CRM-111-1 Differential Pressure Monitor
The CRM-111-1 Differential Pressure Monitor is a versatile device designed for various applications, including clean rooms in pharmaceutical environments, HVAC systems, animal house clean rooms, and cold storage facilities. Equipped with a built-in differential pressure Monitor featuring chrome-plated brass hose nozzles, this sensor provides accurate measurements within specified ranges. The 4-digit seven-segment LED display offers clear indication of differential pressure, while two user-programmable alarms (AL1 and AL2) with integrated buzzer ensure timely notifications for pressure limit violations. The device also incorporates a password-protected programming for added security.
1. LED Display: 4-digit seven-segment LED display provides clear and easy-to-read indication of the differential pressure monitor.
2. Alarms: Two user-programmable alarms (AL1, AL2) with integrated buzzer offer timely notifications for pressure limit violations.
3. Calibration: Software calibration feature ensures accurate and reliable pressure measurements.
4. Status Indication: LED indicators (‘AL1’ and ‘AL2’) for alarms and ‘COM’ LED for communication status provide visual feedback.
5. Communication: Isolated RS-485 with Modbus RTU Protocol enables seamless integration with PLCs and SCADA systems.
6. Current Output (Optional): 4-20mA output with 680Ω load capacity and high accuracy (0.125% FS) for compatibility with control systems.
7. Environmental Compatibility: Operating ambient temperature range of 0 to 50°C, suitable for a variety of environments.
8. Humidity Resistance: Designed to operate below 95% RH, non-condensing, ensuring reliability in varying humidity conditions.
