UTZ-P Penumatic displacer level transmitter fisher 2500
UTZ-P Penumatic displacer level transmitter fisher 2500
Fisher pneumatic controllers and transmitters are used wherever rugged, dependable, and simply constructed displacer−style pneumatic instrumentation is required in liquid level, interface level, or density service. The ruggedness of these products is demonstrated by their use in many kinds of demanding applications, including those in the power, chemical process, oil and gas production
Zero Adjustment (Transmitters Only) Continuously adjustable to position span of less than 100 percent anywhere within displacer length (fluid or interface level) or displacement force change (density) Performance Independent Linearity (Transmitters Only): 1 percent of output pressure change at span of 100 percent Hysteresis: 0.6 percent of output pressure change at 100 percent of proportional band, differential gap, or span Repeatability: 0.2 percent of displacer length or displacement force change Deadband (Except Differential Gap Controllers(3)): 0.05 percent of proportional band or span Typical Frequency Response: 4 Hz and 90−degree phase shift at 100 percent of proportional band, differential gap, or span with output piped to typical instrument bellows using 6.1 meters (20 feet) of 6.4 mm (1/4−inch) tubing Ambient Temperature Error: ±1.5 percent of output pressure change per 28 C (50 F) of temperature change at 100 percent of proportional band, differential gap, or span when using sensor with standard wall N05500 torque tube Reset (Proportional−Plus−Reset Controllers Only): Continuously adjustable from 0.005 to over 0.9 minutes per repeat (from 200 to under 1.1 repeats per minute) Anti−Reset Differential Relief (2502F and 2502FR Controllers Only): Continuously adjustable from 0.14 to 0.48 bar (2 to 7 psi) differential to relieve excessive difference between proportional and reset pressures
