New RealProbeTemp Temperature Assembly

Featured Product from Innovative Sensor Technology IST USA Division

New RealProbeTemp Thin-Film RTD Temperature Assembly 

The RealProbeTemp is a pre-assembled stainless steel probe containing a 100 Ω platinum thin film RTD temperature element with an operating range from -50°C to +200°C.  The probe sheath is tip sensitive, providing superb response times and the ability to measure in liquids at a minimum depth.  The assembly can also be applied as a stand alone probe or a sub assembly. 

Reduced Response Times and Immersion Depth

Utilizing a special, thermally conductive metallization construction encased in thin wall tubing, IST’s RealProbeTemp provides an unequaled probe assembly with a fast response time and reduced immersion depth.  Measured in water at 0.4 m/s, it is able to achieve 90% of the temperature change in less than 1.5 seconds, and 63% in less than 0.5 seconds.  This is a significant improvement when compared with conventional probes, even those with much smaller outer diameters.

 For accurate measurements, standard probe assemblies require a depth of 25 to 30mm, whereas the RealProbeTemp requires only 10mm or slightly less.  It is ideal for applications with reduced space and large temperature gradients between the measurement medium and the surrounding atmosphere. 

 Stand Alone Probe or Sub Assembly

The RealProbeTempcan act as a stand alone probe assembly or as a sub assembly insert to minimize the fabrication processes and materials necessary for larger or more complex probe assemblies.  The pre-assembled and inspected unit thus results in reduced manufacturing costs and construction efforts. The tip sensitive construction allows for this RTD temperature probe to be used as a bearing temperature sensor or surface contact temperature sensor.

The RealProbeTemp Technology is applied in thermal flow sensors providing turnkey features for flow meters and flow switches. Custom designs are possible to be incorporated in order to interface with existing flow sensor devices and systems.
