unique features and state-of-the-art technical parameters, this sensor can cope with demanding conditions in any environment. The manufacturer spared no expense in advanced technologies and sophisticated production processes, enabling the sensor to achieve very small dimensions and low weight without any compromise to its outstanding performance. The pressure sensor is an ideal solution for a wide range of injection applications, thanks to its exceptional resistance to vibrations, which it can withstand very well. A pleasant bonus is the easy and hassle-free installation of this sensor in spaces with limited dimensions.
