Pressure sensors

The Cavity Eye newly developed more precise, durable, water and shock resistant sensors are available. The company offers sensors in different diameters (15 and 26 mm), which have a maximum load range of 1 to 40 kN.

The pressure sensors operate on an electro-resistive principle, which is one of the oldest and most stable measuring methods. Cavity Eye uses only indirect sensors. From our experiences, the indirect measurement is much more precise, than the direct measurement. Using indirect measurement results in no need for sensor maintenance during the whole lifetime of the mould. Thanks to the sensor geometry we designed, the sensor installation is as easy as it gets! The final form of the sensors was achieved with years of hard work and development, so you get the most reliable source of information about your mould.

The brand name of the new type sensor is RC, which refers to Ring Cell because the sensors have a rubber ring around the diameter of the sensor which is aiming to help the following:

  • Simplify the mould modification process
  • Eleminate the fitting problems caused by the radius of the bottom of the sensor pocket
  • More precise positioning of the sensors inside the pocket
  • Enables smaller manufacturing precision and larger tolerances

The sensors are grouped by dimension and maximum load. The colour code of plastic pipe on the sensor cable refers to the type of the sensor:

15 mm diameter (RC15):

  • 1 kN load (red pipe)
  • 5 kN load (gray pipe)

26 mm diameter (RC26):

  • 20 kN load (red pipe)
  • 40 kN load (gray pipe)

RC15 Pressure sensors

Up to 5 kN

RC26 Pressure sensors

Up to 40 kN

Every sensor type has an item number, for example RC-15-1— where RC refers to the type of the sensor, 15 refers to the diameter of the sensor in mm and the last number refers to the maximum load: 1 kN. The possible two characters at the end of the code refers to the operating temperature of the sensor. For every different maximum load, there are higher temperature range sensors. The older PC sensors has medium-temperature variation (MT code), which is capable of measuring up to 150°C, while the new RC type normal sensors can be operate up to 150°C by default. Every sensors has a high-temperature range variation (HT) which is capable of measuring up to 200°C.

Please note that we are not distributing the older PC type sensors, the PC type sensors in the table are only for information purposes. The following table helps You in choosing the right sensor for your mould.

Mould Plug with Memory

The Cavity Eye Mould Plug with Memory (MPM) socket was developed for the Injection Moulds equipped with Cavity Eye pressure sensors. This socket is equipped with a special, integrated memory, and responsible for storing the data of the moulds and the Cavity Eye sensors. The wiring of the sensors takes place in this device, and it is also the counterpart of the Cavity Eye Smart Measuring Plug (SMP). This socket is equipped with a special, integrated memory, and responsible for storing the data of the moulds and the Cavity Eye sensors. The memory can also contain the production data of the mould, for example: reference curves, tolerances, pin diameters, cavity IDs, etc.

There are two types of Mould Plugs you can choose from, depending on how much sensor signal is required to handle. MPM8-B type can be used up to 8 sensors. Over 8 sensors and up to 16 sensors 2 MPM8-B device can be applied. In case of higher sensor number, the MPM32-A device can be used. It can handle 32 sensors at the same time. In case of using more, than 32 sensors but maximum 64 sensors, 2 MPM32-A device is the right choice.
The production starting and restarting procedure is getting quicker and easier with the memory in the MPM. You only have to upload memory content once, and the mould can be transferred to any injection machine afterwards, because the information is moving with the mould.

The following table helps You in choosing the right MPM socket.

Mould socket with integrated memory and offset spacer (MPM8-B-OS)

Mould socket with integrated memory (MPM32-A)

Up to 32 sensor channels
