GD premium
The Premium line gas detection units are used for monitoring and warning of hazardous gas concentrations. They can be used for detecting most commonly used refrigerants. Depending on the application and model, each unit is available with one or two of 4 sensor types.
The Premium line gas detection units are intended as Stand-alone, or connected to a central system like Gas Detection Controller Unit, or a PLC.
As stand-alone the on-board relays can be used for activation of alarm devices, while the Analog or RS485 Modbus connection to a central system allows additional centralized monitoring and alarm activation.
4 out of the 6 Premium models have integrated Display/keypad for direct access to the user interface.
The gas detection units come with a factory default, 2-step alarm set-up ready for use. The user interface enables the user to configure two individual alarm settings.
Features and benefits
- Digital, factory configured and pre-calibrated gas detectors for plug-and-play installation (no adjustment required)
- Easy configuration via Display/keypad (some models) and intuitive user-interface; helps simplify operator handling and minimize risk of operational, settings and calibration errors
- Stand-alone (integrated relays) and/or flexible connection to central controller - by either Analog or RS485 open Modbus communications
- This device supports a wide selection of refrigerants, sensor types, and detection ranges. It is available in two sensor versions, and remote sensor location is also possible.
- Fieldbus wiring - connect and power up to 96 sensors, wire length max. 900 meters (2953 ft) per segment; expansion modules permit additional segments
- To ensure correct operation and enhance sensor accuracy, the unit performs automatic self-diagnostics and utilizes a digital user interface. Additionally, a sensor seal cap is included to protect the sensor during installation.
- For enhanced reliability and security, the unit uses temperature-compensated sensors to reduce false alarms and features password-protected settings for authorized access, with clear status and alarm indication via LEDs.
- The unit features an optional buzzer and light for local audio and visual alarms (Premium+, Premium Uptime) and includes an on-board acknowledge button to reset alarms and verify that no gas leaks are present
- The device features service alerts on the unit, controller, or both (readable via the service tool display) and supports quick, precise calibration procedures. Calibration can be done easily through either plug-and-play sensor replacement or with gas, with no need for potentiometers or multi-meters
- For enhanced safety and optimized sensor life, the calibration process automatically rejects degenerated sensors with low sensitivity (<30%). The device conforms to EN 50271, EN 61010-1, ANSI/UL 61010-1, and CAN/CSA-C22.2 No. 61010-1, and enables regulatory compliance with EN 378:2016, ISO 5149:2014, IIAR 2-2017, and ASHRAE 15:2016.
