Monitoring, Data Logging and Control System Surveyor



 Envitech Europe Surveyor

General Aspects


The Surveyor data logger is a small, ultra low power, cost effective data logger with built-in 4G cellular modem. This small data logger, is further provided with an internal temperature sensor, 8GB micro SD card and a 2FF SIM card slot. The data logger is available with several power provisions a/o: 3.6 Volt Lithium battery, 8..28V DC-input or integrated solar panel with 3 x AA NiMH charger.
The data logger can acquire physical signals by 2 current loop inputs, 2 voltage inputs, 1 potentiometer input and 3 digital inputs. More or special inputs can be added by means of internal stackable option boards/converters. The data logger is provided with one serial port to capture measurements from ASCII, MODBUS, NMEA or SDI-12 compatible sensors. External sensors can be powered by the data logger itself, to prevent them to consume power while the data logger is a sleep. Up to 8 mathematical channels are available to calculate meaningful engineering values derived from sensor input values (e.g. a polynomial to calculate a flow from a stream level). Supports up to 8 aggregation channels (e.g. to record 2 or 10 minute windspeed averages sampled at 1Hz). Logged data can be pushed to a central host by HTTP(S), FTP(S), e-mail, secure TCP or MQTT at configurable intervals and optionally by satellite as well (Iridium SBD).

TheSurveyor is available with: 4G Global (LTE-M) with 2G fall-back or 4G Europe (LTE Cat 1) with 2G fall-back or 4G North-America (LTE Cat 1)
When equipped with the integrated solar panel a complete self providing remote monitoring station can be arranged, all you need is a data logger and applicable sensor(s). This self providing cellular data logger is costs saving, because you don't need: a) solar panels, b) big batteries, c) cellular modem and d) encapsulating cabinet.
