2109-500 EC 21 Fixed Gas Transmitter with Internal Sensor, Ammonia (NH3), 1 ppm, 0 - 500 ppm by GfG

GfG s EC 21 transmitter for detecting toxic gases in ambient air is an inexpensive gas detection solution for use in a wide variety of today's industrial applications.

Simple gas detection

The EC 21 is the simplest way to monitor ambient conditions. Simply attach the EC21 to a GfG controller or a PLC to continuously and efficiently monitor the concentration of hazardous toxic contaminants in the air.

The EC 21 is reverse-wire protected to prevent damage due to incorrect wiring of the device. The power connector hasa "quick disconnect" feature to simplify transmitter installation and service.

Mounting Position of the EC 21

To determine the mounting position of the EC 21 it is important to know and consider the ambient conditions. To achieve the best results, the ventilation conditions and the density of the gases need to be considered.

The EC 21 must be installed so that the gas reaches the sensor even in poorly ventilated areas. If necessary, check the area with a smoke cartridge.

Other influences such as water (rain, dripping or condensation) and dust need to be considered as well.

Features

• Simple to use and extremely economical
• Robust housing is corrosion resistant and dust-tight>
• Linear 4 to 20 mA output signal
• 18 - 24 VDC

22210-02 ZD 22 Fixed Gas Transmitter, No Display / Modbus by GfG

Superior technology

The ZD 22 Transmitter is specifically designed for long-term monitoring of oxygen concentrations. The integrated amperometric oxygen sensor is based on an electrochemical oxygen pumping cell made of zirconium dioxide. It is characterized by its robustness, a very high life expectancy and its outstanding long-term stability. The integrated thermostatic control of the sensor element achieves accurate measuring results in the entire temperature range, regardless of the operating temperature. It can also be permanently used in environments with high concentrations of CO2 or in dry atmosphere. Special equipment is available to protect the transmitter when used in harsh environments.

Signal processing

The protective casing (IP 54) of the ZD 22 Transmitter contains the complete signal processing electronics and the failsafe routing of the measurement signal for the measuring computer, with extensive self-monitoring. The embedded software linearises the measuring signal and compensates for the effects of temperature. As a result, correct readings are transmitted even with weather related fluctuations in temperature. In addition, the transmitter can be connected to a gas measurement computer for the option of transmitting service, maintenance, and error messages.

Universal signal transmission

The ZD 22 Transmitter transmits the signals either using an analog (0.2 1mA / 4-20 mA) current interface or a digital (RS485) Modbus interface. This permits the universal use of the trasmitters in combination with GfG gas measurement computers and thus connection to a safety system, so that you and your systems will benefit from the best possible protection.

There are a variety of applications for the ZD 22 in regard to sensors, status LEDs and optional analog or digital interface, "Zero" key to calibrate the zero point, test socket and a potentiometer for the calibration of the sensor.

Weather protection

A weatherproof housing not only protects transmitters against exposure to wind and weather, but also against contamination and excessive temperatures caused by direct sunlight.

Optional colored graphic display

The clear graphic display of the ZD 22 is self explanatory and allows you to read the current status and other important information with ease. The display enables you to navigate effortlessly through the unit s concise menu and to change settings or even calibrate, depending on your user authorization. In the event of an alarm the display changes color from green to red. Two LEDs indicate the status.

Operation buttons

The buttons on the transmitter allow the unit to be calibrated and settings to be adjusted through the menu as needed.

Calibration adapter

In order to perform a calibration, a calibration adapter is used on the transmitter, which ensures a uniform and secure supply of gas.

Easy and convenient service

GfG offers full after-the-sale commissioning and field service support.

• Long service life of the sensors
• Extremely fast response time: t90 < 5 sec.
• Reduced pressure, humidity, or temperature influence
• No damage due to CO₂
• Cost effective single-man adjustment
• Affordable operation costs
