Key parameters
Measuring range
−50 to 260 °C (−58 to 500 °F) for Style RB rigid sheath construction
Accuracy
DIN/IEC 60751 Class A or Class B element options (typical Watlow RTD offering on RICRTD sheet)
Output
Passive RTD resistance (no transmitter in base Style RB)
Process connection
Plain sheath; use with fittings/thermowells as required by application
Approvals
Built to industrial RTD practice per Watlow RICRTD specification sheet
Sensor type
Style RB standard industrial RTD with insulated leads, internal heat-transfer plate, epoxy potting
Fits standard industrial RTD sensing where you need a Watlow Style RB rigid 316 SS sheath with insulated leads, epoxy potting, and −50 to 260 °C operating class.
Key advantages
- Style — RB rigid sheath RTD with insulated leads and epoxy potting
- Range — −50 to 260 °C (−58 to 500 °F)
- Elements — 100 Ω or 1000 Ω Pt; 2-, 3-, or 4-wire
- Sheath — 316 SS; typical diameters 0.125 to 0.250 in
- Leads — Epoxy-sealed against moisture pull-out; configurable lengths
Typical applications
- General industrial temperature with fittings/wells.
- OEM equipment RTD points.
- Medium-temperature process air/liquid.
Selection guide
- Ω / wires — 100 vs 1000 Ω; 2/3/4-wire
- OD / length — Sheath geometry
- Class A/B — Element tolerance
- Fittings — Compression/thermowell
Common mistakes
- Using RB above 260 °C — choose higher-temp MI styles.
- 2-wire on long runs with lead error.
- Plain sheath without required fitting.
When to RFQ / what to tell us
- Ω/wires, OD, length, class.
- Quantity and ship-to.
