| Thermowells protect sensors from the effects of fluid flow and pressure. These assemblies are spring-loaded for positive probe contact against the bottom of the thermowell.The probe's copper alloy tip provides superior time response and reduces error from stem conduction. • 316 stainless steel thermowell • Tip-sensitive thermocouple for use to 260°C (500°F) • Spring-loaded probe • Cast iron, stainless steel, or aluminum connection head Specifications Temperature range: -50 to 260°C (-58 to 500°F).
