Take a look at these sensor technologies from CIEN, PLANT’s technology section.
High accuracy for food processing
Baumer’s OADR 20 laser sensors are highly accurate with resolutions from 5 µm. They’re encased in a stainless steel housing that features Baumer’s proTect+ to comply with IP68/IP69K, even after repeated temperature cycles in washdown applications.
The photoelectric sensors, which detect food items or packages on conveyor belts, come in standard models and in a SmartReflect version with a light barrier that operates without a reflector and has a sensing distance of 800 mm.
PEEK plastic sensor tips that protrude only 18 mm into the container or tube avoid flow blockage and handle temperatures between -40 to 115 degrees C.
The Baumer Group is a sensor manufacturer with operations in Burlington, Ont.
Monitor demand and supply for critical applications
CONCOA’s CryoWiz switchover is used for cryopreservation applications and environmental chambers that automatically deliver a continuous supply of liquid nitrogen with little to no variation in temperature or state.
The fully automatic CryoWiz uses a proprietary algorithm, precise pressure and temperature sensors, and dynamic hot-gas bypass to maintain a specified temperature with maximum consumption efficiency. “Keep-full” and “on-demand” operation modes are customizable to specific cryogenic application.
The unit eliminates temperature spikes and low liquid level alarms in freezers, which combined with the ability to determine when the primary supply is truly empty, provides for cost efficiency. It has a 24,000-event log with built-in battery backup and can be ordered with a web server to remotely monitor cryogenic supply and send e-mail notifications of system status.
CONCOA is a manufacturer of pressure gas and flow control equipment based in Virginia Beach, Va.

WTB4 MultiLine Photoelectric sensors from SICK USA use optics to create two line-shaped light spots that continuously detect objects with large gaps (such as PCBs and products that are shiny or dark) from leading to trailing edge in a range of packaging and semiconductor applications.
Both light sources must reflect the light back to the sensor to activate the output. Once they’re returned, the sensor stays active even if one of the light beams is not returned.
Using two light streams minimizes downtime caused by incorrect detection from single point sensors.
SICK’s ASIC technology incorporates OES3 to boost background suppression and allow the sensors to ignore shiny targets, detect multi-coloured objects and enhance ambient light immunity.
SICK, based in Minneapolis, manufactures sensors, safety systems and automatic identification products for industrial applications.
SJ-301 improves surface testing
RESOLUTE UHV ultra-high vacuum encoders from Renishaw Inc. deliver absolute position feedback, sub-micron accuracy and resolutions to 1 Nm for both linear and rotary applications.
They’re made from clean vacuum-compatible materials and adhesives with low out-gassing rates. Based on proven clean residual gas analysis (RGA), they’re suitable for high performance, semiconductor and scientific applications that require vacuum compatibility to 10-10 Torr.
Switch it on and the ultra-high vacuum variant immediately determines position. Instant commutation means axes are under control after power loss to eliminate unchecked movements or collisions, which is an advantage in applications such as wafer handling.
The encoders eliminate auxiliary 1 Vpp signals, provide higher noise immunity and detect data corruption. A range of serial protocols include BiSS, FANUC, Mitsubishi and Panasonic.
Renishaw is a developer of measurement and motion control technologies based in Glouchestershire, UK. The company has a Canadian office in Mississauga, Ont.
Long sensor range detects magnetic fields
MFxM proximity switches from Baumer detect magnetic fields over distances up to 60 mm where the target is behind a wall of non-ferromagnetic metal, such as stainless steel or aluminum. MFxMs replace inductive sensors where long distance influences the detection of magnetic fields.
A large sensing range increases tolerance to compensate for objects subject to rocking motion. Compact rectangular housings measuring 8 x 8 mm, or standard M8 are available.
Baumer, based in Frauenfeld, Swizerland, is a manufacturer of sensors for process automation. It has a Canadian office in Burlington, Ont.
