The DPRn 427HT density sensor made of Hastelloy is ideal for sample temperatures up to 150 °C.The highly accurate sensor continuously monitors the product quality of liquids online during production.The temperature-compensated density or concentrations are calculated from the measured values.Depending on the sensor, these values are either calculated, displayed and processed by an Anton Paar evaluation unit or calculated inside the sensor and provided as a 4-20 mA signal.
