Models 202A-J, -K and -T are 3 1/2 digit ±1,999 count) panel meters for thermocouple types J, K and T. They are available for display in °C or °F and resolution of 1° up to 1,999° or 0.1° up to 199.9°. They are recommended for demanding indication-only applications where exceptionally low-cost is required. For display up to 1,999.9° with 0.1° resolution, Newport recommends its 2002B Series meters, which provides a 4 1/2 digit (±19,999 count) main assembly.

Standard Features
Newport's 202A Series thermocouple meters provide exceptional accuracy, as made possible by five-segment linearization and use of matched, graded components for each T/C type. Electrical features include cold-junction compensation and jumper selection of °C or °F. A 1 mV per count linearized analog output is standard and is ideal for driving a strip-chart recorder.

Mechanical features include a bright 0.56 in (14.2 mm) display, a screw-terminal barrier strip for signal and power, and a compact 1/8 DIN case that requires less than 4.1 in (104 mm) behind the panel. Electrical features include cold-junction compensation, jumper selection of °C or °F, and a linearized recorder output of 1 mV per degree.

Options
Options are isolated 9-32 V dc or 26-56 V dc power, a PCB edge connector for display control and output of +4.7 Vdc and -4.7 Vdc, and a splash-proof lens cover which meets NEMA-4 requirements.
