Melt pressure transducer DS-series

KMK Melt pressure-
sensors DS-series

The melt pressure sensors of the DS series are most commonly used in plastic extrusion worldwide. The special membrane technology ensures maximum lifespan and provides reproducible measurement results. Depending on the type of melt pressure transducers, standardized output signals (1, 2, or 3.33 mV/V) are provided.

KMK's sensors operate based on the proven principle of strain gauge technology.

Exclusive use of mercury-free measuring medium
Very high quality standard
Titanium nitride coating to prevent adhesion of plastic melt
Pressure range from 0-100 to 0-1.500 bar
Connection: ½"-20 UNF-2A, M18 x 1.5, alternatively M14 x 1.5
Operating temperature up to 410°C at the membrane
Various special stem lengths
100% compatible with competitors

Melt Pressuresensors - Comparision

Melt pressure transducer DS1

Our melt pressure transducers are available in various shaft designs and optionally with a reinforced diaphragm made of 2.4610. As an alternative to the 6-pin standard connector, a fixed connection in various lengths with open cable ends can be selected upon request.

Melt pressure transducer DS2

KMK melt pressure transducers with flexible capillary. The capillary is protected by a robust protective spring, allows the transducer to be mounted flexibly in case of thermal radiation or limited space. The corresponding mounting part is included in the scope of delivery. Optionally, the sensor can be equipped with a reinforced 2.4610 diaphragm.

Melt pressure transducer DS3

Transducer in standard version with union shaft and exposed capillary. Optionally, the sensor is available with a reinforced membrane made of 2.4610.
