In brief

A wide range of sensors, available materials, microswitches and approvals make the 120 series almost suitable for any application in an explosion-hazardous environment, ensuring safety, alarm or lockout intervention. Models with a single SPDT microswitch have dual cable inputs, allowing the choice of the most convenient connection. The line has sensors for direct mounting to the thermowell with options for extension in bulb length, while capillary instruments can be supplied with either stainless steel armor or PTFE coating to the full length of the capillary. Capillaries have no modular length but can be chosen for any length needed.

There is a choice of models with one or two independent SPDT microswitches and internal or externally protected, double-scale regulation. Microswitches of various features can be supplied, including models with 20A or 30A rating on the contacts. Many certifications, for use in Europe, Eurasian Confederation, South Korea, China, Ukraina, NorthAmerica, Canada, Brazil, India, UAE and all countries that recognize IECEx International certification. SIL approval makes them suitable for use in Safety Instrumented Systems (SIS).
