TE Technology TC-720 - Manual (Page 45)

TEMPERATURE SENSOR BOX
This allows for selecting the type of temperature sensor being used with the controller for the control sensor (SENSOR 1
TYPE) and the secondary sensor (SENSOR 2 TYPE).
Most of the sensor options correspond to various negative-temperature-coefficient thermistors that TE Technology offers.
The temperature-resistance tables for the various sensors are provided in the appendix for reference. Additional
information on the thermistors is available online at www.tetech.com .
The 15k-1 TS-67 is the default selection. Using this sensor type provides a control range of -20 °C to +100 °C. The MP-3193 is
the standard thermistor provided with the TC-720 and has a temperature-resistance curve corresponding to the 15k-1
TS-67 type. The MP-2444, MP-2996, and MP-2542 optional thermistors are also of this type.
The 5k-1 TS-141 provides a control range of -40 °C to +70 °C. The MP-3176 is of this type.
The 10k-1 TS-91 provides a control range from -20 °C to +85 °C. The 10k-2 TP-53 provides a control range of -15 °C to
+80 °C. While TE Technology does not offer standard 10 kΩ thermistors at the present time, these two sensors correspond
to common 10 kΩ thermistors that are offered by other vendors.
The 50k-1 TS-104 provides a control range from 0 °C to +150 °C. The MP-3022 is of this type.
The 230k-1 TS-165 provides a control range from +25 °C to +199 °C. TE Technology does not offer standard thermistors of
this type at the present time.
Depending on the sensor being used, the HIGH EXTERNAL SET RANGE and LOW EXTERNAL SET RANGE may need further
adjustment.
Be sure that you have selected the correct sensor type. A dangerous condition could exist because the actual
temperature could be higher or lower than the temperature being interpreted by the controller.
