The COLM ( Co ntec L iquid M easurement) level indicators and sensors can be used for almost all liquids. In the case of gases, the focus is on LNG or LPG. Contec offers level indicators and level sensors for special gases for the industrial or commercial vehicle sector (e.g. hydrogen). Solids, on the other hand, cannot be measured. Which measuring principle is used? The COLM level sensors and level switches use different measuring principles - depending on the requirement area or accuracy specification. Simple, inexpensive sensors on an electro-mechanical basis (e.g. reed switches), capacitive sensors and switches through to guided wave radar (GWR) sensors are part of the Contec product portfolio. What are mechanical level indicators used for? The mechanical level indicators are always used when there is no electrical connection or when a level is to be read without starting the engine (e.g. in commercial vehicles). Can the COLM level sensors be connected to BUS systems? Standard output signals in ohms, amperes or volts are available for almost every sensor and level switch. There are also retrofit kits for mechanical level indicators (type Twinsite). All that is required is to replace the display sheet. Depending on which BUS system is used, there are also already existing solutions (e.g. for LIN-BUS). If you use a special BUS system, please contact us. We would be happy to develop a solution together with you. Can the COLM level switches, sensors and level indicators be adapted to different requirements and specifications? We stand for "clean solutions". We would be happy to work with you to adapt a level indicator, a level sensor or a level switch based on your specification. In addition, we will be happy to accompany you in the context of a development project or a certification process and, upon completion, provide you with the relevant documents.
