WIRING
•
Use 18 - 24 AWG shielded wiring for all connections. Do not locate the device wires in the same conduit with wiring used to supply inductive
loads such as motors. Make all connections in accordance with national and local codes.
•
Pull at least six inches of wire into the enclosure, then complete the wiring connection according to wiring diagrams below.
•
Thermistors are a 2 wire hook up and are not polarity sensitive. See Figure 6.
•
RTD’s are a 3 wire hook up see Figure 7.

TYPICAL WIRE RESISTANCE VALUES
When using low resistance sensors, long wire runs can add significant error
to the readings. Use the following chart to determine errors due to wire
resistance or consider using a 1000 ohm sensor or a transmitter for better
accuracy. Locate the type of wire being used. Multiply the total length of the
wire (distance from the controller to the sensor and back) by the number
found in the chart below for total resistance.

NOTE:
The sensor accuracies listed in the specifications section apply to the
sensing element only prior to product assembly and may not be reflected in
the complete assembly.
Due to the measurement uncertainty, it is possible, that the true resistance
value of the single delivered sensor at 0°C can be out of the defined tolerance
class. Profiling each assembly to take into consideration lead wire and the
attachment method should be completed.
