Temperature, relative humidity sensors pair with wireless network
|Banner Engineering Corp. has announced SureCross Temperature and Humidity Sensor for use with the Banner Engineering SureCross Wireless Network.|
The product is factory-calibrated to determine relative humidity to
A proprietary serial sensor interface enables the sensor and the wireless node to operate on a FlexPower battery supply for up to 20 years. Fixed and remote-mount node and sensor models enable a range of installation scenarios, including in-duct and freestanding applications. For remotely mounted sensors, cables in lengths up to three meters are available. A hydrophobic membrane filter for general applications and a sintered stainless steel filter for hostile drying areas meet requirements of demanding environments.
The sensor can be paired with a node that includes an integral battery supply or an external power source including battery, solar, or 10-30 V dc. With an external power supply, two sensors can be used with a single wireless node. Each is equipped with an LCD; data is displayed in degrees C or F, and relative humidity is in a percentage from 0-100%. The node can be installed as a standalone device, in conjunction with a gateway, the wireless network controller. The SureCross Wireless Network provides a wireless solution with bidirectional acknowledged data transmission and employs Frequency Hopping Spread Spectrum (FHSS) and Time Division Multiple Access. The gateway supports multiple communication outputs, seamlessly integrating with existing wired control systems.
If radio frequency links are lost, all relevant outputs can be set to user-defined conditions until links are reestablished. The deterministic wireless capability permits simple installation and is more cost-effective than conduit.
“Monitoring the optimal temperature and humidity in controlled storage areas is crucial to ensuring optimum product quality — and if this environment is not sufficiently maintained, the stored products can quickly become compromised,” said Chris Dales, senior application engineer, Banner Wireless Division. “The Temperature and Humidity Sensor delivers highly accurate results that are simply transmitted using the communications-integrity-ensured SureCross Wireless Network, and users can select the power method that works best for their individual applications. With this arrangement, if temperature or humidity exceed acceptable limits, a remotely located gateway can issue an alarm to management personnel, minimizing the risk of product damage or loss.”
Applications include greenhouses, warehouse areas, pharmaceutical, HVAC, textiles, energy management, and IT resources and data centers. Features include relative humidity measurement withpabilities through a remote SureCross Gateway to inform management personnel when temperature or humidity has exceeded acceptable levels.
