Temperature, humidity and CO₂ sensors by Evikon

Evikon is an Estonia-based business focused on the design and manufacture of sensors/measuring transducers. The company offers most of the basic types of sensors used in industrial automation.

We would like to recommend to you the assortment of Evikon transducer/transmitter modules. They are designed to measure environmental data: temperature, humidity, pressure and carbon dioxide concentration in the air (depending on the model). The two most important features of these products are that they are factory-designed for wall (or duct) mounting and come in the form of RTUs (Remote Terminal Unit) for systems using the popular RS485 standard of Modbus interface. In addition, selected models can be equipped with analogue outputs: current outputs which operate at 4–20 mA or voltage outputs (from 0 V to 10 V DC), as well as relay outputs, the purpose of which is to connect circuits (e.g. ventilation or warning signalling circuits) when preset values are exceeded. Some versions feature a built-in buzzer.

The products are equipped with high-quality, reliable and functional electronic components that operate over a wide range of parameters. They are enclosed in IP65-rated housings (complete protection against dust and moisture/splashing/water jets). Factory-fitted glands are intended for inserting probes and lead wires, which helps maintain the structural integrity of the unit.

The transducers/transmitters presented here are capable of measuring temperature in the range from -50°C to 200°C, pressure in the range from -500 Pa to 500 Pa (differential measurement), CO2 concentration up to 10000 ppm and humidity from 7% to 20% H2O. With their versatile performance, high ingress protection rating, and a choice of interfaces, Evikon products are an attractive solution for a variety of industrial applications, HVAC and air quality monitoring systems (more info).
