ProSens QM-421

ProSens is a new line of modern industrial instruments. which integrates sensors. converters. meters and controllers functionalities. Using the latest miniaturisation technologies these compact instruments 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-421 has integrated axial temperature or temperature and humidity probe. ? 12 mm. L=200 mm.
stainless steel 316L probe and 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 instrument for distributed monitoring system.
