Electronics/Controller Unit for Vacuum Gauges

Product Specifications

Technical details and manufacturing context for Electronics/Controller Unit

Definition

The electronics/controller unit is the core processing component of a vacuum gauge system. It manages sensor inputs, controls measurement functions, processes vacuum pressure data, and interfaces with external systems for monitoring and control applications. This unit receives analog or digital signals from vacuum sensors, processes the data through embedded algorithms, converts measurements to readable formats, controls display functions, manages communication protocols, and provides control outputs for system integration. Typical materials include a printed circuit board (PCB), semiconductor components, and electronic connectors. Key parameters include a supply voltage of 24 V DC ±10% (reverse polarity protected), power consumption ≤5 W at nominal voltage, analog output of 4–20 mA (isolated, load ≤500 Ω), digital interface RS-485 with Modbus RTU protocol, measurement range from 1×10⁻⁵ to 1×10⁵ Pa (full scale accuracy), accuracy ±0.5% of reading at 23 ±5 °C, operating temperature -20 to 60 °C (non-condensing), storage temperature -40 to 85 °C (without battery), ingress protection IP54–IP65 (IP65 with mating connector) per IEC 60529, housing material aluminum (powder coated), weight ≤0.5 kg (without cable), and dimensions 100×60×30 mm (W×H×D, without connectors). These values are directory reference ranges and must be confirmed for the actual model and application. The unit is intended for use in vacuum systems where precise pressure measurement and control are required. It is not a standalone product but a component that integrates with vacuum sensors and external systems. For selection, verify compatibility with your sensor type, communication requirements, and environmental conditions. Always check the legal manufacturer's specifications for the specific model to ensure compliance with your application's requirements.

Working Principle

The electronics/controller unit operates by receiving analog or digital signals from vacuum sensors. These signals are processed through embedded algorithms that convert raw data into pressure readings. The unit then formats the data for display and communication, using protocols such as Modbus RTU over RS-485. It also provides control outputs for system integration, allowing external devices to respond to pressure changes. The unit manages its own power supply, ensuring stable operation within specified voltage and temperature ranges. It is designed to handle a wide measurement range, from high vacuum to atmospheric pressure, with high accuracy. The unit's housing provides protection against environmental factors, and its connectors ensure reliable electrical connections.
