QM-421_422

 

QM-422 version has axial integrated temperature or temperature and humidity Ø 12 mm, L=300 mm probe, and PTFE filter cap. Optionally is able to be equipped with one independent universal input, two binary or two analogue outputs. Universal measurement input can be set in current mode (with ranges: 0-20 mA, 4-20 mA), voltage mode (with ranges: 0-10 V, 2-10 V, 0-5 V, 1-5 V, 0-75 mV and 0-150 mV), RTD mode (witch supports: Pt 100/500/1000 sensors) and thermocouple mode (which supports: K, S, J, T, N, R, B, E thermocouples). Temperature of cold ends is compensated automatically. RTD and TC inputs are fully linearised. The relay outputs, the active current outputs, the passive current outputs, the active voltage outputs and many combinations of those outputs can work as control outputs.

Meters are equipped with mathematical functions, which make it possible to transform measured values into others, e.g. to calculate dew point, sum or difference of two measured values. 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. The devices can be configured with the local keyboard or free S-Config software via the RS-485 communication port (download in "Technical support" section).
