Ripening Gas Sensors & Controller


GAs Sensors



Ethylene Gas Sensor:


This is a transmitter of gas concentration measured in the range of 0 – 2000 ppm.


It has a LED-display to show the real-time value and a standard linear output 4 – 20 mA to transfer the data to external display units. The transmitter is mounted on a wall. The measuring element is a catalytic sensor. The transmitter can be easily calibrated with using a calibration gas mixture with known ethylene concentration. 

We also offer InfraRed transmitter to measure Carbon Dioxide gas in the range of 0 - 5%.

Gas Controllers

XT Controller:


Two-stage ON/OFF controller of gas concentration (like ethylene and CO2 transmitters). The controller perfectly works with standard 4 – 20 mA probe‘s outputs, but a voltage should be chosen (0 – 1 V or 0 – 10 V).

The measured quantities are shown on a 3½ digits LED display with a numeral height of 10.5 mm. The control function is realized with 2 probe relays. Minimum and maximum set points values can be programmed by a user.
