Ashcroft DURATEMP-20-240F Gas Actuated Thermometer

Ashcroft Duratemp Gas Actuated Thermometer, model DURATEMP-20-240F, is a rugged process-instrument indicator designed for high-vibration environments. This 4-1/2" dial thermometer uses a gas-actuated, movementless mechanism (no gears to wear or misalign) and a 20' capillary, offering a 20°F to 240°F reading window with electrical contacts for integration with controls. The Duratemp family can be mounted remotely or directly on panels, with Ashcroft documenting both C-600A remote-mount and 600B direct-mount configurations to suit installation needs. The Duratemp line spans a wide temperature range overall—from -320°F to 1200°F (-200°C to 650°C)—demonstrating its applicability across hot-process and industrial environments, while the 20/240°F variant targets low-to-mid-range applications such as monitoring air, gas, or liquid streams in systems requiring simple, reliable indication plus optional switching.
