Information About 084H4521
The 084H4521 is designed to measure refrigerant levels in vessels, accumulators, receivers, and standpipes. Its cable probe has a supplied insertion length of 5,000 mm. The included HMI supports local configuration with English, German, French, and Spanish language options. This cable version is suitable for specified refrigerants, including ammonia, but is not intended for CO₂ or marine applications.
Key Features:
- Guided-Wave Measurement: Uses TDR technology to measure refrigerant liquid level.
- Analog Output: Provides a proportional, two-wire 4–20 mA signal.
- Cable Probe: Includes a 5,000 mm stainless steel cable and counterweight.
- Local Interface: Supplied with an HMI for configuration and indication.
- Threaded Connection: Features a 3/4-inch NPT process connection.
- Pressure Capability: Rated for a maximum working pressure of 100 bar.
- Protected Enclosure: Features IP67 protection.
- Refrigeration Compatibility: Supports specified HCFC, non-flammable HFC, and ammonia applications.
The 084H4521 delivers the reliability and precision required for compatible refrigeration liquid level monitoring applications.
