Temperature Sensor Calibration File Generator

Generate a Syvecs-compatible .txt calibration file from your sensor's resistance/temperature data sheet.

How it works: Enter your sensor name, select your Syvecs product, and paste the temperature/resistance data from the manufacturer's data sheet. The tool converts resistance values to voltage using the correct pull-up resistor value for your selected product and a fixed 5V reference, then generates the correct SENSOR() file format ready to load into SCal.

Installing the generated file: Once downloaded, copy the .txt file to: C:\Program Files (x86)\Syvecs\SensorDB\
Then start SCal — your sensor will be available under the Linearisation function in the Sensor DB.

Enter data from your sensor's data sheet below. A minimum of 16 data points is required; all 20 rows are not necessary.

How to load this file into SCal

  1. Copy the downloaded .txt file to:
    C:\Program Files (x86)\Syvecs\SensorDB\
  2. Start SCal (if it was already open, close and reopen it). Your sensor will now be available in the Sensor DB under the Linearisation function.
  3. Navigate to the sensor in Defined Sensors and Trips Setups or User Definable Sensors.
  4. Locate the specific sensor you wish to configure.
  5. Select Input Configuration and adjust the configuration of the input.
    Note: Some inputs have a pull-up resistor built into the hardware and do not require software configuration. On the S7, pins AN13–AN16 (C22–C25) have a fixed 3.3kΩ hardware pull-up and are always active — no software toggle is needed. Inputs AN01–AN08 and Slave Analog inputs AN S1–S6 have software-selectable pull-ups and must be manually enabled by setting Input Configuration to Thermistor (TH) or toggling the Input Pull Up option. Voltage inputs AN09–AN12 have no pull-up capability.
  6. Click Program (Device → Program) to write the calibration to the ECU.
