NRF-2 & NRF-3 - Capacitance Level and Temperature Transducer
Brand: KOBOLD Instruments, IncThe KOBOLD 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.
