Overview

HPM410LR low power consumption level transmitter uses high quality stable pressure sensor as the measurement element; it measures the static level pressure accurately which has direct ratio with liquid depth. Then converting the measurement value into standard RS485 signal through the signal conditioning circuit to achieve the measurement of liquid depth. This product has extremely low power consumption and long service life, it can use lithium-ion battery as power supply. And can connect wireless module, implement data wireless transport.

With long-term aging and stability testing, the product is suitable for harsh outdoor environment and can be widely used for groundwater, rivers, lakes, surface water tanks, and inventory water tanks. It is also suitable for kinds of measurement levels in IoT.

Features

Low Power Consumption
Easy adapted with wireless module
Can equip lithium battery outside as supply.
Common regular profile, easy to install.
Special Anti-condensation design
Customized requests supported.
