YRZK-10S Vacuum Controller by Jinye (Shanghai Yarong Biochemical Instrument Factory)

Overview

The YRZK-10S Vacuum Controller is a precision-engineered electronic instrument designed for stable, real-time regulation and monitoring of vacuum pressure in laboratory-scale vacuum systems. Built upon proportional-integral (PI) control logic, it interfaces with common vacuum gauges (e.g., Pirani, thermocouple, or capacitance manometers) and drives vacuum pumps or throttle valves to maintain user-defined setpoints within defined hysteresis bands. Its architecture supports both manual override and closed-loop automatic operation, making it suitable for applications requiring repeatable vacuum profiles—such as rotary evaporation, freeze-drying, vacuum distillation, thin-film deposition, and inert-atmosphere sample handling. The controller complies with IEC 61000-4 electromagnetic compatibility (EMC) standards and operates reliably under ambient conditions of 5–40 °C and ≤80% RH non-condensing.

Key Features

• Integrated dual-channel analog input (0–10 V or 4–20 mA) for simultaneous connection to primary and backup vacuum sensors
• Programmable setpoint range: 0.1 Pa to 10⁵ Pa (absolute), scalable via front-panel keypad or external RS485 interface
• Real-time digital display with 0.1 Pa resolution and ±1.5% full-scale accuracy (calibrated against NIST-traceable reference)
• Relay outputs (2 × SPDT, 250 VAC/3 A) for direct pump start/stop, solenoid valve actuation, or alarm signaling
• Modular DIN-rail mounting (96 × 96 × 120 mm) with IP20-rated enclosure for integration into lab equipment racks or custom vacuum manifolds
• Non-volatile EEPROM stores up to 10 user-defined vacuum recipes with ramp-hold sequences and safety interlocks

Sample Compatibility & Compliance

The YRZK-10S is compatible with standard vacuum components used across analytical, pharmaceutical, and materials science laboratories—including diaphragm pumps, scroll pumps, diffusion pumps, and pneumatic throttle valves. It supports sensor inputs conforming to ASTM E1797 (Standard Practice for Calibration of Vacuum Gauges) and is routinely deployed in environments governed by GLP (Good Laboratory Practice) and ISO/IEC 17025-accredited testing workflows. While not FDA 21 CFR Part 11 certified out-of-the-box, its relay-based control architecture allows integration into validated systems where audit trails are managed at the supervisory SCADA or LIMS layer. All electrical safety design adheres to GB/T 18268.1–2010 (equivalent to IEC 61326-1) for laboratory measurement equipment.

Software & Data Management

The controller supports Modbus RTU protocol over RS485 for bidirectional communication with host PCs or PLCs. Optional PC software (Windows 10/11 compatible) enables remote configuration, real-time graphing of pressure vs. time, export of CSV-formatted log files (timestamped at 1 Hz), and firmware updates. Data logs include operator ID (via login prompt), setpoint changes, alarm events (e.g., overpressure, sensor fault, power interruption), and relay state transitions—supporting traceability requirements in regulated QC/QA environments. No cloud connectivity or proprietary drivers are required; communication uses standard serial-to-USB adapters compliant with FTDI or CH340 chipsets.

Applications

• Automated vacuum control during solvent removal in rotary evaporators (e.g., maintaining 10–50 mbar for heat-sensitive compounds)
• Pressure stabilization in lyophilization cycles to prevent collapse or melt-back during primary drying
• Process validation of vacuum ovens used for moisture content analysis per USP
• Feedback-controlled gas flow regulation in vacuum metallurgy test furnaces
• Integration into custom-built glovebox antechambers for controlled atmosphere transfer protocols
• Teaching labs: Demonstrating vacuum system dynamics, PID tuning fundamentals, and sensor calibration procedures

FAQ

Does the YRZK-10S support analog output for external data acquisition systems?

Yes—it provides a 0–10 V isolated analog output proportional to measured pressure, configurable via menu settings.
Can it be calibrated in-house without sending it to a service center?

Yes—two-point calibration (zero and span) is supported using a certified reference gauge; procedure is documented in the English-language user manual.
Is explosion-proof certification available for use in solvent-rich environments?

No—the standard unit is not ATEX or IECEx rated; however, intrinsically safe signal isolators may be added upstream for hazardous area deployment.
What is the maximum sampling rate for internal data logging?

Internal logging is event-triggered only (e.g., alarms, setpoint changes); continuous logging requires external PC connection at up to 10 Hz.
Are spare parts and firmware updates available beyond the 24-month warranty period?

Yes—Jinye maintains a global spare parts inventory and publishes firmware revisions quarterly on its authorized distributor portal.
