Pressure transducers operate on the proven principle of strain gauge technology. The pressure is transferred from the measuring diaphragm (which is flushed with the melt channel) via a capillary system to a second diaphragm. The capillary system is filled either with mercury or with a mercury-free medium. The second diaphragm is fitted with a strain gauge. Using the linear change in resistance in relation to deflection, an electric output signal is provided. The special membrane technology guarantees a very long operating life, even under the toughest conditions. The anti-adhesion coating reduces the risk of damage caused by frozen plastic melts.
Our range of temperature sensors features proven thermocouple or resistance temperature measurement systems in a high precision but robust sensor. The Fe-CuNi (type J or L) thermocouples which generate a voltage when heated are well established in the industry due to their advantages thanks to the high Seebeck coefficient. For such applications, type K thermocouples are also available (NiCr-Ni). Additionally, our PT100 (2, 3 or 4-wire) resistance temperature sensors have resistance of 100 Ohm at 0°C which changes with increasing temperature. Conforms to EUROMAP 31.
