Technical overview
The WIKA S5551 bimetal thermometer is a robust process instrument for accurate local temperature indication in demanding industrial service. Built in accordance with EN 13190 and designed for harsh and aggressive environments, it offers an all-stainless-steel construction suitable for chemical, petrochemical, oil and gas, energy, and water or wastewater applications. This version features a 0 ... 400 °C dual-scale dial, 6" dial size, back connection with 360° adjustable stem, 1/2" Male NPT process connection, and 350 mm stem length, the adjustable stem and dial arrangement helps align the viewing angle after installation for easier reading in confined or offset mounting positions.
Note: The pointer reading seen in the product images is because the bimetal thermometer begins indicating temperature as soon as the stem is exposed to its surroundings. Therefore, a reading above zero is normal even for a new/unused product. This also confirms that the thermometer is functioning properly.
