Pressure switches are actuated by a change in the pressure of a liquid or gas.  They activate electromechanical or solid-state switches upon reaching a specific pressure level.

Web tension sensors are used to measure static or running tension in webs or sheets during the manufacture of textiles, paper, and other sheet materials.

Sensor and instrument coolers, cryostats and dewars enhance sensitivity or allow sensors to function in demanding, high-temperature environments.

Industrial ovens are batch or continuous process enclosures or tunnels that are insulated and used for thermal processing. Ovens are lower temperature (usually < 1400° F) thermal processing units, usually without refractory insulation.

Laboratory ovens are used in a variety of thermal processing applications including general lab work, component and stability testing, core hardening, drying glassware, and sterilizing. 

Vacuum ovens are heat-treating ovens that use a low atmospheric pressure instead of a protective gas atmosphere. This helps to alleviate surface reactions. 

Laboratory furnaces provide continuous heating to process samples and materials.

Industrial furnaces are built of several kinds of high temperature (refractory) materials to hold the process material and hold in the heat without breaking down during the several months that they usually run. 

Vacuum furnaces are heat-treating furnaces that use a low atmospheric pressure instead of a protective gas atmosphere. This helps to alleviate surface reactions.

Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes. They are typically used to control heating and cooling systems.
