Pressure Transducers
QPress – QST-HIGHTEMP 5200 Series
The QST 5200 Series is a high-temperature pressure transmitter for hot liquids and gases, rated for media up to 150 degrees C without an external cooling element. It reads gauge ranges to 1600 bar at ±0.25 % FS with a 4–20 mA output, and the IP65 housing on an M20x1.5 waterline seal suits steam, thermal-oil and hot-process duty in chemical, petrochemical and power plant. It holds a stable, accurate reading where heat would compromise a standard transmitter.
