Watlow Style RB RTD Sensor with Lead Wires
Standard Industrial Insulated Leads
Watlow provides a complete line of RTDs for a wide variety of industrial and process applications. These sensors have been designed to ensure precise and repeatable measurements as well as meet the environmental requirements for the application. RTD sensors may be configured to meet your specific application need with options including, but not limited to the following: element type, lead wire configuration, termination style, sheath materials, lengths and diameters, process connection heads, transmitters, thermowells, spring loading, flanges and surface mount packages. Please call us to configure an RTD you need that is not available on this website.

Watlow's RTD platinum resistance element temperature sensors are specially designed to ensure precise and repeatable temperature versus resistance characteristics. The sensors are made with controlled purity platinum, have high purity ceramic components and are constructed in a unique strain-free maner.

Style RB RTDs have standard, insulated leads with an internal heat transfer plate for a quick time response and high accuracy. These RTDs are also epoxy sealed to resist moisture and pull out. There is a standard 260°C (500°F) potting. Style RB RTDs are constructed of 316 stainless steel for a durable, rigid sheath with temperature from -50 to 260°C (-58 to 500°F). They are manufactured in diameters from 0.125 to 0.250 inches.
