The ProtEX-MAX PD8-6000 explosion-proof process meter offers all the functionality of the ProVu PD6000 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 accepts a process current (4-20 mA) or process voltage (0-5V, 1-5V, etc.) signal and displays it on a dual-line, 6-digit Sunbright sunlight readable display. The meter includes a 24 VDC power supply to drive the transmitter and can be equipped with four internal relays and a 4-20 mA output. The PD8-6000 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.

The PD685 is an easy to use, loop-powered indicator, certified by CSA, ATEX and IECEx as intrinsically safe. The PD685 carries international certifications under both the Class/Division System and Zone System, and is thereby suitable for use in gas and dust hazardous areas worldwide. For Division 2 applications where intrinsically safe interfaces are not needed, the PD685 is able to be installed without barriers! To achieve this ability, the PD685 underwent a special 'nonarcing assessment' under the UL 121201 and CSA C22.2 No. 213 standards, and was determined to be a device incapable of causing an ignition on its own. The PD685 is wellsuited for both indoor and outdoor applications and carries a variety of environmental ratings, including NEMA 4, Type 4X and IP67.

The PD685 can be seen from considerable distance in bright sunlight or dimly lit areas when the standard backlight feature is activated. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area. The meter gets all of the power it needs from the 4-20 mA loop and its 1 V (4 V with backlight) drop results in a minimal burden on the loop. The meter features a wide -40 to 75°C operating temperature range and is available with a ½" conduit hole in a location of your choice for easy installation. Calibration is a quick two-step process involving the adjustment of only two sets of coarse and fine, non-interacting potentiometers.

The PD6060 is a member of the ProVu series of 1/8 DIN digital panel meters that accepts two inputs of either a process current (4-20 mA) or process voltage (0-5V, 1-5V, etc.) signal. It displays these signals on a dual line, 6-digit display that is available with an optional Sunbright® sunlight readable LEDs. The meter can be customized such that these two inputs are displayed in a variety of ways, including both at the same time with tags or the result of math functions performed on one or both of the inputs. Like all ProVu meters, the PD6060 includes UL / C-UL listing and CE marking, a NEMA 4X front, and AC or DC power options. The PD6060 can also be equipped with up to four internal relays, a 4-20 mA analog output, and Modbus® serial communications. The PD6060 includes a 24 V DC power supply to drive the transmitters. ProVu meters can be programmed via the front panel pushbuttons or free MeterView® Pro software.

Go with the Helios PD2-7000 when you want to display temperature on a large display meter you can see from a distance. The PD2-7000 can accept a variety of thermocouples and RTDs and displays temperature on a six digit display. The PD2-7000's NEMA 4X enclosure, super bright LEDs, and wide operating temperature range make it perfect for outdoor applications.
