Capacitance Level Transmitter Board
Description :
The H509 capacitive level transmitter board serves as the core component of a level gauge. It is a measuring instrument used in the construction of level gauges that are designed to determine the height of liquids or solid materials. This transmitter board is suitable for a wide range of industrial scenarios, including petroleum, chemical engineering, food, pharmaceuticals, water treatment, and natural gas industries.
Parameters
The high feauters of the transmitter board are listed below
- High Precision: Achieve high precision through Direct Digital Synthesis (DDS) technology.
- Full Isolation: With an isolation voltage of up to 1000VDC between the sensor and the main circuit.
- Wide Measuring Range: The H509 currently employs a capacitive measurement structure, with a measurement range of 50PF to 5000PF and a resolution of 0.002PF.
- 3 buttons complete all functions: It has a comprehensive three-button field calibration feature (compatible with two-button mode and supporting reed switches), enabling functions such as span, zeroing, damping, and data recovery.
- Full-view LCD display: Equipped with an emerald green backlit multifunctional LCD display that can simultaneously display up to four variables and is rotatable by 360 degrees.
- Free of field maintenance: It possesses a complete data backup and recovery function
- long-term stability: The modular design ensures high reliability, consistency, and long-term stability of the product.
