PRECISION DIGITAL Trident PD765 - Data Acquisition; Data Logging up to 100 Meters; Process and Temperature Inputs; Current & Voltage Inputs

PROCESS & TEMPERATURE INPUTS
The Trident is factory calibrated to accept 4-20 mA, ±10 VDC,
type J, K, T, or E thermocouples and 100 Ω platinum RTDs.
Process inputs can be scaled with or without applying an input
for virtually any engineering units. Temperature inputs can be
programmed to display in degrees Fahrenheit or Celsius and the
type K thermocouple can display up to 2300 °F.
Current & Voltage Inputs
Setting up the meter to accept a current or voltage input could not be
easier. All setup is performed with the front panel buttons and there
are no switches or jumpers to deal with.
Current Overload Protection
To protect the instrument from unexpected current overload, the
current input circuit contains a resettable fuse. The fuse limits
the current to a safe level when it detects a fault condition, and
automatically resets itself when the fault condition is removed.
Thermocouple & RTD inputs
Setting up the Trident to accept a thermocouple or RTD input
is simply a matter of setting a switch at the rear of the case and
selecting the input type from the menu.
The meter accepts J, K, T, or E type thermocouples as well as
two,three,orfour-wire100ΩplatinumRTDs.

DATA ACQUISITION
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.
