Circuit Lab, in collaboration with Telstra, has designed and manufactured Temperature and Humidity sensors to meet the demanding requirements for the protection of their Fiber and Wireless networks.
Self-powered devices interfacing through the One Wire protocol and the Industry standard, 4 - 20mA, are part of the range of T series transducers manufactured by Circuit Lab.
Housed in a custom ABS case 63 x 29 x 20 and using an RJ45 socket for connection these devices are compact and easily deployed.
In addition, this series employs data and power protection circuitry minimizing damage through surges and polarity reversal.
Although designed exclusively for Telstra, these sensors have found application throughout the industry as robust devices and are ideal sensors for IoT applications.
The following table is a brief outline of the transducers in this series.
