Wireless temperature nodes

Banner Engineering Corp has announced analog thermocouple and RTD instrumentation nodes for the SureCross wireless network. Designed and purpose-built for Banner’s SureCross wireless network, these nodes are available in versions to support thermocouple/thermistor inputs and 2-, 3- and 4-wire RTDs. They facilitate easy, rugged wireless temperature sensing for high repeatability and fast response time, requiring no calibration by the user.

The SureCross thermocouple node supports up to three thermocouple inputs, one thermistor input and two discrete (sinking) inputs and has two discrete (NMOS sinking) outputs. Users can choose from 11 configurable thermocouple options, providing a temperature sensing range from -200 to +2320°C, depending on configuration. The node defaults to the J-type thermocouple, which senses temperatures ranging from -180 to +750°C and offers a plug-and-play solution suitable for remote or difficult to access locations. In addition, the thermocouple node uses integrated cold junction compensation to provide reliable temperature sensing suitable for a wide variety of applications.

The RTD node supports up to four 3-wire Pt100 (DIN.00385) RTDs and offers a temperature sensing range of -200 to 482°C. Additional temperature sensing types are available.

Nodes work in conjunction with a gateway on the SureCross wireless network and are housed in a rugged IP67 housing. Both 900 MHz and 2.4 GHz frequency communication models are available, providing advanced wireless temperature sensing capabilities from practically anywhere. In addition, with Banner’s innovative FlexPower capability, the nodes can be powered by 10-30 V or energy-saving 3.6-5.5 VDC power, solar power, or Banner’s 3.6 V FlexPower battery module.
