Canadian Standards Association European Conformity
The ProtEX-MAX™ PD8-7000 offers all the functionality of the ProVu PD7000 as a CSA Certified explosion-proof product. It is available in an aluminum or stainless steel enclosure. It 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 Sunbright sunlight readable display. The meter includes automatic cold junction compensation for thermocouples and the ability to average up to ten (10) RTD sensors. The PD8-7000 can be equipped with four internal relays and a 4-20 mA analog output. It can be programmed and operated without opening the housing by using the built-in SafeTouch® through-glass buttons or the RS485 serial communication port with free Modbus® protocol.
