A new low-temperature cut-out and averaging sensor helps prevent low-temperature damage in industrial environments.
The solid-state Chill-Out sensor, from Minco and available through Mod-Tronic Instruments, senses freezing temperatures within any 12-inch section along its length. It replaces fragile and difficult-to-install gas capillary tubes and their mechanical switches. Unlike the capillary tubes, this sensor can be installed horizontally or vertically, or easily formed to fit any shaped system.
The sensor elements are available in a variety of styles, including bendable aluminum tubing and ultra-flexible brass armour. The electronic shut-off control can be mounted at the measuring point or within a central control box for convenient monitoring. An LED on the control box indicates a tripped condition, and a manual reset button allows the operator to quickly reinstate the system.
Standard models have a 41 degree F set point with a DPDT relay, though custom models can be ordered with any required trip point.
Chill-Out features two sensors in one package — a solid-state low-temperature cut-out (”Freeze Stat”) and an averaging resistance temperature sensor. The solid-state design and ⅜-inch diameter tubing eliminate concerns of gas leaks or kinking the capillary during installation.
