Versatile Bio Sensor Guide: Temperature
Understanding the temperature sensor on the Versatile Bio
What it measures:
The temperature sensor (TEMP) measures temperature changes at the site of the probe.
Physiology, sports, kinesiology, biomechanics, etc.
How to use:
The probe should be placed where temperature should be measured. It can be attached to the body with appropriate medical tape or adhesive. As with any temperature sensor, direct sunlight can alter the recorded temperature drastically.
How to clean:
The temperature probe can be cleaned with a disinfectant wipe or with a small bit of mild detergent and water. Avoid getting the connector wet. Let the device dry completely before using.
Autoclave is not recommended.
Connector on Versatile Bio:
A data visualization filter is not necessary for the temperature sensor. For live data viewing, you will have to reduce the data scale for the analog channel until the signal is visible.
Sensor Range: -50 degrees C to 105 degrees C in air, -55 degrees C to 70 degrees C in fluid
Dissipation Factor (in air): 3 mW / degree C
Thermal time constant (in air): 75 seconds
Data is reported as analog voltage in µV, listed as (analog V) in the formula below. To convert to temperature in C, use the following:
In MS excel, the conversion formula would look like this (analog V values in µV as recorded by the temperature probe in column A, enter formula between [ ] marks into B, C and D):
A1 = Recorded (analog V) value
B1 = [=10000/((3.3/A1)-1)]
C1 = [=1/(0.003354+(LN(B1/10000)/3435))]
D1 = [=C1-273.15]
C1 = Temperature in degrees K
D1 = Temperature in degrees C
