GfG Instrumentation 2813-740-002 EC28 i (Intrinsically Safe) Series Fixed Transmitter, Hydrogen Fluoride, Display, 0 - 10 ppm Range, 0.1 ppm Res.

Intrinsic Safety and Display for Toxic Gases, O₂ and H₂

The intrinsically safe EC28 Di transmitter in combination with one of GfG‘s controllers is a reliable and cost-effective solution, if you need to monitor toxic gases, oxygen or hydrogen in areas with a particularly high risk of explosion and want the measured values be read locally. The power supply and transmission of the measured values are carried out via two-wire cabling.

Intrinsically safe operation

The EC28 Di can be used in areas with a particularly high risk of explosion due to its intrinsically safe build. A safety barrier (SB1 or Zener barrier; optionally available) has to be connected between the transmitter and the programmable logic controller (PLC) to convert the supply voltage to 24 V DC. This prevents the power lines from igniting within Ex zones. The intrinsic safety of the EC28 Di is ATEX-certified and makes it suitable for applications up to Ex zone 0.

Communication and service

The EC28 Di communicates via a 4-20 mA signal. The Smart Sensor technology enables fast and easy sensor replacement.

Display and control buttons

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 (sample gas, measuring range, limit values, etc.) can be also be called up via the intuitive control buttons.

RC2 remote control (optional)

If the EC28 Di has to be installed in a difficult-to-access location, the RC2 remote control facilitates servicing and adjustments (one-person adjustment). The information displayed on the RC2 is identical to the one shown on the transmitter's display.

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
