Pressure measurement system DMS

Pressure measurement system – optimizes the filling process

Let’s start with the main features:


  • Compact add-on device
  • for 4 to 32 zones in steps of 4
  • Additional analogue input 0-10V
  • Operation via hot runner control devices
  • Flexible visualisation  

A winner in combination with the hot runner controller

Since 2018 in our assortment the pressure measurement system DMS boasts high filling study precision and enables optimum cycle times during the filling process. The automatic detection of good / bad parts ensures a high degree of automation. The pressure curve indicates whether the temperature for melting the raw material should be increased or reduced in order to achieve an optimised filling of the cavity. The settings for the mould cavity pressure are stored in just one mould data set. The visualisation occurs via the connected temperature controller. DMS can be used irrespective of the sensor brand.

Sensor cable

Customer-specific manufacturing pressure cable for connection the pressure measurement system to the mould

Possible combinations:


All device data and mould settings can be centrally stored and managed via the Ethernet connection. Furthermore, additional devices such as needle valve-control NVS and pressure measuring system DMS are linked with the devices via the Ethernet connection. These then perform the operation and visualisation. Various injection moulding machines can be connected via conventional data interfaces or via the Ethernet so that operation and visualisation occurs on the machine’s screen.
