UNIVERSAL SELF-CONTAINED WIRELESS METER-SWITCH OF CONTROLLERS AND SENSORS WITH DIGITAL AND ANALOGUE OUTPUTS Russian patent published in 2019 - IPC G01R19/00 

FIELD: measuring equipment.

SUBSTANCE: invention is intended for measurement, conversion and control of signals from controllers and sensors and other devices with subsequent transmission over LoraWAN network. Wireless meter for measuring, converting and controlling pressure in a digital signal with subsequent transmission over a LoraWAN network comprises a measuring device with an output current signal of a current loop of 4–20 mA 1, the output of which is connected to the first input/output of controller 2 and input of converter 3, output of which is connected to second input/output of controller 2 and input of voltage divider 4, output of which is sequentially connected to logic switches 5, 6, located on controller 2, and outputs of switches 5, 6 and controller 2 are connected to power supply 7. Device further comprises an interfaces converter RS-485, RS-422, RS-232, Modbus; measuring device with output signals 0–0.01 V/0–1 V/0–10 V; device with output signals RS-485, RS-422, RS-232, Modbus; device with output discrete signal of "dry contact" type (8–11).

EFFECT: expansion of the device functional capabilities.
