1 Introduction
The Model NK Portable Indicator is a battery-powered signal conditioner and
readout device. The Model NK provides precise electrical drive to a transducer
and translates transducer output into a digital display of engineering units.
The signal conditioner supports transducer outputs between 1 and 4 millivolts/volt
(mV/V); a high input option supports outputs up to 40 mV/V. The excitation supply
drives transducers with impedances as low as 250 Ohm at 4 volts. The readout
device is a 4-½ digit, liquid-crystal display.
Enclosed in a rugged, weatherproof aluminum case, the Model NK is specially
designed for remote field operations. Quick field setup allows the Model NK to be
used for a variety of applications, from checking the load on an oil well drilling bit
to determining natural gas line pressure.
