ABB TSP131 temperature sensor

ABB TSP131 temperature sensor

If you’re in the market for a reliable, no-fuss temperature sensor that can handle mid-range industrial demands without breaking the bank, the ABB TSP131 temperature sensor is exactly what you need. Part of ABB’s trusted SensyTemp TSP100 series, this sensor is built for light-to-mid-duty applications, making it perfect for independent stations, small factories, and large facility auxiliary systems alike—think chemical processing lines, power plant auxiliaries, water treatment tanks, and general manufacturing machinery. The ABB TSP131 temperature sensor keeps things simple with a modular design (compliant with DIN 43772 standards), but don’t let its straightforward setup fool you—it’s packed with technical features that deliver consistent, accurate readings, even in moderately harsh environments.

Let’s start with the basics: the ABB TSP131 temperature sensor supports both RTD and thermocouple measuring elements, so you can pick what works best for your setup. For RTDs, it’s compatible with thin-film and wire-wound Pt100, Pt1000, and Cu100 options—thin-film handles up to 400°C (752°F), while wire-wound steps it up to 800°C (1472°F), all meeting IEC 60751 standards. Thermocouple-wise, it covers K, J, N, E, S, and B types; S-type can go all the way to 1600°C (2912°F) for high-heat jobs, and all follow IEC 60584 Class I accuracy (±1.5°C or ±0.004t, whichever is bigger). The best part? The measuring inset is replaceable (per DIN 43735), so you don’t have to yank the entire sensor out of the process if something needs swapping—saves you tons of downtime.

One of the ABB TSP131 temperature sensor’s standout features is its one-piece thermowell, made from bar stock material for extra durability and better heat transfer (no flimsy parts here!). Standard material is 316L (1.4404) stainless steel, which works for most applications, but you can upgrade to 316Ti (1.4571), Inconel 600, or Hastelloy C276 if you’re dealing with corrosive media or higher temps. Each material has its limits: 316L tops out at 800°C, Hastelloy C276 hits 1100°C, and Monel 400 caps at 600°C. Process pressure? It handles 40 to 630 bar (580 to 9135 psi), depending on the material and thread size—plenty for most mid-range industrial jobs.

Performance-wise, the ABB TSP131 temperature sensor doesn’t disappoint. It has an adjustable T90 response time (600 ms to 2500 ms)—so you can tweak it to catch fast temperature changes or steady readings, whatever your process needs. Long-term stability is ±0.1% of full scale per year, which means you won’t be calibrating it every few months—huge time-saver for busy teams. Electrical isolation is 2.5 kV AC for 60 seconds, so even in noisy industrial setups (think motors or heavy machinery), it won’t glitch or give bad readings—compliant with IEC EN 61326-1 standards, if you care about that technical stuff.

Durability is key, and the ABB TSP131 temperature sensor is built to last. Connection heads come in epoxy-coated aluminum (standard) or 316L stainless steel (optional)—aluminum is great for most setups, stainless steel for harsher, more corrosive areas. Head options include AGL (screw-on cover), AGD (with LCD), and AGS (stainless steel), all IP67 rated (NEMA 4X)—so dust and water splashes won’t ruin it, even for outdoor installations. Ambient operating temp ranges from -40°C to +85°C, storage from -50°C to +90°C, and it handles 20-95% non-condensing humidity—no sweat in extreme weather.

Integration is a breeze too. The ABB TSP131 temperature sensor offers flexible outputs: direct sensor signal (if you want to pair it with a separate transmitter) or 4-20 mA DC with HART 7 if you opt for the integrated transmitter. It works with 10.5-45 V DC power, loads up to 600Ω, and connects via 2×M20×1.5 or ½” NPT threads—unrestricted mounting, so you can install it wherever it fits. Safety-wise, it’s SIL 2 certified (IEC 61508) for safety-critical loops, with ATEX, IECEx, and FM/CSA approvals for Zone 1/2 hazardous areas—perfect if you’re working with flammable materials.

Configuring it is super easy, even if you’re not a tech expert. Use FDT/DTM tools, a HART handheld terminal, or the optional LCD display (which lets you check status and tweak settings on-site). Built-in diagnostics catch wire breaks and sensor faults, so you can fix issues fast without guessing. Backed by ABB’s global service network, the ABB TSP131 temperature sensor is that sweet spot—affordable, reliable, and packed with the right tech without being overcomplicated. Whether you’re replacing an old sensor or setting up a new system, it’s a solid choice for mid-range industrial temperature monitoring.
