RH style probes provide a rugged housing for a connection block or temperature transmitter that allows for installation of instrument wire through conduit to the instrument room.  Connection heads provide protection from the elements and easy access to sensor or transmitter.  Heads are available in aluminum, cast iron or polypropylene.  Explosion proof heads are available in aluminum or stainless steel and are available with FM/CSA approvals.  RH probes provide ½” stainless steel process threads in either fixed or spring loaded for thermowells.  Standard Aluminum, Cast Iron or Explosion Proof heads are able to accommodate standard DIN temperature transmitters.  Contact the factory and specify range and °C or °F.
