Platinum Resistance Tool

The Platinum Resistance Thermometer is used to give a high precision reading of wellbore temperature. It outputs temperature data as a digital word allowing for very high resolution. Because of the small size of the tip it also has a very rapid response time which minimizes the effects of differing line speeds. It can be run alone, or as part of a string of Production Logging tools.

 

OPERATING PRINCIPLE

The change of resistance of a length of platinum wire with changing well temperature is used to drive a voltage controller oscillator. The frequency output from the VCO is digitized and encoded on the line. The high thermal conductivity copper tip is isolated with a low thermal conductivity body which allows for high resolution measurement even with high differential temperatures between the well fluid and the tool body.
