Overview

Nexisense LoRa wireless submersible level transmitter is a wireless level monitoring device with LoRa self-organizing network as the core, which can transmit parameters such as level and temperature in real time. At present, Nexisense has formed mature product lines such as LoRa wireless level transmitter, LoRa wireless temperature transmitter, and LoRa wireless temperature and level integrated transmitter, and is expanding series such as LoRa radar level gauge and LoRa ultrasonic level gauge.

The transmitter adopts a high-precision diffused silicon core (strain core optional for special occasions), with an explosion-proof shell design. The large LCD screen can simultaneously display the current level value and ambient temperature. The level is compensated in real time by collecting ambient temperature to ensure high-precision measurement in a wide temperature range of -10℃~60℃. The product is powered by a large-capacity 3.6V lithium battery and transmits data wirelessly. There is no need for on-site wiring, truly realizing plug-and-play, and later maintenance is extremely convenient.

Based on mature digital level technology, Nexisense deeply integrates LoRa low-power wide-area network technology, strengthening anti-interference capability and system integration features. System integrators can realize remote collection, trend analysis, and alarm linkage of level data through LoRa gateways or direct access to the cloud platform; engineering contractors can quickly deploy in fire protection, water supply and drainage, petrochemical, river and reservoir, sewage monitoring and other projects to ensure the visualization, controllability, and high reliability of the level process.

This series of wireless level transmitters features high precision, strong stability, outstanding anti-interference capability, low power consumption, and convenient installation and maintenance. It is the preferred equipment for level monitoring in industrial sites and remote areas.

Wiring and Installation

This product is a wireless battery-powered device and does not require on-site power wiring. Installation tips are as follows:

• Use M20×1.5 external thread (or customized flange/thread). The submersible probe is placed vertically into the measured medium to ensure the probe is fully submerged and does not touch the bottom of the container.

• Install the transmitter body in a position convenient for observation and maintenance, and fix it securely.

• Perform zero calibration and range setting after power-on (supports infrared, button, or cloud debugging).

• It is recommended to preheat and check signal strength for the first use to ensure good LoRa network coverage.

• Regularly check battery power and probe cleanliness, and arrange maintenance cycles according to the use environment.
