The ProtEX-MAX PD8-6001 explosion-proof level indicator offers all the functionality of the ProVu PD6001 as a CSA, ATEX, and IECEx certified explosion-proof product. It is available in an aluminum or stainless steel enclosure and will operate over a wide temperature range of -55 to 65°C (-67 to 149°F). It is specifically designed to display level in feet & inches, instead of the usual decimal format. The meter accepts a process current (4-20 mA) or process voltage (0-5V, 1-5V, etc.) signal and displays that signal on a dual-line display with convenient feet and inches designations on the upper line. The upper display can even read fractions of an inch in 8ths or 16ths. The lower line can be used to indicate a tag or to display the input in another scale, such as volume in gallons or liters. The PD8-6001 includes a 24 VDC power supply to drive the transmitter and can be equipped with four internal relays and a 4-20 mA output. It can be programmed and operated without opening the housing by using the built-in SafeTouch through-glass buttons or the RS-485 serial communication port with free Modbus protocol.
