STEGO Inc. introduces smart sensor for condition monitoring

The STEGO Inc. Smart Sensor CSS 014 measures two important parameters — temperature and humidity — and helps to maintain an optimal climate for enclosures and switch cabinets, according to a press release.

The sensor supports condition monitoring, which applies not only to enclosures and switch cabinets in industrial plants, but also to a large number of different applications in which regulated processes take place.

The permanent measurement of temperature and humidity in the switch cabinet is an important element in preventing condensation, which leads to corrosion and thus failure of components.

The CSS 014 Smart Sensor combines three functions — sensor, interface and transmitter — in one compact device. The sensor measures ambient temperatures with high sensitivity within a range of -40 to +60 degrees Celsius while keeping a close eye on the relative humidity range from 0 to 100 percent.

The unit transmits the data it acquires as a standardized analog 4-20 mA signal. This allows users to further process and convert the measured values within a control or monitoring unit, e.g., a PLC.

Due to high measuring accuracy and signal strength, connection wires with a maximum length of 30 meters can be used. Thus, scenarios beyond the classic control cabinet application can be implemented. In principle, any larger, spatially sealed application with a defined atmosphere is suitable.

The sensor unit of the CSS 014 is thermally decoupled and encapsulated with a circumferential seal. This provides a high vibration resistance and compliance with the IP20 degree of protection.

The protective lacquer-coated board of the CSS 014 incorporates microcontrollers, interface drivers and EMC protection units in a heat-optimized arrangement so that any influence on the measured values due to waste heat is ruled out.

A shielded M12 round plug ensures a fast connection and safely transmits the signals of the two measuring channels for processing. The operating voltage is DC 24 volts (DC 12–30 V) with a maximum power consumption of 1.8 watts (typically 0.4 W).
