The Precision Digital Trident PD765 digital panel meter is one of the most versatile meters on the market and will satisfy a wide variety of process and temperature applications. Housed in a 1/8 DIN enclosure with a NEMA 4X front, the meter 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 display height on the standard Trident meter is 0.56″ (14.2 mm), and on the Trident X2, the display height is an astounding 1.2″ (30.5 mm). The intensity of the display can be adjusted to compensate for various lighting conditions, including direct sunlight. Programming and setup can be performed with the four front panel push buttons, free MeterView software, or using the copy function. Options for the PD765 include two relays, a 4-20 mA output, 24 V transmitter power supply, and Modbus® serial communications.

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
