The technical data can make the difference in choosing a product. When a manufacturer of household or heating or cooling appliances chooses which thermoregulator or safety limiter to buy and install, the attention to these aspects is even greater, because it can affect the entire assembly line and the final quality of the product.
Let’s see what are the most important characteristics of our products dedicated to the industry and how to read them. If, on the other hand, you want to know the technical characteristics of a room thermostat or chronothermostat, we refer you to this article.
The most important technical data in industrial thermoregulation
- Contact capacity: the maximum load that can be applied to the electrical contacts, depending on the equipment that is connected to the thermostat.
- Contacts: can be normally open (NO) or in changeover (exchange). If normally open, it means that the device commands only one function, while if in changeover it can regulate two.
- Stages: in models with more than one stage (usually 2), there are two contacts in exchange, that is, like having two thermostats in one, a precious possibility when two controls are necessary.
- Maximum head temperature: it is the maximum temperature that the “head” of the thermostat or limiter can withstand, based on where it will be housed inside the device.
- Maximum bulb temperature: this is the maximum temperature that the bulb can withstand in order to function properly.
- Bulb and capillary material: usually in copper, nickel-plated copper or stainless steel, depending on the type of application. To handle very high temperatures, the use of stainless steel is recommended.
- Capillary protection: usually in PVC, depending on the type of application, it protects the capillary, but does not affect the temperature detection.
- Capillary length: the longer the capillary, the wider the adjustable temperature range.
- Minimum radius of curvature of the capillary: it is the point beyond which the capillary must not be bent, to allow the liquid inside to flow freely
- Liquid: petroleum derivatives or synthetic liquids are usually used, depending on the temperature to be measured.
- Connection: usually faston, oriented in different positions according to the installation housing on the final product.
- INAIL: certification required in Italy, mandatory in case of installation in thermal power plants
- Approvals: indicates which standards and / or quality requirements the device meets. It’s very important, because the final certification of the product depends on the certification of all the installed parts, depending on the required requirement.
Each IMIT capillary thermostat is produced according to the highest international standards, certified by the numerous quality marks obtained over the years: CE, ENEC, PED, TUV, UL, CSA, EAC, DIN.
