Panametrics Infrastructure Sensing aluminum oxide moisture probes have set the standard of performance and value in industrial moisture measurement for more than 40 years.
In use, 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 measure 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. Panametrics Infrastructure Sensing 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 -30 to 70°C (-22 to 158°F) and choice of five solid-state piezoresistive transducers are available to measure pressures up to 5,000 psig (345 bar).
Temperature and pressure input data are used by Moisture Image Series 1 and 2 and Moisture Monitor Series 3 analyzers to determine parameters such as parts per million (ppm) and relative humidity.
True Absolute Humidty Sensors
Film thickness of the oxide layer is critical to the performance of this type of sensor. Panametrics Infrastructure Sensing manufactures sensors with an oxide film thickness that causes them to exhibit true absolute humidity rather than relative humidity response. This critical film thickness also gives the Panametrics TF Series probe quick response and exceptional calibration stability.
Rigorous Calibration Standards Traceable to the NIST
The aluminum oxide sensor of each TF Series probe is individually calibrated in one of the world's most advanced moisture calibration facilities. Developed over several decades, this facility generates precisely known moisture concentrations, traceable to the National Institure of Standards and Technology (NIST), to which each sensor is exposed during the calibration process.
All data is gathered and stored by a dedicated computer system. Calibrations are repeated over a period of many months to ensure the stability of each individual moisture probe. Only those probes which meet Panametrics specifications for accureacy and stability are shipped to customers.
Panametrics TF Series probes are designed to be located at the process, exactly where the measurement is needed. Operating temperature is -110° to 70°C (-166° to 158°F). The probe can withstand pressures up to 5,000 psig (345 bar). No minimum flow rate is required.
In some cases, TF Series probes can be installed directly in the processs line. More often, to assure the integrity of the moisture measurement, a sample conditioning system is recommended.
Panametrics Infrastructure Sensing designs and manufactures a line of reliable, field-proven conditioning systems to meet the demands of most applications. If required, a special system will be designed to meet unique application demands.
