All the HTX Heat Flux Sensors can be used bi-directionally. If the direction

of the heat flux is reversed, the sign of the Sensor voltage output changes

(i.e. from positive to negative). Since the sensitivity of the Sensor does not

depend on the direction of the heat flux, the measurement of the reversed

heat flux has the same accuracy.

However, on some voltmeters the measurement of negative voltages may

not be possible or may be less accurate than the measurement of positive

voltages. Further information about the positive and negative sides of the

Sensors can be found in Section 4.

Applicability

Voltmeters are compatible with all the HTX Heat Flux Sensors without a

plug.

7.3 Ohmmeter as a read-out device of temperature

The Heat Flux Sensors of the HTX series have integrated Pt thermistors

which measure average temperature.

The thermistor is useful for experiments where it is necessary to measure

temperature simultaneously with heat flux measurements. And the

measured temperature allows making temperature corrections of Sensor
