Temperature nodes

Banner Engineering has released analog thermocouple and RTD instrumentation nodes for the SureCross wireless network.

Designed and purpose-built for SureCross, the 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 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, demonstrating an extensive 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 temperature sensing suitable for a wide variety of applications.

The RTD node supports up to four 3-wire 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 network and are housed in an IP67 housing. Both 900 MHz and 2.4 GHz frequency communication models are available.

In addition, with FlexPower, the nodes can be powered by 10-30 V or 3.6-5.5 VDC power, solar power or 3.6 V FlexPower battery module.
