GfG Instrumentation 2811-709-008 EC28 Series Fixed Transmitter with Sensor, Chlorine, Display / Alarm, Modbus, 0 - 50.0 ppm Range

With Display, Alarm and Bus for Use in Ex Zones

The EC 28 DAB transmitter combined with one of GfG's reliable controllers is the perfect solution if you want to monitor toxic gases, oxygen or hydrogen and need the current measured values to be displayed locally and tranmitted digitally simultaneously. It is also capable of issuing an alarm on site. Its ATEX-certified design means it can be used even in potentially explosive atmospheres.

Functional safety

The EC28's hardware complies with the European Functional Safety Standard DIN EN 61508-2: 2011 for many gases. The SI levels (up to SIL3) in single channel (1oo1) or redundant (1oo2) use depend on the gas type and the sensor.

Communication and service

The EC28 DAB communicates via RS-485 industry standard with Modbus protocol. Its Smart Sensor technology enables quick and easy sensor replacement. Adjustments can be made using the RC2 remote control (one-person calibration).

Display, control buttons and alarms

The transmitter features a 2.2 inch LC display and three control buttons. In normal operation, the display shows the measured value or information on faults or alarms. The operating parameters (measured gas, measuring range, limit values, etc.) can also be accessed using the intuitive button controls. The EC28 DAB has highly visible, red alarm LEDs and a loud, integrated buzzer (90 dB). Costs for additional, ex-protected alarm devices can therefore be eliminated.

Reliable measurement & minimal operating costs

The sensor and built-in temperature compensation guarantee high measuring accuracy. The long sensor service life and low maintenance requirements ensure minimal operating costs.

Features:

• Concentration display at transmitter or at remote control
• Ex-proof visual and audible alarms
• No need for expensive Ex-proof buzzer or wiring
• Easy sensor replacement by means of plug-in smart sensors
• Long sensor life
• Permanent status and function display at transmitter
• Adjustments without opening the casing using touch keys or remote control; easy handling even for hard-to-reach transmitters positions (e.g. at the ceiling)
• Measuring gas and range: Chlorine, 0 - 50.0 ppm
