QM-211
ProSens is a new line of modern industrial devices, which integrates sensors, converters, meters and controllers functionalities. Using the latest miniaturisation technologies these compact devices are able to be equipped with one independent universal input, two binary or two analogue outputs, as well as communication port RS-485 with Modbus protocol.
Model QM-211 has integrated radial temperature or temperature and humidity probe, Ø 18 mm, L=40 mm,
PTFE filter cap.
A large built-in display and output signals mean that the ProSens line units find applications in control systems. There are many industrial applications, where ProSens can act as stand-alone controller. It can also cooperate with master devices via Modbus protocol, being part of big network, which makes it perfect device for distributed monitoring system.
