Page 9: Heat Flux Interface
Heat Flux Interface The SP-016 provides heat flux measurements in W/m . Heat Flux sensors, such as the OMEGA HFS-05, consist of a thermopile device and a temperature compensation (TempCo) measuring device, typically a T type thermocouple. For OMEGA HFS products, the heat flux is calculated as: q”... -
Page 10: Thermocouple Configuration
Thermocouple Configuration The SP-016 uses a thermocouple input for temperature compensation and provides interfaces to type J, K, T, E, N, R, S, B, and C thermocouples with the capability of enabling or disabling the open detect feature. To use these features, follow... -
Page 11: Cold Junction Calibration
Cold Junction Calibration The SP-016 has automatic Cold Junction Compensation and is factory calibrated so that in most cases it needs no adjustment. However, for increased accuracy, Cold Junction Calibration can be performed as described below. Step 1: Ensure your thermocouple has been configured in the previous section and click Calibration beneath the input interface. -
Page 12: Configurable Digital I/O
Configurable Digital I/O The Layer N SP-016 features 2 configurable digital I/O pins. These can be used for a myriad of applications including driving relays, physical alarms, or sensing dry contacts like door switches. Name Function Pin 1 DIO 0... -
Page 13: On/Off Functions
4.6.2.1 ON/OFF Functions I/O signals can be changed between Active High, Active Low, and inactive. Option Value Description When the output is inactive, it is in a high impedance state. Active HIGH When the output is active, it is in a high impedance state. Set output inactive Value Set output active... -
Page 14: On/Off Control
4.6.4 ON/OFF Control To configure ON/OFF Control on a device, navigate to the Output Configuration Tab in SYNC and click on the icon located to the right of the available outputs. Clicking the icon will open Define ON/OFF Control dialog box as seen below. -
Page 15: Appendix: Sp-016 Registers
The following Appendix provides the registers and list index for the Layer N SP-016 Heat Flux Smart Probe. This information is intended to aid users who will be making configurations and adjustments to their Layer N SP-016 Heat Flux Smart Probe through the Command Line Interface or other custom interfaces. -
Page 16: Data Type
The 4-bit Data Type field determines the type of data of the specific sensor. 5.1.2.2 Factory Calibrate Factory calibration is used on the SP-016 process inputs. Clearing this bit will disable the factory calibration values. 5.1.2.3 Sensor Writeable The writable bit is cleared, indicating that the sensor values may not be overwritten. -
Page 17: Heat Flux Sensor Parameters
5.1.6 Heat Flux User Calibration Parameters The SP-016 provides a single User Calibration register that may be set while the device is in the User Calibrate mode and is ‘added’ to the calculated value during normal operation, providing a fixed offset to the calculated Heat Flux value. -
Page 18: Sensor Trigger Function
5.1.7.1 Sensor Trigger Function The Sensor Trigger function is used to reset the IPSO min/max values as well as controlling the Calibration process. Sensor Trigger Function Reset Min/Max Calibration Calibration Calibration Capture Capture Calibration Reset Status Mode High Start Setting the Reset Min/Max bit to 1 will reset the Min/Max values recorded by the IPSO process. The Calibration mode is entered by writing a 1 to the Calibration Mode bit. -
Page 19: Thermocouple Input Data Type/Format
The 4-bit Data Type field determines the type of data of the specific sensor. 5.2.2.2 Factory Calibrate Factory calibration is used on the SP-016 process inputs. Clearing this bit will disable the factory calibration values. 5.2.2.3 Sensor Writeable The writable bit is cleared, indicating that the sensor values may not be overwritten. -

Page 23: Lock
5.3.3.1 Lock If set, the user-specified units of measure string (4-character maximum) will be used in place of the default DIN. 5.3.3.2 Apply Scaling If set, the user-defined Offset and Gain values will be used to adjust the sensor reading. For more information on Gain and Offset, refer to the Smart Sensor Manual. -
Page 24: Sensor Trigger Function
5.3.5.1 Sensor Trigger Function The Sensor Trigger function is used to reset the IPSO min/max values as well as to control the Calibration process. Sensor Trigger Function Reset Min/Max Setting the Reset Min/Max bit to 1 will reset the Min/Max values recorded by the IPSO process. No User Calibration process is supported on the DIO inputs and all bits should be written as 0. -
Page 25: Outputs
5.4.4 Output Type The SP-016 probe supports NULL (0), ON/OFF (1) or PWM (2) outputs. When set to NULL the output signal will be left in a high impedance state. When set to ON/OFF the Rate information has no effect. -
