Resistance Temperature Detector
Resistance temperature detector (RTDs) i.e. resistance thermometer are invariable used for temperature measuring between – 200°C to 600° C in this temprature range. RTDs are perferred to thermocouples and other sensors because of thier accuracy. Reliability , compact size and faster responce. RTDs find use in almost all industries like plastic and rubber processing, food industries, pharmacueticals, chemicals and petrochemicals plants, power plants, diesel engine and ship, process control and in laboratories for temperature measurment and control.
RTDs are available with simplex and duplex resistance elements and in 2 or 3 wire circuit. A Variety of protecting sheath, mounting connection, construction, design and mounting heads make the RTDs suitable to most of the temprature measurment problems.
RTDs assemblies are normally consist of an inset outer protecting sheath with mounting conection and cast aluminiume terminal Heads. The Inset connection leads, insulated by ceramic multibore insulating tube aurrounded by stainless steel or Brass tube attached to a spring loaded arrangement at the other end so as to protect tghe resistance elementagaisnt vibration and shocks normally encounted in industrial use.
RTDs for Special Applications
RTDs assemblies as per the illustration are normally used for temprature measurement in diesel engines,Locomotive for bearing temprature monitoring etc.Special RTDs assemblies for use in Plastic & Rubber processing machine and for any specific appplication are offered on request.
RTDs assemblies are also offered with custom built design of thermowell with screw in mounting or flanges for high pressure application. Mineral (MgO) insulated compact RTD assemblies for stringent use,i.e. in reactor are also available.
