The KOBOLD series NRF-2 and NRF-3 combination level and temperature transmitters are truly a unique product. They are designed to measure level and temperature of conductive and non-conductive liquids in tanks. For level sensing, the probe measures the change in capacitance that occurs as level changes in the tank. For temperature sensing, the probe utilizes a platinum resistive element. The NRF-2 includes a loop powered transmitter for both level and temperature while the NRF-3 includes a loop powered transmitter for level and a 3-wire RTD output. A choice of rugged enclosure types with either standard NPT or optional Tri-Clamp® process connections are offered. The standard probe material is PFA clad 316 SS. Easy level calibration is accomplished via 4 push buttons with temperature calibration adjustment (if required) via two potentiometers located on the transmitter.
