The new SureCross sensor is factory-calibrated to determine relative humidity to ±2% or ±3,5% (depending on model) and delivers temperature accuracy to ±0,3°C for simple critical data monitoring. Manufactured with a rugged metal housing and IP67 electronics, it provides maintenance-free operation in a wide variety of environmental monitoring applications.
Versatility
Banner designed a proprietary serial sensor interface that enables the temperature and humidity 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 wide range of installation scenarios, including in-duct and freestanding applications. For remotely mounted sensors, cables in lengths up to 3 metres are available. A hydrophobic membrane filter for general applications and a sintered stainless steel filter for hostile drying areas are available to meet the requirements of the most 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 d.c.. With an external power supply, two temperature and humidity sensors can be used with a single wireless node. Each node is equipped with an LCD and temperature can be displayed in Celsius or Fahrenheit; relative humidity is in a percentage from 0-100%. The node can be installed as a standalone device, or it can work in conjunction with a gateway, the wireless network controller. The SureCross Wireless Network provides a robust, reliable wireless solution with bidirectional fully acknowledged data transmission. This network employs frequency hopping spread spectrum (FHSS) and time division multiple access (TDMA) to ensure the most reliable data delivery possible. The gateway supports multiple communication outputs and seamlessly integrates with existing wired control systems.
Reliability
If radio frequency links are lost, all relevant outputs can be set to user-defined conditions until the links are re-established. This deterministic wireless capability makes the products simple to install and more cost-effective than conduit, delivering a reliable, long-lasting solution.
“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 integrity-ensured SureCross Wireless Network, and users can select the power method that works best for their individual applications.” Dales adds, “With this arrangement, if temperature or humidity exceed acceptable limits, a remotely located gateway can issue an alarm to management personnel, minimising the risk of product damage or loss.”
Applications
The SureCross Wireless Network equipped with the serial sensor interface and factory-calibrated temperature and humidity sensors deliver dependable monitoring in a broad range of environments, including:
* Large-scale refrigeration and cold chain storage systems.
