The PD6938 ProtEX+ pulse input flow rate/totalizers can be installed in a variety of areas (hazardous, dirty, wet, corrosive, hot, or cold) to provide convenient and informative display of flow rate and total from any pulse output flowmeter. These instruments will accept a variety of pulse inputs, including slow pulse rates. They can be powered from a battery, 9-30 VDC, or the 4-20 mA output loop, have on-board datalogging capabilities, come with approvals for intrinsic safety, and can be ordered with optional 4-20 mA output and two relays.

The PD6938 can operate down to -40°C and is certified by the agencies to be installed in areas that get as cold as -55°C.

The PD6938 ProtEX+ is available in aluminum and stainless steel enclosures that are designed for easy use and installation. The process connection is available in M20, 3/4" NPT and 1" NPT and there are two other conduit holes for field wiring.

Free, PC-based, MeterView XL software that connects to the meter via a micro-USB cable is available for programming and setup of the instruments. Four CapTouch through-window buttons are available to operate the instrument without removing the cover.

All models come equipped with two open collector outputs and a digital input. There are also models available with Modbus RTU RS-485 communications, two solid-state relays, and isolated 4-20 mA analog output options.

The 1/8 DIN cutout filler is an accessory to the enclosure product line. It consists of a generic bezel with a black faceplate, as well as mounting brackets, gasket, etc.

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.
