The SPI series sensors are designed for temperature measurement in industrial environments; equipped with a welded protective housing, they are intended for use on pipes or tanks. They are available with a direct output or a 4–20 mA output • SPI (version with welded connection) • SPI RC (version with sliding connection) • SPI RT (version with swivel fitting) • SPI ER tapered tip (fast response version) • SPI TI with extension (high-temperature version) • SPI TI ER with extension and tapered tip • Interchangeable sensing element • Modular design tailored to specific applications • Application areas industrial processes tanks and piping machinery and equipment
