The E+H Omnigrad M TW11 Protection Tube is designed for use in the fine chemicals industry and generally for almost all industrial processes. This protection tube is an important component for temperature measurement points for almost all industrial processes, especially for fine chemicals industries. It is used to protect the measuring insert or sensor elements from aggressive process media, high pressures and flow rates from the temperature sensor itself and thereby enables the thermometer to be exchanged during operation.
