H&B Sensors RFA101 & RFA401 – RTD Sensor with Solid Drilled Flanged Thermowell

H&B Sensors RFA101 and RFA401 are temperature assemblies combining a spring-loaded RTD sensor with solid drilled flanged and stepped flanged thermowells. This heavy-duty construction is designed for use within applications involving high pressures and flow rates.

The RTD temperature sensor is available as a 2, 3 or 4 wire Pt100 or Pt1000 in either simplex, duplex or triplex configuration. The accuracy class can be selected from 1/10 DIN, 1/5 DIN, 1/3 DIN, class A or class B.

This assembly is available with an aluminium, stainless steel or plastic connection head which has an M20 x 1.5 cable entry. The sensor can be terminated with a ceramic terminal block, 4 to 20 mA transmitter or supplied with tails. There is also an option to specify a loop-powered or battery-powered indicator.

The H&B Sensors RFA101 thermowell is available with either a parallel or tapered stem profile and has wide variety of process thread connections available.

The solid drilled thermowells are available in a wide selection of materials including 316 stainless steel, Alloy C276 (Hastelloy®), Alloy 400 (Monel®) and Alloy 600 (Inconel®).

Both RFA101 and RFA401 assemblies are available with ATEX Exia, IECEx Exia, UKEX Exia (intrinsically safe), ATEX Exd, IECEx Exd or UKEX Exd (flameproof) hazardous area approval for use within Zones 0, 1, 2, 20, 21 and 22.

Fluidic are the Scottish and Northern England partner for H&B Sensors.  We also have an exclusive agreement for supply to the UK nuclear industry  Our instrumentation engineers are product trained and are able to help with instrument selection within the full H&B Sensors supply scope.  Most products can be custom made for the application.  Please call either office for more information (Glasgow 0141 641 5920,  Warrington 01925 572401).
