TF Series - Aluminum Oxide Moisture Probe

main-TFprobe-alum-ox-moist

TF Series probes are coupled to Panametrics hygrometer consoles by an interconnecting cable. Ease of use, wide measurement range and rigorous calibration standards make these systems the preferred choice for industrial moisture measurement worldwide.

 

Built-In Pressure and Temperature Measurement

The three-function TF Series probe measures pressure and temperature, in addition to moisture content. This is because accurate determination of many moisture measurement parameters requires knowledge of the process temperature and pressure. GE eliminated the inconvenience and limitations associated with installing and using separate temperature and pressure sensors by building that capability directly into the TF Series probe. A nonlinear negative temperature coefficient (NTC) thermistor to measure temperature from –22°F to 158°F (–30°C to 70°C) and a choice of five solid-state piezoresistive transducers are available to measure pressures up to 5000 psig (345 bar).

 

Temperature and pressure input data are used by Moisture Image Series 1 and 2 analyzers, Moisture Monitor Series 3 analyzer and PM880 portable hygrometer to determine parameters such as parts per million (ppm) H2O and relative humidity.
