Thermistor cartridge

Does anyone know the maximum temperature the Prusa thermistor cartridge can read?

 

Thank you

Well, they use an e3D cartridge so: 285C

Thank you! E3D rates the maximum temperature as 285°C.

Thank you

The 104GT-2 thermistor, for example, can handle temperatures in the range of -50 to +300 degrees. You don't need more than 280 degrees C. with the MK3 for printing the most common materials.

Is that was Prusa sells?  I thought they sold an e3D.

I cannot confirm the manufacturer of the E3D thermistor now. I have looked in the firmware. There in the thermistor table this type is used. The thermistors will not differ greatly in the values, only the quality of processing (housing and wiring).

THERMISTORS SETTINGS

 *------------------------------------*/

 

//

//--NORMAL IS 4.7kohm PULLUP!-- 1kohm pullup can be used on hotend sensor, using correct resistor and table

//

//// Temperature sensor settings:

// -2 is thermocouple with MAX6675 (only for sensor 0)

// -1 is thermocouple with AD595

// 0 is not used

// 1 is 100k thermistor - best choice for EPCOS 100k (4.7k pullup)

// 2 is 200k thermistor - ATC Semitec 204GT-2 (4.7k pullup)

// 3 is Mendel-parts thermistor (4.7k pullup)

// 4 is 10k thermistor !! do not use it for a hotend. It gives bad resolution at high temp. !!

// 5 is 100K thermistor - ATC Semitec 104GT-2 (Used in ParCan & J-Head) (4.7k pullup)

// 6 is 100k EPCOS - Not as accurate as table 1 (created using a fluke thermocouple) (4.7k pullup)

// 7 is 100k Honeywell thermistor 135-104LAG-J01 (4.7k pullup)

// 71 is 100k Honeywell thermistor 135-104LAF-J01 (4.7k pullup)

// 8 is 100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup)

// 9 is 100k GE Sensing AL03006-58.2K-97-G1 (4.7k pullup)

// 10 is 100k RS thermistor 198-961 (4.7k pullup)

// 11 is 100k beta 3950 1% thermistor (4.7k pullup)

// 12 is 100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup) (calibrated for Makibox hot bed)

// 13 is 100k Hisens 3950  1% up to 300°C for hotend "Simple ONE " & "Hotend "All In ONE"

// 20 is the PT100 circuit found in the Ultimainboard V2.x

// 60 is 100k Maker's Tool Works Kapton Bed Thermistor beta=3950

Very interesting.  I have seen that value table before but did not put 1 and 2 together.
