Description Honeywell's stainless steel 19C, 19U, and 19 Vacuum Gage Series sensors were developed for pressure applications that involve measurement of hostile media in harsh environments compatible with 316 stainless steel. The special Vacuum Gage Series sensors are specifically designed for applications that can be exposed to vacuum. The 19C Series are calibrated and temperature compensated. They are available for use with either a constant voltage or current source. They feature a variety of pressure connections to allow use in a wide range of OEM equipment. The 19U Series is uncompensated for applications that use their own specialized circuit designs. The 19C and 19U Series are rugged and reliable transducers for use in a wide variety of pressure sensing applications where corrosive liquids or gases are monitored.
