February 20059-4 Features and SpecificationsM Series and TF Series Moisture Probes (cont.)Although the M and the TF Series probes may be installeddirectly in the process line, more often these probes are insertedinto a sample system. The sample system protects the probes andenables the user to easily remove the probes for calibrating,servicing and cleaning. Sample systems also control variousprocess and environmental conditions so that the moisture probeor sample system operates within specifications.The M and the TF Series probes, when operated with aBASEEFA-approved PM880, are intrinsically safe and designedto meet the requirements of IEC/CENELEC zone 0 areas.The M and TF Series probes measure moisture content in astandard range from -110°C to 20°C (-166°F to 68°F) dew/frostpoint temperature and optionally from -110°C to 60°C (-166°F to140°F). Both probes optionally measure temperature in a range of-30°C to 70°C (-22°F to 158°F). The TF probe optionallymeasures pressure from 30-300/50-500/100-1000/300-3000/500-5000 PSIG.Moisture Image Series ProbeThe Moisture Image Series Probe measures moisture,temperature (optional), and pressure (optional). The MoistureImage Series Probe has its own electronics module that consistsof a built-in microcontroller with 16-bit resolution.
