Bimetal temperature measurement products expanded for sanitary applications

July 27, 2009
The manufacturer has added bimetal thermometers and thermowells for general industry to its product offering. The 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 -100 to 1000°F (-70 to 540°C) and are available in adjustable-angle, center-back, and lower-back mount process connections. Every thermometer is factory calibrated. In addition, the products feature external reset for field calibration. 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. 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. The 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.
