The DP302-J, -K and -T are 3-1/2 digit (±1999 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 1999° 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 1999.9° with 0.1° resolution, OMEGA?. recommends its DP3002 Series meters, which provides a 4-1/2 digit (±19,999 count) main assembly.
STANDARD FEATURES
The DP302 Series thermocouple meters provide exceptional accuracy, as made possible by fivesegment 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 14.2 mm (0.56") display, a screw-terminal barrier strip for signal and power, and a compact 1/8 DIN case that requires less
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 to 32 Vdc or 26 to 56 Vdc 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 (IP65) requirements.
