Grain Monitoring System

Grain Temperature Monitoring System

The EST series is a grain temperature monitoring system for use in monitoring grain quality in storage through multiple point temperature measurement within each grain bin.  The product line consists of two types of sensor cables, the EST110 grain temperature monitoring cable and the EST120 temperature/level monitoring cables.  Each use state-of-the-art sensing technology to minimize installation costs and maximize performance and value.  Readout via PC-software and a future wall mounted graphic display/keypad interface.





  • Multipoint temperature monitoring for aiding grain quality management
  • Temperature and level measurement in a single cable


  • Agriculture
  • Feed and grain processing
  • Grain distribution

Unique simultaneous monitoring of grain level and temperature.
Reinforced steel cable design effectively provides long life.
Multiple point temperature measurement, up to thirty (30) 1-wire digital sensors per cable with
custom spacing.
Detect “hot spot” temperature rises that may indicate pest infestation or mold growth to allow for
quick response to eliminate trouble.
Provide realtime grain storage temperature for long-term grain storage facilities, grain processors
and feed mills.
Easy to setup and calibrate level measurement function using any two points.
RS485 (MODBUS) digital communications easily integrates into your existing system while
simplifying and reducing overall system installation costs

The EST110 grain temperature monitoring cables use simple high performance 1-wire digital temperature sensors that can be located at multiple points within a single cable of overall length up to 98.5ft (30m).

The use of these digital sensors simplifies installation as only a pair of wire is needed from each multiple point grain temperature monitoring cable. Each cable will connect locally at each grain bin to our HubLink data processor which provides an easily installed RS485 MODBUS 2-wire connection into the system. Multiple HubLink units can be daisy-chained with a single 2-wire cable to the PC or operator interface. Aplus Finetek's MMS-TLA series software provides the graphic interface to the entire system.

The EST120 combines multiple point temperature sensing using 1-wire digital sensors with continuous capacitance level measurement to provide an RS485 MODBUS connection into the system with or without HubLink units to the MMS-TLA PC software or RCU wall mounted graphical interface.
