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 the wiring diagrams below. All
connections should be made using either butt-splices or soldering. The use of wire nuts is not recommended.
•
Thermistors are a 2 wire hook up and are not polarity sensitive. See Figure 6.
•
RTD’s are a 3 wire hook up. 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.
