Princo Instruments, Inc., has reduced the price on its L3610 NULL-KOTE� analog RF Level Transmitters.��

The new price, at $995, makes these units the most competitive high-stability, high-accuracy, universal RF level controls on the market with FM approval.��

Adding to their versatility is the fact that they can be field configured to measure the level of virtually any process material � from low dielectric materials such as refined oil to highly conductive slurries.��

Such a wide range of applications often has proved troublesome for many RF instruments.��

The L3610 transmitter is a high sensitivity, extremely stable instrument, with proprietary enhanced NULL-KOTE� circuitry� --� providing accurate readings even when conductive materials build up on the sensing probe.� Other novel features include RF immunity, exceptional temperature stability, conformal coated circuit boards, factory pre-calibration, and built-in self-diagnostics.� These level transmitters are FM-approved for Class I, II, III, Div. 1, Groups C, D, E, F & G/NEMA 4 and are provided with Princo�s unique 10-year warranty.

���� FM approval helps extend the applications suitability of the transmitter in both hazardous as well as non-hazardous areas.� This is because users report that the process in a non-hazardous area may change, and users want reassurance that the equipment purchased today will not be obsolete should the process change.

���� The transmitters are easily calibrated using non-interacting zero and span adjustments.� The universal design allows the user to re-configure or re-range the transmitter in the field.� Built-in diagnostics provide assurance that the system is operating properly.

���� The L3610 provides a standard 4-20mA dc signal that is proportional to the process level, and is field convertible for a reverse span of 20-4mA.� A variety of sensing probe designs is available, including Teflon and Kynar sheathed rigid probes and cable-type flexible probes.

���� Princo has designed the L3610 with features that speed and simplify installation, such as the probe and electronics in a single, integral unit; "easy-on" sensing probes that self connect without the need for special tools or trouble-prone connectors; readily accessible, top-mounted, clearly-marked terminals with plenty of wiring room; and pre-calibration at the factory at no extra cost.� Other standard features that many manufacturers charge extra for include an explosion-proof, weather-proof NEMA 4 enclosure, and ruggedized, conformal coated ("tropicalized") electronics.
