The ProtEX+ loop-powered explosion-proof & intrinsically safe flow rate/totalizers can be installed virtually anywhere to provide convenient and informative display of any 4-20 mA signal. They can operate down to -40°C and be installed in areas that get as cold as -55°C, however the display will cease functioning. One of the most convenient features is the dual-line display, typically used to display the flow rate on the 5-character alphanumeric top display and flow total, flow grand total, or tag on the 8-character alphanumeric bottom display. The top display uses 12-segment, and the bottom display uses 14-segment alphanumeric characters for clear indication of tags, units, or alarm messages. Further enhancing the display on these instruments is a 20-segment bargraph.

The ProtEX+ Series is CSA Certified as Explosion-Proof / Dust-Ignition Proof / Flame-Proof and ATEX and IECEx Certified as Intrinsically Safe.

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

All models come equipped with two open collector outputs and a digital input. There are also models available with two solid-state relays and isolated 4-20 mA analog output options. The relays can be programmed for alarm indication, sample, timer, batch control, or stopwatch.

The ProtEX-MAX PD8-765 explosion-proof, large-display, process and temperature meter offers all the functionality of the Trident X2 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). PD8-765's huge 1.2" (30.5 mm) sunlight readable display that is visible from over 30 feet away. This explosion-proof indicator can be field programmed to accept process voltage (0-5 V, 1-5 V, etc.) and current (4-20 mA) inputs, 100 Ohm RTDs, and the four most common thermocouples. The intensity of the display can be adjusted to compensate for various lighting conditions, including direct sunlight. The meter 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. Options for the PD8-765 process and temperature indicator include 2 relays, a 4-20 mA output, and a 24 V transmitter power supply.

The PD663 is a loop-powered field meter that is CSA Certified as Explosion-Proof, Dust-Ignition-Proof, and Flame-Proof, and ATEX & IECEx Certified as Explosion-Proof. It is available in either an aluminum or stainless steel enclosure with ¾" or M20 connections. The PD663 is easy to install and program and it can be seen in a variety of lighting conditions, even in bright sunlight. It will operate down to -40°C and is approved for installation in areas where the temperature gets as cold as -55°C, however the display will cease functioning.

The PD6300 is a member of the ProVu series of 1/8 DIN digital panel meters that is specifically designed to display flow rate and total from a pulse output (NPN, PNP, TTL, switch contact, sine wave, etc.) flowmeter. It displays that signal on a dual-line, 6-digit display that is available with optional Sunbright® sunlight readable LEDs. Flow rate is typically displayed on the upper line and the cumulative total is displayed on the lower line. The total overflow feature allows up to a 9-digit total and grand total to be displayed. Like all ProVu meters, the PD6300 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 PD6300 includes a 24 VDC power supply to drive the flowmeter and can be programmed via the front panel pushbuttons or free MeterView® Pro software.
