If I need to calculate the total heat power through HFS-5, should I multiply the measured heat flux with sensor area (6.5cm2) or total area (9.2cm2)?
Hi Han2021
Thank you for the inquiry. Please forward this question to TEMP@OMEGA.CON.

What is the maximum sampling rate for the HFS-5?
Hi Trevor C
Thank you for the inquiry. Sample rate would be determined by the instrumentation used. Response time of the sensor is 0.6 seconds as noted on the data sheet.

What is the output voltage range for HFS5?
Hi Daniel18
Just under 1 mv at max heat flux. You'll need a meter with micro volt level resolution.

Can the HFS-5 heat flux sensor be used outside in the weather?
Hi Trevor42
Thank you for the inquiry. This sensor is not suitable for outdoor weather conditions.

What is the core material (dark brown) in the HFS-5 sensor and whether it distributes the heat laterally?
Hi Han2021,
Please forward this question over to our temperature group for review; TEMP@OMEGA.COM

we are using the HFS-5 Heat Flux+ T type Thermocouple sensor and the HFS-DAQ. I need to add 8' of length to the wire leads of the sensor to reach our test location. Do you sell these as integral cables? if not, can you suggest extension cables? Thanks
Hi Keithgm,
Thank you for the inquiry. We d not offer integrated cable unfortunately.
For the thermocouple side;
You'll need type T extension wire similar to https://www.omega.com/en-us/temperature-measurement/temperature-wire-and-cable/thermocouple-wires/extt-tx-wire/p/EXTT-T-24-25.
For the heat flux side you can use 2 conductor instrumentation wire (copper).

Hi, I am following up on my question about the output voltage. I need to make sure that my data logger is scaled properly. This sensor has a heat flux range of +/- 150 kW/m^2. Does +/- 150 kW/m^2 correspond to +/- 1 mV respectively? Thank you.
Hi Daniel8,
Please forward your request to TEMP@OMEGA.COM for assistance in scaling a datalogger or other meter.
