Tinsley Precision Instruments Helium Filled Platinum Sheath Resistance Thermometer Model 5187L

This Precision Platinum Resistance Thermometer is constructed in a 5.2 mm platinum sheath 47 mm long with platinum leads passing through a glass seal making the overall length approximately 65 mm.

Construction

The Resistance Temperature Dependent (RTD) element is constructed from a high purity platinum wire and is formed and processed to produce a strain free construction. This is then introduced into a platinum sheath which is helium filled to approximately 1/3 atmosphere at 20°C to reduce the response time to approximately 2 seconds.

Application

The precision thermometer is suitable for use in the temperature range 13.08K to 330K and may be used totally immersed in a liquid, provided the liquid is a good electrical insulator.
