The KOBOLD NRF-1T are highly reliable and microprocessor based RF level sensors designed to measure tank levels of conductive and non-conductive liquids in metal tanks. The probe measures the change in capacitance that occurs as the tank level changes and outputs a standard loop-powered 4-20mA signal.

NRF-1T probes use very high frequency and very low amplitude sensing circuitry to greatly minimize the effects of coating on the sensing probe.

The NRF-1T includes a standard 4-20mA loop powered transmitter housed in a rugged enclosure, a rigid probe and a polished stainless steel Tri-Clamp® fitting. Probe material is SS316, supplied bare or PFA jacketed. Optional, remote mounted DIN Rail transmitter is also available, which can be connected to the level sensor via a 3-conductor cable up to 1000ft. long. This option provides ease of set-up when access to the probe electrical enclosure is limited. The calibration is accomplished via 4 push buttons, located on the transmitter. The series NRF-1T RF probe is truly designed with tough applications in mind.
