CFTC-1L

CFTC-1L

This is a module that can measure temperature using thermocoupler K, J, T, N, E, S, B, and R type sensors.

Electrical specifications

Sensor input points: 1 channel
Conversion unit: 0.0625°C
Error rate: ±1.5°C
Isolation: No isolation

Measurement range by sensor type

Type K: -200°C ~ 1350°C
Type J: -150°C to +1200°C
Type T: -200°C to +400°C
Type N: -150°C to +1300°C
Type E: -200°C to +1000°C
Type S: 250°C to +1664°C
Type B: 1000°C to +1800°C
Type R: 250°C to +1664°C

* Although the CFTC-1L's hardware and design is rated for the broad ranges listed above, and can be used with probes rated for those ranges, the CFTC-1L has only been validated for temperatures in the range of -50℃ ~ 500℃.

Wiring method

Setting the module's address

Up to 8 CFTC-1L modules can be used in one system, each with a different address in the range of 0x00~0x07.
The address setting method is different from other I/O modules: Only one of the DIP switches should be turned ON at any time.

How to use the API

1. <html>

#include "CFMEGA.h"

</html> library registration

2. CFNET object creation: e.g. CFNET object name ⇒ CFNET cfnet;

3. Call the function(s):

Object Name.tcSetInit(); ⇒ cfnet.tcSetInit(0,0);
Object Name.tcTempRead(); ⇒ cfnet.tcTempRead(0);

-u8 tcSetInit(u8 addr, u8 sensor)

This function sets the sensor type to be used for the address module specified as the initialization setting.

address: module dip switch value (0~7)
sensor: Sensor type (Type K = 0, J = 1, T = 2, N = 3, S = 4, E = 5, B = 6, R = 7)

- float tcTempRead(u8 addr)

Reads the measured temperature value as a floating point type to the second decimal place.

address: The address of the module as configured by its DIP switch (0~7)

A value of -1111 is returned if a thermocouple is not connected, or an otherwise invalid reading is detected (e.g. the value read is out of range for the thermocouple type).

#include "CFMEGA.h"
CFNET cfnet;
 
void setup() {
 Serial.begin(9600);
 cfnet.tcSetInit(0,0);
 cfnet.tcSetInit(1,0);
}
 
void loop() {
 float k_temp_0 = cfnet.tcTempRead(0);
 float k_temp_1 = cfnet.tcTempRead(1);
 
 Serial.print("Thermocouple 0 : "); Serial.print(k_temp_0); Serial.print("°C"); Serial.println();
 Serial.print("Thermocouple 1 : "); Serial.print(k_temp_1); Serial.print("°C"); Serial.println();
 Serial.println();Serial.println();
 delay(200);
}

Sensor type

You need to purchase a wire-type sensor to connect this product. If you already have the connector-type, open the connector and convert it to wire-type.
