EC28 DAR Transmitter
Display, Alarm and Relay for Safety in Ex Zones
Whenever toxic gases, oxygen or hydrogen are to be monitored and a display of the current measured value as well as local and external alarms are to be provided on site, the EC28 DAR transmitter combined with GfG‘s proven control units is the solution of choice. The ATEX-certified design means it can be used even in potentially explosive atmospheres.
Communication and Service
Communication is carried out via a 4-20 mA signal. The Smart Sensor technology enables fast and uncomplicated replacement of the sensor. Adjustments can be made using the RC2 remote control (one-man calibration).
Display, Control Buttons and Alarms
The EC28 DAR 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. In addition, the operating parameters (sample gas, measuring range, limit values, etc.) can be called up via the operating keys. The EC28 DAR has highly visible red alarm LEDs, an integrated loud horn (90 dB) and an additional relay. This results in the possibility of triggering visual and acoustic alarms locally and simultaneously externally via optional alarm transmitters such as flashing lights, horns and information signs.
Reliable Measurement & Minimal Operating Costs
The sensor and built-in temperature compensation ensure the highest measuring accuracy. The long sensor service life and low maintenance requirements ensure minimal operating costs.
