The SNiP-SPT is a 'Sensor Node Integrated Package' for LoRaWAN communication of real-time water level and temperature measurements for continuous environmental monitoring.
The base SNiP-SPT integrates 1x AD-NODE and 1x ECL-8438 Submersible Pressure Transmitter to a site’s unique network, communication and power requirements.
The ECL-8438 water level instrument ensures a high level of accuracy over a wide temperature range.

The AD-NODE is designed for those requiring precision in their analogue and digital measurements. With a 24-bit ADC, the AD-NODE supports two RTDs, a 0–10V with compressing range and a 4–20mA input. Each of the four dry-contact digital inputs is capable of simultaneously sampling at 1 kHz, with periodic reporting. Settings on the device can be altered remotely via LoRaWAN™ or locally via USB.
The Submersible Pressure Transmitter ECL is based on Trafag’s own thick-film-on-ceramic technology. Together with the inhouse developed high performance ASIC chip electronics it ensures a high level of accuracy over a wide temperature range.
