1/2 DIGIT PROCESS RECEIVER
MODEL 2002B-P / 3002-P Option -E Process meter with Transmitter Excitation
Model 2002B-P is a low-cost, high-resolution 4 1/2 digit panel meter for process signals that require zero and span adjustment for readout in engineering units. The resolution is 1 part in ±19,999 counts, or 0.005% of full scale. Accuracy is up to 99.98% of reading. The 2002B-P can be used in ratiometric pot-follower applications to determine liquid level or valve setting from the position of a potentiometer wiper. The required external reference voltage can be derived from the meter's own 4.7 V dc supply. The 2002B-P is housed in a short 1/8 DIN case that requires less than 4.1 in (104 mm) behind the panel. A screw-terminal barrier strip is standard for signal and power. Options include isolated 9-32 V dc and 26-56 V dc power. A splash-proof lens cover which meets NEMA-4 requirements allows the 2002B to be used in harsh industrial environments. SPECIFICATIONS ANALOG INPUT
