Mô tả sản phẩm
Description
This series of thermometers has been designed as an addition to the standard range of thermometers in order to meet the special requirements of the food, bio and pharmaceutical industries as well as in the paints and varnishes industry.
The model 74 gas-actuated thermometer is ideally suited to fulfil the high standard requirements of sanitary applications. Based on a third party verification, the thermometer complies with the 3-A standard 74-03 and is marked by us accordingly.
Stem and case are made of stainless steel. The surface of the wetted parts is polished, and a wide variety of process connections is available to ensure the optimal adaptation to many different process requirements. The stem is free of dead space.
Switch contacts (electrical alarm contacts) make or break an electric control circuit dependent upon the position of the instrument pointer. The switch contacts are adjustable over the full measuring range.
The instrument pointer actual value pointer) moves freely across the entire scale range, independent of the setting. The set pointer can be adjusted via the window using a removable adjustment key (mounted on the terminal box).
Switch contacts consisting of several contacts can also be set to a single set point. Contact actuation is made when the actual value pointer travels beyond or below the desired set point.
For switch contacts, sliding and magnetic snap-action contacts, reed contacts, inductive contacts - for requirements to ATEX - or electronic contacts for PLC switching are available.
