Intrinsically Safe Pickup Coil
Redi-Pulse IRP-101E
Intrinsically Safe Pickup Coil Redi-Pulse IRP-101E
OUTSTANDING FEATURES ♦ Intrinsic Safety to CSA (with NRTL/C), CENELEC and ATEX. ♦ Pickup coil includes a self-contained preamplifier which provides a conditioned pulse output. ♦ Both magnetic and modulated carrier pickup coils are available. ♦ Eliminates peripheral signal conditioning modules and associated junction boxes. ♦ Economical when compared to standard signal conditioning modules. ♦ Certified with CE mark for compliance with EMC Directive 89/336/EEC. ♦ Operates from DC voltage. ♦ Conditioned pulse output may be transmitted up to 5,000 feet. THEORY OF OPERATION The Redi-Pulse pickup coils are for use with turbine type flowmeters and include a self-contained preamplifier within the pickup coil housing. The pickup coil produces a conditioned pulse output which offers the benefit of greater noise immunity when compared to standard pickup coils. The incorporation of the signal conditioning module inside of the pickup coil itself eliminates the need for conventional signal conditioners that are meter mounted in a junction box, directly on top of the turbine flowmeter. The Redi-Pulse coil is available in both magnetic and modulated carrier coil versions. Turbine flowmeters specified with the magnetic coil will provide the user with a flow range with a 10:1 to 25:1 turndown ratio depending on meter size and type of bearings specified. Turbine flowmeters specified with the modulated carrier coil will provide the user with a usable flow range up to 100:1 when the turbine meter is specified with ball bearings. For additional information concerning performance specifications on the turbine flowmeters available from Hoffer Flow Controls, request the “Turbine Flowmeter Engineering Guide”.
