Instructions

·The standard material for protective tubes, extension tubes, and process connections is stainless steel 1.4301. For other stainless steel materials, please consult our sales staff and indicate them when selecting;

·For special ranges or the use of other temperature sensing components such as Pt500, Pt1000, etc., please consult our sales personnel and specify when selecting;

·When choosing a module with a temperature transmitter, please indicate the temperature range of the transmitter. We will help you set it up together when it leaves the factory;

·The process connection is a flange connection. Please provide flange drawings and relevant standards.
