PD7000 ProVu Temperature Digital Panel Meter
The PD7000 is a member of the ProVu series of 1/8 DIN digital panel meters that accepts a direct temperature input from a wide range of temperature measurement devices (type J, K, T, E, R, S, B, N, and C thermocouples and 100 or 1000 Ω platinum, 10 Ω copper, 120 Ω nickel RTDs). It displays the measured temperature in either degrees Fahrenheit or degrees Celsius on a dual-line, 6-digit display that is available with optional Sunbright® sunlight readable LEDs. The PD7000 temperature indicator includes automatic cold junction compensation for thermocouples and the ability to average up to ten (10) RTD sensors. Like all ProVu meters, the PD7000 temperature meter includes UL / C-UL listing and CE marking, a NEMA 4X front, and AC or DC power options. ProVu meters can be equipped with up to four internal relays, a 4-20 mA output and Modbus® RTU serial communications. The PD7000 can be programmed via the front panel pushbuttons or free MeterView® Pro software.
