TemperatureOne™ Wireless Temperature Sensor
The patent-pending TemperatureSensorOne™, model TS1, is a ZigBee-Enabled temperature sensor used for wireless industrial temperature measurement. The battery powered TS1 has a special case design that gives technicians convenient access to the battery compartment for easy battery replacement.
Device Description
Measuring about 200 millimeters long, the patent-pending IntelliSensing TS1 is a compact, self-contained wireless temperature sensor. Highly accurate temperature measurements are transmitted wirelessly to a suitable base station such as the IntelliSensing BS1, and passed to a host system such as a PC or PLC. The internal battery powers the sensor for the entire calibration period of one year.
Advanced Sensing
Of the many detectors devised for temperature measurement, the configuration that offers the best stability with the lowest hysteresis, is one in which a platinum coil is supported inside the capillaries of a two or four-bore, high-purity alumina insulator. Either the use of cement to clamp one side of the coil to the capillary wall, or, preferably, the insertion of soft alumina powder to prevent the platinum coil from vibrating freely helps achieve good reproducibility in industrial applications. We utilize this wire-wound type, in which the platinum winding is partially or fully supported (application dependent) by a high temperature alumina powder inside a ceramic tube. This construction provides a detector in which stability, interchangeability, and accuracy are the highest available for industrial and scientific applications.
Integrated Data Acquisition
Signals are amplified, sampled and digitized into 24-bit words at a rate of up to 1 ksps. This is all accomplished using a precision mixed-signal microcontroller (MCU) which integrates an analog-to-digital converter (ADC) and a high-speed 8051-compatible CPU. Accurate measurements are passed to the wireless subsection for transmission.
Cutting Edge ZigBee
Our ZigBee wireless interface combines an ultra-low power IEEE 802.15.4 transceiver with ZigBee software to form a transparent wireless communication solution that has self-organizing and self-healing properties. This mesh network allows for ease of installation around obstructions, redundancy in communication paths, and longer range. The 2.4 GHz frequency band is suitable for worldwide use.
Capable Radio Hardware
The IEEE 802.15.4 Standard details the Physical Layer (PHY) and Medium Access Control (MAC) specifications, and offers the building blocks for different types of networking known as “star, mesh, and cluster tree.” Network routing schemes are designed to ensure power conservation, and low latency through guaranteed time slots. Communication redundancy is a unique feature of the ZigBee network layer, eliminating “single point of failure” in mesh networks. Key features of the PHY include energy and link-quality detection, and clear channel assessment for improved coexistence with other wireless networks. The MAC specifies automatic packet acknowledgement, provides options for transmission in a range of pre-selected time intervals, and supports 128-bit AES security. The MAC and ZigBee application software is implemented in a code-efficient microcontroller that communicates digitally with the sensor data acquisition hardware.
