Chongqing Chuanyi WSS-415-P0-150-6A100-AM20 Bimetallic Thermometer
WSS-415-P0-150-6A100-AM20
Engineered for rugged environments, this high-precision radial mount bimetallic thermometer delivers accurate, real-time mechanical temperature readings without external power. Featuring a durable 304 or 316L stainless steel case with IP65/IP66 protection, customizable probe dimensions, and optional silicone oil filling for high-vibration applications, it serves as an ideal direct-replacement solution for industrial pipeline and vessel temperature monitoring across oil, chemical, and power industries.
The WSS series radial bimetallic thermometer represents a reliable, field-proven mechanical temperature measurement solution engineered for demanding industrial environments. Operating on the principle of differential thermal expansion between two fused metal strips, the internal helical sensing element drives the pointer axis smoothly to deliver accurate, real-time temperature readings on a high-contrast dial face without requiring external electrical power. Constructed with a heavy-gauge 304 or 316L stainless steel case, seamless stem tubes, and an IP65/IP66 weatherproof structure, this bottom-entry radial thermometer offers superior resistance to mechanical shock, chemical corrosion, and environmental degradation. To handle high-vibration equipment, the housing can be liquid-filled with silicone oil to dampen pointer movement and extend operational life. Designed to accommodate various process demands, it supports custom stem insertion lengths, multiple thread/flange mounting options, three-color dial customization for visual temperature thresholds, and complete integration with heavy-duty thermowells for high-pressure, high-velocity, or abrasive media installations.
FAQ
Q: What is the main advantage of a radial (bottom entry) bimetallic thermometer?
A: A radial mount thermometer features a dial face positioned parallel to the sensor probe, making it ideal for eye-level reading on vertical pipelines, vessel walls, or machinery where top-mounted (axial) dials are difficult to view.
Q: Can this thermometer be used in high-vibration applications?
A: Yes. For environments exposed to continuous mechanical vibration or pressure pulsations, we offer a liquid-filled option silicone oil filled inside the case to damp pointer movement, prevent internal mechanism wear, and ensure stable readability.
Q: How do I select the minimum insertion length for accurate readings?
A: To prevent measurement errors caused by heat dissipation along the stem, the temperature-sensing coil must be fully submerged in the medium. Recommended minimum insertion lengths vary by temperature span and stem diameter—for example, a minimum insertion depth of 60 mm is recommended for a 0–100°C range with an 8 mm probe stem.
Q: Do you supply matching thermowells for high-pressure or corrosive fluids?
A: Yes, we provide a full range of thermowells including threaded (BL series), flanged (BF series), and bar-stock drilled (BH series) in 304, 316L, 321, or specialized anti-wear alloy coatings to protect the thermometer probe against high pressures, high flow velocities, and corrosive substances.
Q: Is customization available for OEM or private label branding?
A: As an experienced automation instrument manufacturer, we support full OEM customization including customized dial scales, dual-unit temperature markings (°C/°F), three-color warning dial prints, custom process connection threads (NPT, BSP, Metric), and personalized logo printing.
