Pressure Transducers
QPress – QHT-TEMP 1100 Series
The QHT-TEMP 1100 Series is built for hot media, using a 316L-stainless isolation diaphragm to keep the sensor reading accurately where standard transducers drift. It measures 1 to 600 bar with a 4–20 mA output and a wide choice of process threads, suiting hot liquids and gases on process plant, steam and thermal systems. A rapid response and rugged stainless construction give a dependable pressure reading on the high-temperature points that usually need special handling.
