Model DT-8300EX
INSTALLATION
AMETEK Model DT-8300EX is designed to be mounted in the field, either on a 2” pipe or wall/panel. AMETEK carries
both types of 316 SST mounting brackets.
All inter-connections to the instrument should be made with strong multi-strand wire of the order of 1.5 sq. mm.
The ends of the wires should be properly ferruled and suitable lugs must be used for effective termination. The
Cables carrying the Input Temperature sensor signal should be compensating type cable for the specific Sensor only.
Care must be taken to properly isolate this Cable from any Power Line cables in the vicinity (even separate router
channels) to prevent any induced voltages or electromagnetic “noise” interferences in the input signal readings from
disturbances in the Main Power Line. It is recommended that the polarities of the input signal be double-checked for
correctness before energizing the instrument. The maximum recommended distance of the Temperature Sensor from
the indicating instrument is 15 meters.
OPERATION
Remove the electronics from the outer housing and loosen the two screws on the face plate to access the switches
on the back of the electronics.
Upon switching on the Power switch, the digital display will immediately indicate the actual process temperature value
in the selected units. A switch on the rear of the instrument allows for switching of the units from ° F to ° C.
The temperature display is factory calibrated for the individual Thermocouples (J or K type) and RTD (Pt 100); and
no settings are required to be done by the user. The display will update at intervals of ten seconds. If the Switch for
selecting the temperature units is used, the display will update with the selected units after the 10 seconds period.
The Batteries to be used for the instrument are the commonly available type AA (1.5V), in series configuration.
It is strongly recommended that only competent and authorized personnel should attempt any settings, alterations or
rectifications in the instrument.
