The primary functionality of ProSens is taking measurements. Depending on needs and requirements, this compact device is equipped with top quality, precise and stable temperature, humidity or air flow sensors or with universal inputs that are standard for industrial automation. Thanks to its equipment the device guarantees a very high level of measurement reliability. Both version of probes – integrated and cable ones – are made of stainless steel. The sensors are protected with a replaceable PTFE or stainless-steel mesh filter. The filter type is adjusted to a particular version of the probe.


A proper reaction of a controller is triggered by measured values interpretation, which impacts the state of output signals. Users can choose between binary outputs and analogue outputs (current and voltage ones) to adjust their model to the requirements of a specific application. Due to that the device is characterized by a wide range of various outputs and the possibility of applying them in one unit. As a consequence, the ProSens meters can be used for digital or proportional controlling, and for combining both functions in one device as well.


What is required in case of more advanced measuring and controlling networks is communication between devices. For such applications we offer the RS-485 interface which is standard equipment supporting the Modbus RTU protocol. The free S-Config software is used for communication functionalities that facilitate the device’s remote configuration without the need to use a local keyboard. Measured values and output states are shared in the Slave mode. It concerns more advanced applications with existing or required central steering and visualization systems for the devices in the ProSens line.
