New source for industrial bimetal thermometers and thermowells

Paul Boughton
Swagelok is now supplying industrial bimetal thermometers and thermowells. These products expand the company'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 degrees C (-100 to 1000 degrees F) 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 an external reset for field calibration.

Bill Menz, market manager for process instrumentation at Swagelok, states: "Our customers depend on Swagelok products to provide high-integrity measurement and tighter process control of their systems. The addition of thermometers and thermowells for general industry is a natural complement to our existing product line."

Swagelok says the bimetal thermometers are accurate to +/-1 per cent 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.

The industrial thermowells are designed to protect the thermometers from contact with viscous, pressurised, corrosive or abrasive process fluids. They also enable thermometers to be removed for replacement or service without affecting the process or system.

Swagelok thermowells feature standard 304 stainless steel construction or 316 stainless steel upon request. The products are 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 2 inch sizes. Thermowells for sanitary applications are 3-A compliant.
