The DP3002-M is a low-cost 4-1/2 digit (±19,999 count) temperature indicator for use with platinum 100 RTD’s with alpha of 0.00385. It is complete with 1 mA sensor excitation, sensor-break detection, and platinum curve linearization. Resolution is 0.1°. Readout can be in °C or °F, as selected by push-on jumpers. The electrical connection can be by 2-, 3-, or 4-wires. High accuracy is provided by positive current feedback and matched, graded components.
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 jumper selection of °C or °F, a linearized recorder output of 1 mV per degree, and 1 mA current excitation. The current source is tied to the reference of the A/D converter for true ratiometric operation and immunity to changes in line voltage.
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.
