Baumer has released its O200 photoelectric miniature sensors. The O200, equipped with an IO-Link interface, is suited for the detection of objects in confined spaces. With their ambient light immunity and precise, reproducible and color-independent switching distances, these photoelectric miniature sensors maintain their reliability even in harsh conditions.

E+E Elektronik has launched its EE820 sensor, designed to monitor the CO2 concentration in harsh and polluted environments. Beside voltage and current output, the sensor is also available with an RS485 interface with Modbus RTU or a BACnet MS/TP protocol.

The operation of the EE820 is based on the E+E Elektronik’s dual-wavelength NDIR principle, which is insensitive to contamination and automatically compensates for ageing effects. The multi-point CO2 and temperature factory adjustment procedure ensures high CO2 measurement accuracy over a temperature range of -20 to 60 °C.

FLIR Environmental Meter

FLIR has developed its EM54 environmental meter for heating, ventilation, air conditioning and refrigeration (HVAC/R) measurements. The EM54, based on hygrometer technology, identifies deviations from ambient relative humidity levels, which can cause static hazards at manufacturing sites and discomfort in homes and offices. This meter also helps users quickly and accurately identify symptoms of clogged HVAC/R filters, duct leaks that reduce airflow and overloaded systems.

ifm has introduced its wpi 631 thermal SD compressed air sensor, which is suited for the identification of leakages in compressed air systems. The sensor measures air pressure as well as the temperature and the volumetric flow, meaning that it can also be used as a quantity meter.

With the flow rate measurement, compressed air consumption can be directly allocated to different applications or production lines. This allows for the optimization of cost calculation and an increase in efficiency with regard tp energy management systems.

Sensata Technologies has unveiled its ACW4 single turn and TCW4 multi turn absolute hall effect sensors, which feature an over-molded, two-part modular construction. The sensing electronics are encased in a thermoplastic polyamide shell while the activating magnet is external to the sensor assembly.  This modular architecture results in a package of 50mm x 24mm that allows designers to incorporate the ACW4 and TCW4 sensors into both new and existing systems.
