FIELD: oil and gas extractive industry.
SUBSTANCE: device has infrared radiation sensor, optical system, heat flow modulator and electronic stabilization block for modulator rotation frequency, sensitive element temperature stabilizer and electronic heat-adjustment and heat-stabilization block for sensitive element, block for amplification and conversion of information signal and registering device on the surface. Stabilizer of sensitive temperature element is made in form of thermostat, in which infrared radiation sensor and heat flow modulator are placed, and which is equipped with heating means and inlet port, transparent for infrared radiation. In thermostat, temperature is set and supported at level of upper limit of measured value.
EFFECT: higher precision of detecting of behind-column crossflows.
