HR8008 Ceramic Capacitance Input Water Level Gauge

1. Overview

The HR8008 series of ceramic capacitive immersion-type intelligent water level and temperature gauges are high-precision pressure-based instruments designed for long-term monitoring of surface water or groundwater levels and temperatures. These products utilize ceramic sensing elements with excellent stability, high accuracy, and strong overload capacity. They employ advanced mixed-signal processing technology, enabling full-scale digital linear calibration and digital temperature error compensation across the entire temperature range. The compensation parameters are stored in non-volatile memory, ensuring multiple safety protection mechanisms to prevent the loss of calibration parameters that could render the product unusable. The circuitry includes power supply monitoring and watchdog monitoring functions, effectively preventing system crashes and program malfunctions, greatly enhancing product reliability.

These gauges are available in a wide range of models and find extensive applications in measuring surface water level and temperature as well as groundwater level and temperature.
