Instant install, accurate temperature sensors from Shibaura

Shibaura JXW-51 temperature sensor rangeShibaura’s JXW-51 temperature sensor range offers a durable, accurate solution for boiler, water heater and pipe flow applications. With multiple mounting brackets available, JXW-51 sensors are widely used in wall-mounted boiler and dual-purpose stove applications. The sensor can be instantly added to both existing systems and new designs thanks to its clip on design, providing direct access to accurate temperature data from -40°C to 120°C.

With an International Protection Rating of IP54, every JXW-51 is protected against dust, humidity and water exposure*, and, with high stability, it is the ideal solution for fit-and-forget designs. Plus, with its clip on design, installation is instant whilst remaining flexible around an existing design.

Shibaura offers the JXW-51 in a range of sizes from 12mm to 18mm, with both single and duplex types available. Within the sensor, Shibaura NTC elements from the PSB series provide temperature data within an accuracy of less than ±1°C. Once fitted, systems benefit from the low response time of less than 3seconds at the contact point, which is constructed out of a durable nickel plated copper.

Pipe-style mounting brackets are available in multiple designs, including the popular circular clip, which are made out of either stainless or manganese steel. Shibaura also offer custom designed solutions, with JXW-51 sensors tailor-made to customer applications, providing all the benefits of the standard range with the additional convenience of a custom solution.

Compared to standard immersion type sensors, these clip of sensors are less susceptible to corrosion, wear and failure, and are easily replaceable for extended product life, providing customers a cost benefit over immersion equivalents throughout the product life cycle, including design, manufacturing and service phases.
