Swagelok has announced the addition of bimetal thermometers and thermowells for general industry to its product offering. The products expand Swagelok’s existing line of temperature measurement devices, which includes thermometers and thermowells for sanitary applications.

The dampened-movement bimetal thermometers operate in measurement ranges from -70 to 540°C and are available in adjustable-angle, centre-back, and lower-back mount process connections. Every Swagelok thermometer is factory calibrated. In addition, the products feature external reset for field calibration.

“Our customers depend on Swagelok products to provide high integrity measurement and tighter process control of their systems,” said Bill Menz, market manager for process instrumentation.

“The addition of thermometers and thermowells for general industry is a natural complement to our existing product line.”

The dampened-movement bimetal thermometers are accurate to ±1 percent 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, pressurised, 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 in. female NPSM straight and female G1/2B connections.

Process connections include flange, sanitary clamp, threaded, and weld socket in 1/2 to 2 in. sizes. Thermowells for sanitary applications are 3-A compliant.
