MacREJ 5 Digital data logger with integrated 2G/3G/LTE modem designed for natural gas station parameters recording MacREJ 5 data logger designed for natural gas station and its elements parameters registration, such as: input gas pressure recording, reduced gas pressure recording, gas volume recording, gas temperature recording, reducers and the safety units supervision. MacREJ 5 is designed to work in the hazardous explosive zone 0. Working on batteries registered data sending is available according to the programmed schedule or emergency situation appearance. External power supply connection enables the on-line data access. Integrated 2G/3G/LTE modem allowing data transmission to the data acquisition systems using TCP-IP connections Temperature resistant graphical 4” display with backlight Up to 15 years work on battery External interface free configuration using NFC standard Up to 7 independent measurement channels – two integrated pressure sensors, one temperature measurement channel, four digital external pressure or temperature transducers NAMUR type sensors working on battery Universal GSM antenna connection solution Low frequency reed switch inputs PLUM Sp. z o.o.

INT-S3 | Transmission interface Performs as an external power supply to the intrinsically safe measurement device (located in stationary telemetric systems supplied from 11V-30V DC or a battery that is located in explosive zone 0, 1, or 2). Additionally, data is transmittable to a readout device (i.e. computer) via RS485 port. EM-1 | Extension module Extends the functionality of MacREJ 5 by adding two additional current outputs operating in 4-20mA current loop and four binary relay type outputs. Can operate as a standalone device as it has its own parameters that can be modified remotely...
