Resistance Temperature Detectors (RTDs) ensure precise and repeatable temperature measurement. Watlow has a variety of resistance temperature detectors (RTD) sensors available that are specially designed to ensure precise and repeatable temperature measurement. Sensors are built to meet the most demanding industrial applications while providing a lower total cost of ownership for our customers.
- Strain-free construction provides dependable, accurate readings and allows elements from different lots to be substituted with no recalibration needed
- High signal-to-noise output increases accuracy of data transmission and permits greater distance between sensor and measuring equipment
- Temperature coefficient (alpha) carefully controlled while insulation resistance values exceed DIN-IEC- 51 standards ensures sensor sensitivity
- Stoves, grills, fryers and other food equipment
- Textile production
- Plastics processing
- Petrochemical processing
- Air, gas and liquid temperature measurement
- Exhaust gas temperature measurement
- Semiconductor processing
- Bearing and gear boxes
Standard Industrial Insulated Leads – Style RB
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 temperatures from -50 to 260°C (-58 to 500°F). These RTDs are manufactured in diameters from 0.125 to 0.250 inches.
Plug or Jack Termination – Style RC
Style RC RTDs are manufactured with durable connectors with copper pins for plug or jack termination applications. These provide simple connection to extension leads and have a 200°C (400°F) temperature rating. In addition, the RTD has a crimp, compression adapter that assures superior connector attachment with high accuracy and dependable readings. Style RC RTDs are constructed of 316 stainless steel for a durable, rigid sheath with temperatures from -50 to 260°C (-58 to 500°F).
Connection Head – Style RR
Style RR connection heads provide superior dust and moisture resistance and come in single and double threaded fittings. These weatherproof plastic heads resist weak acids, organic solvents, alkalies, sunlight and dust. Complete assembly is available.
Thermowells – Style RT
Thermowells protect the sensor from the process and allow for change-out on the fly. They are constructed of a variety of high quality materials and are available with spring-loading to ensure positive contact every time.
