Swagelok's bimetal thermometers and thermowells feature external reset for field calibration
Swagelok has added bimetal thermometers and thermowells for general industry to its product offering. The dampened-movement bimetal thermometers operate in measurement ranges from -100 to 1000°F (-70 to 540°C) and are available in adjustable-angle, center-back and lower-back mount process connections. In addition, the products feature external reset for field calibration.
The dampened-movement bimetal thermometers are accurate to ±1% of full scale in accordance with ASME B40.200 and are actuated by a sensitive bimetal helix coil. Silicone-free gel in the thermometer stem dampens vibration effects. To prevent fogging and moisture damage to working components, the dials are hermetically sealed. Swagelok thermowells for general industry are designed to protect the thermometers from contact with viscous, pressurized, corrosive or abrasive process fluids. They also enable removal of thermometers for replacement or service without affecting the process or system. Swagelok thermowells feature standard 304 stainless steel construction and 316 stainless steel upon request. The product is available in straight, reduced and tapered shaft designs. Instrument connections include 1/2-inch female NPSM straight and female G1/2B connections. Process connections include flange, sanitary clamp, threaded and weld socket in 1/2- to two-inch sizes. Thermowells for sanitary applications are 3-A compliant.
