Universal Wireless All-Rounder for Humidity, Temperature and CO2 Content

The future of the measuring devices is wireless - wireless communication is a cornerstone of intelligent devices. The digital JUMO (Germany) Wtrans E01 measures humidity, temperature and CO₂ content and is designed for the most demanding applications in the field of surveillance. The multi-point CO₂ and temperature adjustment results in excellent CO₂ measurement accuracy over the entire temperature range. The Wtrans E01 is ideal for use in agriculture, industry, storage and outdoor use.

Can be connected to the unit are probes for the physical quantities of CO ₂ , humidity, temperature and resistance thermometer with PT1000 temperature sensors. The Wtrans E01 features a USB interface for comfortable configuration of each paramater. Power supply is via standard AA batteries or a 24 V power supply with SELV. An alphanumeric display shows all measured values. The powerful high-frequency circuit then sends all data via radio to the receiver up to 600m away. For further processing, relay contacts, analog outputs and a digital Modbus interface for reading up to 4 Wtrans E01 stations are available.

Due to the NDIR two-beam method, the CO₂ sensor is maintenance free and highly resistant to contamination. The CO₂ measurement operates according to the infrared principle (NDIR). A patented auto-calibration procedure compensates for the effects of aging and ensures long-term stability. The air to be monitored is passed through the measuring head and a short tube to the measuring cell housing. The gas exchange with the measuring cell is via a membrane by diffusion. Dirt loading of the optical measurement path and related inaccuracies is thus prevented.

There are three variants of CO₂ measuring ranges from 0 to 2000/5000/10.000 ppm to choose from. The measurement interval may be adapted to the requirements of the application; battery-powered devices can thereby reduce the average power consumption. 

With the ability to contact all probes by means of M12 connectors with the Wtrans E01, creates the highest possible flexibility and a more customer-friendly exchange in all fields and applications. The JUMO Wtrans family may be freely combined with each other, since the receivers are compatible with all devices in the series.
