  • 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 CapTouch 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 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.


    Why you should buy:
  • The ProtEX-FarVu PD6870 is a rugged, explosion-proof, loop-powered meter with 1" display digits ideal for demanding applications in hazardous areas or in the harshest environmental conditions. The product 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. 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.
