1 General Specifications Model RS and RN Resistance Temperature Sensor GS 06B04D01-00E GENERAL Model RS and RN Resistance Temperature Sensors (RTSs) have a platinum resistance element (Pt 100 or 50 ) in a metal sheath which is joined to a terminal. The metal sheath has insulating powder (MgO: magnesium oxide) packed tightly between the sheath and the sensor, so that the sensor cannot move. The tube is flexible, durable and mechanically strong, and the sensor s thermal response is fast. The Model RS has compensation leadwires terminated in crimp-on lugs or metallic connectors. The sensor can be pipe threads mounted or clamped in place. This type of sensor is suitable for laboratory use or for use with simple measuring instruments. The Model RN RTS has a nipple joined to a terminal box. It can be flange mounted, using a fixed flange, or pipe threads mounted. The terminal box of the Model RN-5 RTS contains a spring by which the RTS can be installed tightly to the measuring site. The operating temperature range depends on the resistance element; -200 C to +100 C, 0 to +350 C or 0 to +500 C. These RTSs conform to JIS standards. RTSs conforming to IEC or DIN standards are also available to order. STANDARD SPECIFICATIONS Construction: R.T.S. (mineral insulated type) Mounting Style: RS-l....

Number of Element: Single or double. Sheath Material: Stainless steel (JIS SUS 316) Note: Users must consider the characteristics of selected wetted parts material and the influence of process fluids. The use of inappropriate materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage to plant facilities. It is also possible that the instrument itself can be damaged and that fragments from the instrument can contaminate the user's process fluids. Be very careful with highly corrosive process fluids such as hydrochloric acid, sulfuric acid, hydrogen sulfide, sodium hypochlorite, and high-temperature steam (150 ºC [302 ºF] or above). Contact Yokogawa for detailed information of the wetted parts material.
