N323 Temperature
Thermostats
The N323 is a 3-output
digital electronic controller for heating and cooling applications. It is
available with a NTC thermistor input sensor, Pt100, Pt1000 or J / K /
T type thermocouple.
Sensor offset correction is provided.
Please
Note: In the controller with NTC input, a 3 m-sensor cable is bundled
with the instrument. The cable can be extended up
to 200 m.
The 3 independent outputs can be used as control or
alarm. The features of a particular model (input sensor type, sensor range,
mains supply, etc) are identified by the label
placed on the controller body.
N323R Model: This model of temperature controller controls the end of
defrosting by temperature. It features three output relays:
compressor, defrosting and fan. It operates with
two sensors
(NTC), one for room temperature and other to be attached to
the evaporator for control of defrost end. Employed in cooling
and defrosting.
Example: Frozen chambers and displays.

Details
- INPUT SENSOR: The input sensor type
can be chosen form the options below (specified
when placing the order):
NTC Thermistor, 10 kohm @ 25 °C; range: -50 to
120 °C (-58 to 248 °F); Accuracy: 1,0 °C
(1,1 °F), with original sensor;
Sensor interchangeability: 1 °C (1.35 °F). This error can be compensated
by the offset
parameter in the controller.
Pt100 (a= 385); Range: -50 to 300 °C (-58 to 572 °F); Accuracy: 0,7 °C
(1.3 °F); IEC-751.
Pt1000 (a= 385); Range: -200 to 530 °C (-328 to 986 °F); Accuracy: 0,7
°C (1.3° F);
J, K or T thermocouple (IEC-584):
Type J: Range: 0 to 600 °C (32 to 1112 °F); Accuracy: 3 °C (5.4 °F);
Type K: Range: -50 to 1000 °C (-58 to 1832 °F); Accuracy: 3 °C (5.4 °F);
Type T: Range: -50 to 400 °C (-58 to 752 °F); Accuracy: 3 °C (5.4 °F);
Note: In the controller with NTC input, a 3 m-sensor cable is bundled
with the instrument.
The cable can be extended up to 200 m.
