The DP3002-J, -K and -T are low-cost 4-1/2 digit (±19,999 count) thermocouple meters with 0.1°C or 0.1°F resolution for indication-only applications. High accuracy is provided by five-segment linearization and matched, graded components for each T/C type.
STANDARD FEATURES
Mechanical features include a bright 14 mm (0.56") display, a screw-terminal barrier strip for signal and power, and a compact 1/8 DIN case that requires less than 104 mm (4.1") 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
Power options include isolated 9 to 32 Vdc and 26 to 56 Vdc. A splash-proof lens cover which meets NEMA 4 (IP65) requirements allows the DP3002 to be used in harsh industrial environments.
