Low-Power Level Transmitter Overview
The HPM410LV is a low-power submersible level transmitter that converts liquid hydrostatic pressure into a proportional voltage signal. It is designed for remote monitoring points, IoT terminals and battery-supported data acquisition systems that require a lower supply voltage and current consumption than a conventional industrial current-loop transmitter.
Available measuring ranges extend from 0–0.5 mH₂O to 0–10 mH₂O. Standard voltage-output choices include 0.25–1.25V, 0.25–2.25V and 0.5–2.5V, with other voltage ranges available for project evaluation. The transmitter operates from a 3.1–8VDC supply and has a working current below 2.5mA.
The sensor is lowered into the liquid and measures the pressure generated by the liquid column above its sensing diaphragm. A signal-conditioning circuit converts this pressure into a voltage that can be read by a data logger, telemetry controller, ADC input or compatible wireless terminal.
Correct selection depends on the required level range, liquid density, cable length, wetted-material compatibility, power source and input range of the receiving device. These details should be defined before calibration and cable assembly.
HPM410LV pressure transmitter stands out with its low power consumption, making it an energy-efficient solution for long-term operations. With its high-quality pressure sensor, this transmitter ensures accurate and stable measurements, allowing for precise monitoring and control of liquid levels.
Product Advantages
Low-Voltage Operation
The 3.1–8VDC supply range supports systems built around low-voltage controllers and external lithium batteries. This makes the HPM410LV suitable for monitoring stations where mains power is unavailable or where the sensor is integrated into a larger energy-managed device.
Working Current Below 2.5mA
The specified working current is less than 2.5mA. Actual battery service time depends on battery capacity, battery chemistry, temperature, voltage regulation, sampling strategy and the current drawn by the wireless module or data logger. Battery life should therefore be calculated for the complete monitoring system rather than from the transmitter current alone.
Multiple Voltage Outputs
Three stated output options—0.25–1.25V, 0.25–2.25V and 0.5–2.5V—allow the transmitter to be matched to different analog input ranges. Keeping the output above zero at the lower endpoint can also help the controller distinguish a valid zero-level signal from some wiring or supply faults, subject to the system design.
External Battery Integration
An external lithium battery can be used when its voltage, capacity, protection circuit and discharge behavior meet the transmitter and system requirements. The HPM410LV does not contain a wireless radio; it provides the measurement signal that a compatible telemetry or IoT module can acquire and transmit.
Anti-Condensation Design
The product includes an anti-condensation design intended to reduce moisture-related measurement problems. The cable termination and atmospheric reference path still require appropriate protection because condensation or water entry at the dry end can affect a vented hydrostatic transmitter.
Configurable Production
Output range, measuring range, cable length and other project details can be reviewed for customization. The approved quotation and model configuration should identify every deviation from the standard parameters.
This transmitter is suitable for use in a wide range of industries, including oil and gas, chemical, water treatment, and pharmaceutical. Its robust construction and technology make it resistant to harsh environmental conditions, ensuring durability and longevity in demanding industrial settings.
