Kotron® RF Sensing Probes D E S C R I P T I O N Kotron RF Capacitance sensing probes are available in many different configurations to handle a wide variety of application conditions. The sensing probes in this brochure can be combined with Kotron level switches and transmitters. F E A T U R E S RIGID PROBES • Available as bare probe or insulated probe • Maximum process temperature: +1000° F (+540° C) - bare probe T E C H N O L O G Y +400° F (+200° C) - insulated probe The amount of capacitance developed in any application • Maximum process pressure 5,000 PSIG (345 bar) is affected by three variables: • Lengths up to 234 inches (6 meters) • size (surface area) of the probe; • Bare probes can be cut to length in the field • distance from the probe to its ground; • Wetted materials include 316/316L SS, Hastelloy C, ® ® ® • dielectric of the medium it is measuring. Teflon (TFE), Halar (ECTFE) and Kynar (PVDF) • Ceramic seals for High Temperature/High Pressure Considering that the probe’s mounting position is fixed, designs and the dielectric constant of the process media is stable, then the amount of capacitance developed is directly pro- FLEXIBLE PROBES
