The ProtEX-MAX PD8-765 explosion-proof, large-display, process and temperature meter offers all the functionality of the Trident X2 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. 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 RS485 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.

MeterView® for Trident
MeterView software allows remote programming and data acquisition of the Trident series. The remote programming allows for all available meter settings to be programmed from a personal computer through an easy user-friendly interface. The data acquisition allows the user to gather readings from up to 100 meters at user-selected intervals and generate charts using common tools like Microsoft® Excel.
Digital Panel Meters make a great front end to a PC-based data acquisition system. They are easy to set up, can be used for a wide range of inputs, will power the transmitter, and best of all provide a local display of the process. Precision Digital has the perfect package with its Trident Digital Panel Meters, a wide selection of serial adapters and converters and free MeterView software. Data is displayed on the PC and written to a file that could then be imported into a spreadsheet or other application.
Data Logging up to 100 Trident Meters
Sample File Generated by MeterView®
Great for tank level monitoring!
